IoT Standards

I’ve been attending some of SAE International’s mobility meet-ups lately.  These gatherings are focused on automated vehicles, of interest to many here in Silicon Valley.  As I meet the other attendees, I often hear questions about the state of standardization with regards to IoT, the Internet of Things.  So today I’m providing you with some information on IoT Standards.

IoT Standards actually cover a lot of ground.  These documents provide the connectivity protocols for linking things to the network.  A number of them have been in use for quite some time.  However, the proliferation of devices that gain functionality when connected puts a strain on the standards process.  In order to be universal, standards have to be developed in advance of implementation.  This is the challenge that new technologies bring to our standards processes.

Consortia have often been used to develop standards in emerging technologies.  They tend to be narrowly focused with an urgent need to reach agreement.  One such group operating in this space is the Open Connectivity Foundation (OCF).  Started as the UPnP Forum, this group has expanded it’s mission over time.  They are also of particular interest as they have taken the standards they’ve developed and sent them up into the ISO/IEC system via JTC1 (the Joint Technical Committee 1).

An example of this is the series of IoT standards known as ISO/IEC 29341-30. These documents focus in on the UPnP functionality – Universal Plug and Play.  They are used by many of you, essential for the many home networks for connectivity between devices.  The OCF developed this series first and then used the ISO/IEC adoption protocol for publicly available specifications (PAS) to transform them into international standards.

Needless to say, there are many consortia working in this space.  You’ll also find applicable standards activities happening in the traditional Internet standards spaces (IETF and WC3 for example).  And of course, our more mainstream standards bodies are also busy working on new standards in this space (ETSI, ISO/IEC JTC1, IEEE and so on).

Here is a list of IoT standards that are currently available from ISO/IEC:

  • ISO/IEC 20922:2016
    Information technology – Message Queuing Telemetry Transport (MQTT) v3.1.1
  • ISO/IEC 21823-1:2018 PRV

    Information technology – Open Connectivity Foundation (OCF) Specification – Part 5: Smart home device specification
  • ISO/IEC 30141:2018
    Internet of Things (IoT) – Reference architecture

You can see they are a mix of IoT standards that have been pushed up, like the ISO/IEC ISO/IEC 29341-30  series, and those that have been developed at the International level itself.

However, there is definitely a need for more standardization and consensus in this space.  Since it is a hot area for product development, we can expect a mix of successful and failed standards.  But as usual, the drive for development of protocols in advance of the investment required for new product will insure that this space will be very active for some time to come.

BSI will remain in CEN/CENELEC after Brexit!

As you probably know, the future of the UK’s involvement in the European Standards system has been in question ever since Brexit became a reality.  So I’m happy to let you know that BSI will remain in CEN/CENELEC after Brexit.  We’ve known for some time that it would take a modification of the rules to allow for this.  On November 23, 2018, a vote was taken.  BSI will be able to remain a full member of both CEN and CENELEC, the European equivalents of ISO and IEC.

BSI had 8 areas of concern that led it to work towards a modification of the rules to allow it to stay involved in CEN/CENELEC should the U.K. withdraw from the European Community.  Here’s the list:

  1. Standards provide a passport to trade.
  2. The European standards system has simplified the market structure in
    Europe through the use of the single national standard model across
    34 countries in the region.
  3. The European standards system is neither owned by nor is it an
    agency of the European Union.
  4. The UK has significant influence in the development of European
    standards.
  5. Maintaining full UK membership of CEN and CENELEC is important
    to the success of business in Europe post-Brexit.
  6. Maintaining full CEN and CENELEC membership also brings benefits
    to consumers and other public interest groups.
  7. BSI must therefore continue as a full member of CEN and CENELEC
    post-Brexit.
  8. Standards will provide a key element underpinning future free trade
    agreements between the UK and non-EU countries.

Apparently, until now the administrative rules governing CEN and CENELEC required membership in the European Union.  This solution has needed a 100% in favor vote from the existing stakeholders.  The positive outcome for BSI represents a political success as well as a pragmatic one.

How does this affect Document Center Inc. customers and other standards users?  BS EN standards will remain valid for use when trading with the European Union.  So any collection of BS EN standards used in your company can be left in place without worry.

Additionally, I would mention that at the recent ISO General Assembly in Geneva, there was much discussion of the role of standards and standardization in continuing the trend towards global free trade in spite of current political rhetoric.  This vote within the European standards bodies reflects the desire of many in our community to foster larger global goals.  After all, some of the most fundamental reasons for standards rest securely in the domain of public safety and well-being.  This development will surely bring a sigh of relief to many.

BSI has a press release and earlier position paper you can review to learn more.  If you have further questions, please get in touch with us.  We can be reached at info@document-center.com or by phone at 650-591-7600.    Should you want to review the status of any of your EN standards, please search on our website www.document-center.com.  We track and sell over a million standards for you.  As you can see, Document Center Inc. is committed not only to providing you with standards, but also the information you need to use your standards collection with confidence.  Make us your Standards Experts!

What’s up with the new EN-IEC standards?

Lately some of the EN IEC adoptions have been renumbered as EN-IEC standards.  Our Document Center customers are asking us why this change is being made.  So when I was in Geneva Switzerland last month, this was one of the questions that I wanted answered by my European colleagues.

To my delight, Elena Santiago, the Director General of CEN and CENELEC, was a featured speaker at our IFAN (the International Federation of Standards Users) General Meeting.  I had a chance to speak with her during a break.  Of course, I had a number of questions for her, and one of them was about the new EN-IEC numbering.

Ms. Santiago explained that the new releases are the culmination of work begun a couple of years ago at the request of the CEN and CENELEC membership.  The mandate is to bring the identical EN adoptions of the IEC standards into line with the protocol for the adoptions of the ISO standards.  So the IEC adoptions are being reissued with a new number scheme that includes the IEC designation.

Why?  “For traceability,” said Ms. Santiago.  CEN and CENELEC members want the same clear acknowledgement of lineage that has always been a part of the ISO adoptions.  So now when you see the EN-IEC standard designation, you know that you are looking at an identical EN adoption of the source IEC document.

Of course, I had more questions than this!  One of them that’s getting a lot of attention from standards users in general is the issue of Brexit.  Ms. Santiago not only discussed this with me, but also touched on it during her presentation.  She is hopeful that during the CEN CENELEC meetings in November a vote can be taken to modify the membership rules of the organizations.  With this change, the U.K. can continue to participate in and use the EN standards system.

I’m sure we’ll all be waiting to see how this particular story ends!  Meantime, I’m glad to be able to shed some light on the new EN-IEC standards designation for you.

If you need to see if an EN standard you use is current and correct, please check in with our Document Center Sales Staff at info@document-center.com.  Or call us at 650-591-7600.  You can also look up any of the standards you use on our website, www.document-center.com.  Any further questions, please ask.  We’re here to help.

IEC TR 63097 – Roadmap for Energy Smart Grid Standards

IEC TR 63097, the Smart grid standardization roadmap, has just been released.  It’s a new 320-page Technical Report outlining the way forward in developing the smart power grid.  Companies need to prepare for the long-term impact of technology and interconnectivity.  Without widespread adoption of compatible standards, the development of next level power grid applications will not be possible.

IEC TR 63097 is an example of the importance of standards development supporting technology advances.  This model of setting standards in advance of technical product development and implementation springs from the telecommunications industry.  With ITU in the lead, that industry has been setting global requirements prior to actually providing products and services.  This is quite unlike the traditional standards process, where standardization is the final step in the process.

In any sector facing rapid technological changes, a common question is “What standards should I be using?”  The IEC TR 63097 provides you with guidelines to select the most appropriate set of standards and specifications supporting the smart grid.  However, in some cases, those standards have yet to be completed.

So what will you find in the IEC TR 63097?  The document begins with the usual scope, referenced documents and definition sections.  Then it discusses the Smart Grid context, including drivers and definitions of the Smart Grid itself.  The bulk of the text of the standard is contained in Clause 5.  It’s divided into 10 sections, each on a specific area of concern.  These may be general, like Clause 5.1 with its high-level summary or 5.2 on the general framework.  Other sections present information like the use of the Smart Grid standards map, use cases, interoperability, expected evolutions, cross-cutting technologies, and standards for specific areas relating to smart grids.

There are 2 Annexes.  Annex A consists of a series of tables, presenting a list of standards on the left and the technical areas covered by each standard on the right.  Annex B covers core IEC Standards for smart grids.  Each standard or standard series is reviewed with text and figures (like graphs and the like).  These Annexes are informative only, but of great assistance to the user.

To get your copy, you’ll follow IEC’s instructions to purchase from an authorized distributor like Document Center Inc.  Our webstore at www.document-center.com has been selling the IEC standards under license agreement since the 1993.  Here is a direct link to the order page for IEC TR 63097 for your convenience.

Document Center standards purchases come with our “best-in-class” notification as part of your transaction.  Other compliance documentation products and services are available as well.  For more information, contact us by phone (650-591-7600) or email (info@document-center.com).  Find out why so many people make us their Standards Experts!

How did you become a Standards Professional?

I was one of the mentor’s at ANSI’s Standards Simulation contest at San Jose State University last week.  And one of the questions students asked me was “How did you become a Standards Professional?”  In fact, ever since I have become involved in the standards community at large, this is a frequent question.  People want to know what career path leads to participation in standards activities.

Now the Asia-Pacific Economic Co-operation group APEC is going to find out!  Their Sub-Committee on Standards and Conformance (SCSC) is conducting a survey on this very question.  And best of all, if you take the survey, you’ll get a free copy of the results.

What is APEC’s Sub-Committee on Standards and Conformance?  The SCSC was established in 1994 to promote understanding and usage of standards in the Asia-Pacific region.  It was developed for a number of reasons.  First, this region has been very interested in using standards to facilitate international trade.  Second, Asia has been increasing participation in International Standards activities (ISO, IEC, and ITU).   Why?  For the sake of harmonization of standards in this area with international norms.  So a focal point for educational activities is warranted.  And lastly, greater reliance on standards promotes improved production integration with global partners.  All these activities have helped improve the economies of the APEC member countries.

What is the SCSC survey about?  The survey (located at https://ko.surveymonkey.com/r/WDKW3K8) is a questionnaire for standards professionals in both industry and in Standards Developing Organizations.  It aims to identify both the career path of standards professionals and map the reults.  It also asks about skills and the knowledge base required for those in the standards community.  In the end, the survey will be used to create recommendations for SCSC projects to inspire folks in the region to enter this field.

Who should take this survey?  Anyone who is a standards professional!  But you’ll need to act prior to December 15, 2017.  When the survey is complete you’ll get a copy of the survey summary results.  Since the company and individual information will not be publicly available, this is one of your few chances to gain access to this critical information.  It should be completed around March of 2018.

Hats off to APEC’s SCSC for undertaking this survey.  And also to Donggeun Choi from KSA (the Korean Standards Association) for taking the lead on the project.  We’re very interested in seeing the results of this work on “Inspiring the Next Generation of Standards Professional Development – Phase 2: Developing Career Path and Career Map.”  It is a great adjunct to other educational efforts like the ANSI Standards Simulation Competition that I participated in last week!

U.S. Celebrates World Standards Day 2017

 

Today is the day we in the U.S. are celebrating World Standards Day 2017!  And the theme this year is “Smart Health.”  The celebration is led by ANSI, our U.S. standards “umbrella” organization.  And fittingly, this year’s activities are being sponsored by AAMI, the Association for the Advancement of Medical Instrumentation.

Every year at this time, ANSI hold a series of meetings in Washington DC to gather standards professionals and other interested parties together.  Topics are presented to address the specific concerns of standards developers, users, and other in the ANSI standards community.  The culmination of the week is the World Standards Day dinner.  This provides a venue to recognize achievements by various stakeholders across the standards community.

A highlight of the evening is the presentation of the Ronald H. Brown Leadership award.  This award honors an individual who has promoted standardization as a tool to eliminate global trade barriers.  Other awards include the winner of the World Standards Day Paper competition.  Additional honors provide a national platform for service recognition, not normally available in other gatherings.

The topic, Smart Health, is a great one for World Standards Day 2017.  We’re seeing rapid advances in the use of mobile communication platforms in a number of areas.  One feature of this “new world” is the merging of technologies in ways that challenge the standards communities focus on inter-connectivity.   Certainly the healthcare and medical device industries are in the lead when it comes to using new platforms and capabilities.  AAMI has been an active player at both the national and international arenas to promote development of standards that benefit both industry and the public at large.

One thing that I’ve always appreciated about the World Standards Day dinner is the visibility of standards participants across industry and government.  The evening truly highlights the universal value of standardization for our national and global communities.  Standards are critical to both our economic well-being and our public safety.  Hurray for a day to celebrate the service the standards community provides to us.

Handling Standards Correctly

I was at the Standards Update for the SLA (Special Librariies  Association) convention in Phoenix this week.  (Yes it was very hot down there!)  And a question came up about Interlibrary Loan (ILL).  The question was, can a standard be sent from one library to another using ILL?  I figure if a librarian has a question about how to correctly handle these copyright documents, maybe you have a question about this too.

The first thing to recognize is that there is a big difference in how you should handle the standards you purchased based on the format you buy.  Copyright law is very clear that when you purchase information in one medium (paper, pdf, e-book, and so on) you do not have the right to transform it into any other format.  So it is illegal to scan a copyright paper document for any reason at all.

Also, you need to take into consideration the fact that when you purchase most standards in pdf format, you accept a license agreement in the process.  Usually, the license restricts your ability to distribute the item.  In other words, most of the time you are getting a single user license that allows you to keep the pdf file on 1 computer for the use of 1 person only.  Ergo, no further distribution at all.

However, if the license does allow you to print 1 paper copy, this is a different kettle of fish.  As all of you library users know, it is entirely legal to loan a paper-based document/book to others.  What are the rules?  It has to be the physical copy that you purchased.  This extends to a printed paper copy as long as it’s within the bounds described in your license.  If you’re allowed 1 printed copy from your pdf file, that’s the only paper copy you can use or share.  No additional print copies are OK.

So a library or organization can take a legally purchased paper copy and loan that copy only to another entity.  This is the concept behind the use of Interlibrary Loan.  And it means that you have this right too.

However, when working with standards you should always remember that you are not a standards distributor.  You can share a print copy with others.  You can have someone else sit at your desk and take a look at a pdf copy you purchased.  And you can and should back up the pdf documents you buy in case of a computer disaster.  But you are not allowed to take a standard you purchase and freely give additional copies to your friends and neighbors.  You must adhere to the rules of copyright.

Why is this especially important in the world of standards?  The consensus standards system of the United States is based on the use of volunteer experts and others to create this valuable data.  The administration of this system is rigorous and costs money.  When you buy a standard, most of the purchase price goes to support this system.  Without the revenues generated from the sales of standards, our system would collapse.

Other information sets are becoming contested.  Many find that they no longer have confidence in the information they are getting from various channels.  Standards must be trusted — it’s not up for discussion.  The information in the standards you use must be complete and correct.  So the current system fulfills a valuable requirement in assuring safety and inter-connectivity of the things we make and use.

Knowing that standards are developed in a consensus fashion, by experts but with public review as an essential element, gives us the assurance we need.  Your compliance with copyright and purchasing your standards from reputable and authorized sources like Document Center Inc. keep this system viable.  Thanks so much for supporting the standards system by following the rules of copyright.

And if you ever have a question about other ways to use the standards you purchase within your organization, please check in with us.  You can reach us by phone (650-591-7600) and email (info@document-center.com).  Our Standards Online service can give you wider accessibility within legal bounds.  After all, it truly is a partnership between the standards developer and you, the standards user.

NISO Z39.102 Draft available for public comment

I’m at the Special Libraries Association Standards Roundtable today.  So I like to highlight a standard of interest to librarians at the same time.  And I’m in luck!  There a new draft NISO Z39.102 that is not only important to librarians but to the rest of the standards community as well!

NISO Z39.102 is titled STS: Standards Tag Suite.  It provides a common XML format for use in standards documents, both the metadata and the content text.  It represents a milestone in the effort to provide standards information in an “intelligent” format.  It will help standards developers and publishers achieve a long-standing goal that first appeared with the release of the SGML standards of the 1980’s.

What is tagging? Actually, you are probably more familiar with the concept of tagging data than you realize. For example, HTML used on web pages is just a form of content tagging.  So when you look at the source data for this page, for example, you’ll see “tags” that include the symbols “<” and “>” in them.  The data within the tags is used by computer programs to identify things like paragraphs and so on.

In XML tagging, and specifically in this type of tagging for standards, an agreed-upon set of informative tags allow computers not only to recognize layout requirements, but also content types.  So we’ll see tags for such things as scope material, referenced documents, tables of contents, and so on in this new draft.

Why use this type of tagging for standards?  NISO Z39.102 will create a consistent methodology for identifying specific areas within standards documents.  Users will have delivery tools that will increase the value of these publications.  You may be able to link from a paragraph in one publishers document to a paragraph in a standard from another source.  The real-life relationships between standards will be realized in the tools you use to work with these data sets.

Standards professionals realize that standards are “living”documents.  They are constantly being reviewed and updated as new factors present themselves.  The use of XML represents a realistic scheme for allowing users better insight into these changes.  And it will further reinforce the interrelationships of the data contained in the universe of standards themselves.

If you have further questions, please get in touch.  You can reach me and the Document Center Inc. staff by phone (650-591-7600) and email (info@document-center.com).  We have been following the evolution of standards data since the 1980’s.  We are happy to help you understand what these changes will mean for you and the standards community at large.

 

 

The Lasting Legacy of Mil Spec Reform

There are some topics that just won’t go away and Mil Spec Reform seems to be one of them!  The changes made by Secretary Perry in 1994 still ripple throughout the standards community.  And I still get questions about what standards to use that lead back to this historic transformation.

Mil Spec Reform started in the mid-1990’s as part of the DoD’s cost-cutting measures.  It was kicked off by a memo by Secretary Perry in July of 1994.  The memo directed the DoD (Department of Defense) to withdraw mil specs and standards whenever possible in favor of industry standards.  It revamped many of the conventions used during procurement.  And it cited not only cost savings but also adherence to industry norms and access to advanced technologies as reasons for the changes.

The first evidence of the extent of the proposed changes came with the release of the “Hot 105 List.”  This list was a compilation of the specs and standards deemed not only unnecessary but also to cost the U.S. government the most money.  Many of the most widely-used standards were on that list — the MIL-STD-105, MIL-STD-45662, and so on.  Of course, as these documents were withdrawn, industry was in shock! The publications were used not only for military procurement but also for many commercial transactions.

Mil Spec reform did go through. Changes have been extensive within the military, both in procurement processes and in documentation support.  Let’s take a look at some of the lasting impacts.

  1.  Mil Specs and Standards cancelled during this period have been replaced in many cases by industry standards.  And some of those standards are direct adoptions of the military documents themselves by various industry standards developing organizations (SDOs).  So for example, you will see many SAE standards that contain elements of the Mil Specs and Standards they replaced.  Samples are AMS-STD-595 for Federal colors and AMS-STD-2154 for ultrasonic inspection of wrought metals.
  2. Government participation in industry standards development has risen.  Many organizations have developed standards that not only meet commercial requirements but account for government needs as well.  So standardization has bridged the gap between the needs of these two groups in many cases.
  3. The DoD has achieved a reduction in the cost of it’s standardization program.  It no longer needs to certify its suppliers — third parties are now hired for quality and other compliance certifications.  And for the military, the cost of purchasing industry standards is far less than the cost of writing and maintaining a separate system specifically for their own needs.
  4. The cost to industry has risen.  Under the old system, the exclusive use of mil specs and standards was very inexpensive.  The documentation was basically paid for by taxpayer dollars.  However, with reform came an increased cost for suppliers.  Industry standards come with a price tag, sometimes a rather steep one!  And the costs of certification can be expensive as well.
  5. There continues to be some confusion about what documentation to use now that most of the popular Mil Specs and Standards are withdrawn.  This is in part due to the fact that the industry standards collection is far more diverse than the DoD one.  So for example, when trying to determine what should be used in place of the MIL-STD-45662, you have a choice between and ISO standard and an ANSI one.  You’ll have to either depend on contracts to point the way for you or make an evaluation of both documents to determine what is best for your organization.

Mil Spec Reform has an on-going legacy.  It has allowed for huge improvements within the DoD.  It has supported the use of advanced technologies to protect our forces in the field.  It has made the military more cost-effective.  And it has pushed many commercial organizations into the use of industry documentation.

If you have questions about the migration path for any of the obsolete mil specs and standards, please get in touch.  You can reach us by phone (650-591-7600) and email (info@document-center.com).  Some documents do not have a clear path, but many do.  We’ll be happy to help you follow the trail where ever possible.  For a more complete discussion of Mil Spec Reform itself, take a look at Richard Shertzer’s article on the subject.  It’s an in-depth analysis of the process.

And you may just want to look up the obsolete publication at our webstore, www.document-center.com.  We have a catalog of over 1 million publications for you to browse and order from.  Many withdrawn documents have replacement information in the bibliographic record.

What is the difference between ANSI Z540.1 and ANSI Z540.3?

The replacement of the ANSI Z540.1 with the ANSI Z540.3 and the ISO/IEC 17025 back in 2007 has led to a number of questions from Document Center Inc. customers.  To help you understand the situation, here’s a review of the migration path.  And we’ll discuss the differences between the ANSI Z540.1 and ANSI Z540.3 as we go.

Calibration is an essential activity in many organizations, including test labs and manufacturing firms with precision machinery.  Back in the day, the MIL-C-45662 Calibration System Requirements ruled the day.  This original Mil Spec was replaced by the standard MIL-STD-45662 in 1980.  However with Mil Spec reform in the 1990’s, the document was cancelled in favor of the ANSI-Z540.1 and ISO-10012.

ANSI Z540.1 was titled Laboratories, Calibration, and Measuring and Test Equipment.  Released in 1994, it consisted of 2 parts — the Part 1 was based on the old ISO/IEC Guide 25 (now ISO/IEC 17025).  The Part 2 was based on the MIL-STD-45662 Revision A.  So you can see that the document was a natural successor to the old military document.  However, it was developed specifically for calibration services, not testing labs.

The Part 1 directly addressed general requirements for the competence of calibration labs.  It applied to the development and implementation of a quality system.  For some situations, these older requirements may still be used when both the customer and the lab are in agreement.

With the release of the ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories) in December 1999, there was an obvious overlap between the two standards.  In an effort to make it clear and easy for users, NCSL (the caretaker of the ANSI Z540 documents) decided to revamp the Z540 publication.  A new standard would take the place of the Part 2 while the ISO/IEC 17025 would be adopted for the material in Part 1.

The ANSI Z540.1 Part 2 addressed quality assurance requirements for a supplier’s system with regards to measurement accuracy.  This included calibration of test equipment.  It provided customers to be assured that the calibration lab was meeting the prescribed requirements.

The “new” ANSI Z540.3, Requirements for the Calibration of Measuring and Test Equipment, again establishes the technical requirements for the calibration of measuring and test equipment.  So you’ll get requirements for establishing and maintaining the performance of your measuring and test equipment.  The suitability of a calibration for the application is covered.  And the traceability of your measurement results to the International System of Units (SI) is included.

So to recap, the ANSI Z540.1 was an umbrella publication.  When the ISO/IEC 17025 was released, a new ANSI Z540.3 was issued just for the calibration requirements themselves.  The ISO/IEC document was adopted for the competence requirements.

If you need any of these publications, use Document Center Inc. for your purchase.  We have over 1 million standards for you to choose from at our webstore www.document-center.com.  Here are direct links to the order pages for ANSI Z540.3 and the ISO/IEC 17025.
