MIL-STD-740-1, Airborne Sound Measurements and Acceptability Criteria of Shipboard Equipment, inactivated for new design

MIL-STD-740-1, “Airborne Sound Measurements and Acceptability Criteria of Shipboard Equipment,” has been inactivated for new design.  If you need the inactivation notice 1, it’s available now from Document Center Inc. in either paper or pdf format.

The standard is still current for use for replacement purposes (existing applications).  However, for new design, you should use the ‘Shipboard Equipment Noise’ requirement section of MIL-STD-1474, ‘Noise Limits.’

This inactivation notice follows on the heels of the cancellation notice for the MIL-STD-740B, which we discussed in a previous blog.

All current and many obsolete Military specs and standards are available from Document Center Inc. at our website, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’re here to help you with your standards requirements and questions.

New SAE J1393 2012 Edition released, Heavy Duty Vehicle Cooling Test Code

SAE J1393, “Heavy Duty Vehicle Cooling Test Code,” has just been revised and the new J1393-2012 is available from Document Center Inc. now in either paper or pdf format.  The purpose of this SAE Recommended Practice is to establish a testing procedure to determine the performance capability of engine cooling systems, including charge air coolers, on heavy-duty vehicles with liquid-cooled internal combustion engines.

The definition of heavy vehicles for this document includes, but is not limited to, on- and off-highway trucks, cranes, drill rigs, construction, forestry and agricultural machines. Vehicles equipped with side or rear-mounted radiators may require an alternate procedure of a towing dynamometer because of peculiar aerodynamics.

Testing is generally conducted to determine compliance with cooling criteria established by the engine manufacturer or the end product user to meet a desired engine reliability goal.

SAE J1393-2012 replaces the previous edition, SAE J1393-2004, which is now obsolete.  Additionally, the document replaced SAE J819, “Engine Cooling System Field Test,” when that recommended practice was cancelled in April 2009.

SAE Standards and Recommended Practices, both current and obsolete, can be purchased from Document Center Inc. using our website, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We have been working with SAE Standards since the 1980’s and can provide you with expert assistance for the questions and requirements you may have.

New ISO 22514-7 released: Statistical methods in process management – Capability and performance – Part 7: Capability of measurement processes

There’s a new ISO 22514-7:2012, “Statistical methods in process management – Capability and performance – Part 7: Capability of measurement processes,” and it’s available now from Document Center Inc.  This new 54-page standard defines a procedure to validate measuring systems and a measurement process in order to state whether a given measurement process can satisfy the requirements for a specific measurement task with a recommendation of acceptance criteria. The acceptance criteria are defined as a capability figure or a capability ratio.

ISO 22514-7 follows the approach taken in ISO/IEC Guide 98-3, “Guide to the expression of the uncertainty in measurement (GUM),” and establishes a basic, simplified procedure for stating and combining uncertainty components used to estimate a capability index for an actual measurement process.  It was developed to be used for simple one-dimensional measurement processes, where it is known that the method uncertainty and the specification uncertainty are small compared to the implementation uncertainty.

The balance of the ISO 22514 series, “Statistical methods in process management — Capability and performance,” are:
— ISO 22514-1:  General principles and concepts
— ISO-22514-2:  Process capability and performance of time-dependent process models
— ISO-22514-3:  Machine performance studies for measured data on discrete parts
— ISO-22514-4:  Process capability estimates and performance measures
— ISO-22514-5:  Process capability and performance for attributive characteristics and
— ISO-22514-6:  Process capability statistics for characteristics following a multivariate normal distribution.

Several parts are still in process.  Part 2 and Part 6 are currently draft documents, with Part 6 due to be published soon.  Part 8 is still a committee draft and Part 5 on process capability and performance for attributive characteristics is in the works.

New AMS A 22771 Revision C released for Aluminum Alloy Forgings

The new AMS-A-22771 Revision C has just been released and it’s available now from Document Center Inc.  The standard, “Aluminum Alloy Forgings, Heat Treated,” is one of the primary plating specifications in general use, but it is valid only for replacement purposes, not for new design.

This specification covers the requirements for heat treated aluminum alloy die forgings, hand forgings, and ring forgings, produced under additional mechanical property control to ensure known mechanical properties for parts used in aerospace critical applications.  AMS-A-22771C also covers the requirements for forgings furnished in the F or 01 conditions which will ultimately be used in the heat treated condition.

The initial SAE publication of this document was taken directly from the now obsolete U.S. Military Specification MIL-A-22771D.  It retains the same part numbers established by the original military document, but requirements relating to the QPL (Qualified Products List) are not part of the SAE document.

All current SAE standards and many obsolete editions are available from Document Center Inc. in either pdf or paper format.  Order using our website, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’re here to help you with all your standards questions and requirements.

New ASME BPE, Bioprocessing Equipment, 2012 Edition now available

The critically important ASME BPE Bioprocessing Equipment standard has just been revised and the new 2012 is available from Document Center Inc. this month.  It covers, either directly or by reference, requirements for materials, design, fabrication, examination, inspection, testing, certification (for pressure systems), and pressure relief (for pressure systems) of vessels and piping for bioprocessing systems.  This includes sterility and cleanability, dimensions and tolerances, surface finish requirements, and seals for the bioprocessing systems in which the pressure vessels and associated piping are involved.

ASME BPE 2012 provides engineers and quality control professionals a measurable way to specify and purchase equipment for the Biotechnology, Pharmaceutical and Personal Care Products industries.  It is used to specify hygienic tubes, valves and fittings for use in high purity applications such as water-for-injection (WFI), clean steam, ultrafiltration, and so on.  As a result, the process of design installation, validation and maintenance can be easier to manage, leading to a reduction in overall project and maintenance costs.

This standard has proved so invaluable to the biopharmaceutical industry that it was included by reference in the 2010 California Building Code.

All current ASME standards and many obsolete editions can be purchased from Document Center Inc.  Use our website, www.document-center.com, or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  Staff is available during business hours to provide you with the standards you need, as well as management tools to keep your collection current!

New ISO 11979-1 2012 Edition for Ophthalmic implants – Intraocular lenses – Part 1: Vocabulary

ISO 11979-1, “Ophthalmic implants – Intraocular lenses – Part 1: Vocabulary,” has just been released as the new 2012 3rd Edition and is available for purchase in paper or pdf format from Document Center Inc.  This part of ISO 11979 defines terms applicable to intraocular lenses and to the methods used to evaluate them.

ISO 11979-1:2012 is an 18-page document, but ISO gives it a page count of 12 pages, since this is the number of pages with actual technical content.  The balance of the pages are considered administrative.  Additionally, this standard in unusual in that it is a dual language edition, including both English and French text on the same page.

This third edition cancels and replaces the second edition (ISO 11979-1:2006), which has been technically revised.  The ISO 11979-4:2008 has also had recent activity with the release of a new Amendment 1 for that document.  Here’s the list of the series for your review:

ISO 11979-1:  Vocabulary

ISO 11979-2:  Optical properties and test methods

ISO 11979-3:  Mechanical properties and test methods

ISO 11979-4:  Labelling and information (requires Amendment 1)

ISO 11979-5:  Biocompatibility

ISO 11979-6:  Shelf-life and transport stability

ISO 11979-7:  Clinical investigations (requires Amendment 1)

ISO 11979-8:  Fundamental requirements (requires Amendment 1)

ISO 11979-9:  Multifocal intraocular lenses

ISO 11979-10:  Phakic intraocular lenses

New ASTM D882 2012 Edition, Standard Test Method for Tensile Properties of Thin Plastic Sheeting

ASTM has just released the new ASTM D882-12, “Standard Test Method for Tensile Properties of Thin Plastic Sheeting,” and it’s available now from Document Center Inc.  The tensile modulus of elasticity is an index of the stiffness of thin plastic sheeting.  Tensile tests measure the force required to break a specimen and the extent to which the specimen stretches or elongates to that breaking point.

Tensile properties determined by ASTM D882 are of value for the identification and characterization of materials for control and specification purposes. Tensile properties can vary with specimen thickness, method of preparation, speed of testing, type of grips used, and manner of measuring extension. Consequently, where precise comparative results are desired, these factors must be carefully controlled.

The new 2012 Edition cancels and replaces the previous ASTM D882-10 Edition.  The ASTM standard is similar to ISO 527-3 , but is not considered technically equivalent.  ISO 527-3  allows for additional specimen configurations, specifies different test speeds, and requires an extensometer or gage marks on the specimen.

Both ISO and ASTM standards are available from Document Center Inc., an authorized reseller of standards, at our website www.document-center.com.  Or feel free to contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We are able to assist you with your standards purchases and questions during our business hours, 8 am to 5 pm Monday through Friday, Pacific (California) Time.

New Revision A available for popular A-A-208 on Opaque Marking Ink

A-A-208, “Ink, Marking, Stencil, Opaque (Porous and Non-Porous Surfaces),” has just been revised and the new Revision C is available from Document Center Inc. now.  The Commercial Item Description covers four types of opaque ink for marking on porous and non-porous surfaces and has not been updated since 1995.

Classification in the new A-A-208C covers 4 types and 2 Classes:

Type I – For Use on Non-Porous Surfaces (Non-Pressurized Containers)
Type II – For Use on Porous Surfaces (Non-Pressurized Containers)
Type III – For Use on Non-Porous Surfaces (Pressurized Containers)
Type IV – For Use on Non-Porous Surfaces (Stencil Rollers)

Class A – Standard formulation stencil ink
Class B – Stencil Ink formulated free of Hazardous Air Pollutants (HAP-free)

In reviewing the two documents, I note that the most obvious change is the inclusion of the new Class B for HAP-free Stencil ink.  And since the address for ASTM is incorrect in the new document, I forwarded a note to my contacts at the DoD and ASTM.  I wouldn’t be surprised if an amendment is released shortly with the corrected address.

This ink specification is a commonly used document.  It’s a Commercial Item Description, which is marked by the use of the “A-A” at the head of the document number.  The document describes an item that can be purchased in the “open market,” called a Commercial Item in U.S. government purchasing parlance. General examples of commercial items the government buys range from food, clothing, and computers to trucks and airplanes. The availability of commercial items to meet a specific defense requirement is determined by market research.

So Commercial Item Descriptions describe any item that has been sold, leased, or licensed to the general public or that has been offered for sale, lease, or license to the general public. This would include offerings from wholesale and retail distribution centers, catalogs, and personal sales, as well as items that have been offered for sale but not yet purchased.

All Federal Specifications, including the Commercial Item Descriptions, are available from Document Center Inc. at our website, www.document-center.com.  Or you can contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We have an extensive collection of current and obsolete revisions available.

New ISO/IEC 17065, Conformity assessment – Requirements for bodies certifying products, processes and services

There’s a new ISO/IEC 17065, “Conformity assessment – Requirements for bodies certifying products, processes and services,” and it’s available now from Document Center Inc. This 34-page first edition of ISO/IEC 17065 cancels and replaces ISO/IEC Guide 65:1996, which has been technically revised.

The overall aim of certifying products, processes or services is to give confidence to all interested parties that a product, process or service fulfills specified requirements. The value of certification is the degree of confidence and trust that is established by an impartial and competent demonstration of fulfillment of specified requirements by a third party.  Interested parties can expect or require the certification body to meet all the requirements of ISO/IEC 17065:2012 as well as, when relevant, those of the certification scheme itself.

The following major changes have been made compared with ISO/IEC Guide 65:1996, “General requirements for bodies operating product certification systems:”

  • restructuring of this International Standard based on the common structure adopted by ISO/CASCO,
  • modifications based on ISO/PAS 17001, ISO/PAS 17002, ISO/PAS 17003, ISO/PAS 17004 and ISO/PAS 17005,
  • introduction of the ISO/IEC 17000 functional approach in the process requirements of Clause 7,
  • information on the application of this International Standard for processes and services in Annex B,
  • revision of the terms and definitions in Clause 3,
  • improvement of the impartiality requirements (mechanism),
  • consolidation of the management system requirements in Clause 8,
  • inclusion of principles for product certification bodies and their activities in Annex A,
  • improvement by taking into account IAF GD 5:2006 “Guidance on ISO/IEC Guide 65:1996,” and
  • inclusion of a reference to certification schemes, for which further information is provided in ISO/IEC 17067, “Conformity assessment — Fundamentals of product certification and guidelines for product certification schemes,” which is currently under development.

All ISO, IEC, and ISO/IEC standards are available from Document Center Inc. on our website, www.document-center.com.  Or you may prefer to contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We have been selling these standards under a license agreement since the 1990’s and offer complete standards support services as well.

A new Standards War is brewing between SAE J1772 and CHAdeMO for charging Electric Vehicles

Here in the San Francisco Bay Area, we pride ourselves on being forward thinking and actively green!  And that means we’re early adopters of new automotive technologies for hybrid and all-electric vehicles.  Indeed, Tesla developed their first electric cars in our neighborhood before moving to Palo Alto just down the street and our general region boasts over 500 electric charging stations.  So when the San Jose Mercury brought the brewing Standards War between the SAE J1772:2012 and CHAdeMO, I was immediately interested.

At first blush, it looks like a skirmish between the Asian (Japanese) automakers and those in the U.S. and Europe.  The fight is over the type of plug used when quick charging battery powered electric vehicles.

The CHAdeMO standard was developed by an industry consortium formed by TEPCO (the Japanese Power Company) and four automakers (Nissan, Mitsubishi, Subaru’s parent company and Toyota).  TEPCO makes the DC connector for quick charging and three of the four automakers have developed battery powered cars so far.  Of course, TEPCO has developed patented technology and a specification for high-voltage, high-current automotive fast charging that looks to be the basis for the standard.

In the meantime, the SAE International (formerly the Society for Auromotive Engineering)  J1772 has been around since 2001 (the latest revision is from February, 2012).  It’s no surprise to me that the development of the original standard was driven by the California Air Resources Board.  I lived in Los Angeles for a while back in the 1980’s and air quality has been an issue in this state for a very long time…

The SAE Recommended Practice covers the general physical, electrical, functional and performance requirements to facilitate conductive charging of electric vehicles in North America. This document  includes operational requirements and the functional and dimensional requirements for the vehicle inlet and mating connector.

And it is the connector that is at the root of this battle.  Two different, competing standards with two different, competing connectors.  And since we have the investment in charging stations starting already, we’re sure to have confusion when early adopter car owners go to “fill ‘er up!”

Sadly, there’s still more ways to charge your new Electric Vehicle than even these two competing standards.  Tesla (a home town favorite, I admit) has taken to developing it’s own charger.  And VDE (Association for Electrical, Electronic and Information Technologies) in Germany also has a standard that is used by the makers of a number of European prototypes and that has been submitted to IEC for adoption as an International Standard.

Here in California, we’re hedging our bets, with the state of California installing fast-charging stations that support both CHAdeMO and the SAE fast-charge system.  And the Nissan Leaf similarly has the connector for both chargers.

Meantime, this has gotten me interested in Standards Wars, so expect more blogs in the future on the topic.  Meantime, we have all SAE standards (including SAE J1772) for sale on the Document Center website, www.document-center.com.  And you’re welcome to contact us at any time by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’re here to assist you with your standards questions and requirements.
