New TAPPI T410 2013 Edition on Weight of Paper and Paperboard

There is a new TAPPI T410 2013 Edition, “Grammage of paper and paperboard (weight per unit area),” released at the end of April.  You can get the updated revision from Document Center Inc. in both paper and downloadable pdf formats now.  It’s an important standard because most paper is bought and sold in accordance with its mass per unit area.

TAPPI T410 defines the ratio that is the basis for the cost of paper and paperboard.  It is also used to determine the values of many physical properties such as bursting strength, thickness, and bulk, and the calculation of many strength properties.

Even though we in the U.S. are accustomed to expressing the ‘weight’ per unit area (really “mass per unit area”) of paper as basis weight, ream weight or substance, the use of the word ‘grammage’ is recommended by the ISO committee TC6 on Paper.  This term is being used because it more correctly reflects the metric grams per square meter, which is becoming the industry norm.

It used to be that the weight ratio for paper was determined by the use of a ream of a given sheet size (occasionally 480 sheets instead of 500).  The weight in pounds would be the calculated leading to the classification for the paper.

Because TAPPI favors the metric system, SI ‘grammage’ (mass per unit area) is the unit of choice for all TAPPI standards.  This means the area of several sheets of the paper or paperboard is determined from linear measurements and the mass is determined by weighing. Then grammage is calculated from the ratio of the mass to the area after conversion to metric units if necessary.

As with the 2008 Edition, this revision contains minor editorial corrections.  The ASTM D646 has been withdrawn as a related method, since it has been cancelled.  The ISO 536 continues to be referenced.

All TAPPI standards are available for purchase in paper format or as downloadable pdf documents from Document Center’s web store, www.document-center.com.  You can also check in with us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’re customer friendly, happy to discuss your questions and requirements whenever you need assistance.

New MIL-PRF-46846 Revision D released for Heat-Shrinkable Tubing

There’s a new MIL-PRF-46846 Revision D, “Rubber, Synthetic, Heat – Shrinkable,” available from Document Center Inc.  You can purchase the document in both paper and pdf format.  The specification covers the type and class requirements for heat-shrinkable rubber extruded tubing, shapes, and molded parts.

These products are flexible, electrical insulating and have dimensions that will shrink to a predetermined size when heated. The heat-reactive synthetic rubber material is used in a wide range of applications  requiring a tough, flexible synthetic rubber that will maintain good physical and electrical properties after heat shrinkage.

Such products are used for identification and covering splices in cables, lugs, and pipes, protecting feed-throughs, jacketing assemblies, insulating pigtail connections, as sleeves for wave guides and rectifier leads, and as covers for resistors and diodes.

MIL-PRF-46846 has unique military requirements because some types and classes must be resistant to chemicals such as hydrazine/UDMH (MIL-PRF-27402), Dinitrogen tetroxide (MIL-PRF-26539) and nitric acid (MIL-PRF-7254) (propellants in missiles.)  All types must be resistant to fuels and oils such as JP-4 fuel, hydraulic fluid (MIL-PRF-5606), lubricating oil (MIL-PRF-7808) and aviation gasoline 100/130 – all used on military aircraft. And all types must be functional over military temperature ranges, which exceed that required in the commercial market.

There are a lot of changes in the new revision.  For example, Type I Class 1 has been deleted because it duplicates AMS-3623.  And Type V is replaced by AMS-DTL-23053/5.  Another interesting development is the acceptance of metric equivalents when generated per FED-STD-376.

Document Center sells a complete catalog of Mil Specs and Standards, Fed Specs and Standards, and SAE publications at it’s web store, www.document-center.com.  You can search, find and buy the documents (including obsolete revision levels) at our site.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We have been selling standards since 1982 and can assist you with all your documentation requirements.

New ISO/TS 17665-3 released for Steam Sterilization of Medical Devices

A new technical specification, ISO/TS 17665-3, “Sterilization of health care products – Moist heat – Part 3: Guidance on the designation of a medical device to a product family and processing category for steam sterilization,” has just been issued.  The new specification is the 3rd part in this series on efficient sterilization of medical devices and is meant to be used with Parts 1 and 2.

In most health care facilities, sterilization of medical devices and health care products is done by the steam sterilization method.  It consists of three distinct stages:  air removal, sterilizing and drying.

This standard is  intended to assure sterilization when multiple products are processed at the same time.   This “sterilization load” is made safe by processing product families that have been pre-screened using the ISO/TS 17665-3 standard methodology.

ISO/TS 17665-3 helps the user define the attributes of the device for assigning a product family category for the moist heat sterilization process.  These attributes have been chosen based on operation experience, engineering considerations and experimental data.  They rely on the types and designs of differing medical devices and sterile barrier and/or packaging systems.

The three documents that make up the series are:

  1. ISO 17665-1:2006, Sterilization of health care products — Moist heat — Part 1: Requirements for the development, validation and routine control of a sterilization process for medical devices
  2. ISO/TS 17665-2:2009,  Sterilization of health care products — Moist heat — Part 2: Guidance on the application of ISO 17665-1, and
  3. ISO/TS 17665-3:2013, Sterilization of health care products – Moist heat – Part 3: Guidance on the designation of a medical device to a product family and processing category for steam sterilization

You can purchase ISO standards, both current editions and many obsolete revisions, at Document Center’s web store, www.document-center.com.  Or you can reach us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’re Your Standards Experts and we’re here to make sure you have the standards you need to run your business effectively.

New ASTM C1009 2013a Edition released for Nuclear Industry Labs

We’ve just received the new ASTM C1009 2013a Edition, “Standard Guide for Establishing and Maintaining a Quality Assurance Program for Analytical Laboratories Within the Nuclear Industry.”  The Guide covers the establishment and maintenance of a quality assurance (QA) program for analytical laboratories within the nuclear industry.

These types of labs provide services for many types of applications, including geological prospecting, environmental contamination survey or biomedical investigations.  The ASTM C1009 is part of an international effort to assure  customers of these labs that the results of any given analysis is globally recognized in order to facilitate to movement of goods in cross-border trade.

So while the Guide does not have the language that supports manditory adherence to its various clauses, an analytical lab of this type must meet stringent requirements for each of the elements addressed in the document.  These elements are Organization, Quality Assurance Program, Training and Qualification, Procedures, Lab Records, Control of Lab Records, Control of Procurement, Control of Measuring Equipment and Material, Control of Measurements, and lastly, Deficiencies and Corrective Actions.

ASTM C1009-13a is one of 4 core documents for quality assurance in laboratories that provide quality analyses on nuclear fuel cycle materials.  The other three standards are the ISO 9001, of course, ISO/IEC 17025 and ASME NQA-1, which has also been recently updated.  Table X1.1 cross-references the requirements of all 4 publications.

You can buy all ASTM standards, as well as the other documents mentioned, at Document Center’s web store, 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 selling standards since 1982 and can assist you with all your standards requirements and questions.

 

New ASTM F2989 covers Unalloyed Titanium Components Used for Surgical Implants

There’s a new ASTM F2989 2013 Edition, “Standard Specification for Metal Injection Molded Unalloyed Titanium Components for Surgical Implant Applications.”  The document covers the chemical, mechanical and metallurgical requirements for three grades of metal injection molded unalloyed titanium components to be used in the manufacture of surgical implants.

The metal injection molded (MIM) titanium in ASTM F2989-13 makes use of 2 types as well as the 3 grades.  The chemical composition matches up to ASTM F67 except for the maximum oxygen level of Grade MIM 3.

The standard provides for both the use of SI (preferred) and inch-pound units without the use of the ASTM F2989/F2989M designator.  This is because ASTM is in the process of implementing a migration path that should culminate with total reliance on SI units by 2018.

Another thing to note in ASTM F2989 is the Appendix X2 on biocompatibility.  It is informational and provides the user with a basis for evaluating the level of biological response to be expected when using this material.  Appendix X1 – Rationale – includes the purpose;  chemistry, process history and mechanical properties; fatigue; binders; and units of measurement.

ASTM F2989 was developed not only for manufacturers and medical device companies, but also to serve as a basis for certification by testing laboratories and as a guideline for regulatory bodies.  It supports the design of new shapes and allows MIM components to be directly compared to parts made by more conventional methods.

The 2013 Edition is an update of the ASTM F2989 2012 Edition.  For the details on the changes, you’ll want to purchase the redline edition.  This comes with a clean copy of the 2013 revision plus a copy of the 2012 document with the changes marked clearly for your review.

You can order ASTM Standards in both paper and pdf format from Document Center at our web store, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We are your Standards Experts and we’re here to help you keep your conformance documentation complete and current.

MIL-DTL-22520 Group Cancellation issued for Crimping Tools

A group cancellation notice has been issued for MIL-DTL-22520 and four  of it’s slash sheets.  The documents are all for wire termination crimping tools and all have been replaced by the AS 22520 editions of the same specifications.  Both the obsolete Mil specs and the replacement AS documents can be purchased from Document Center Inc. in both paper and pdf format.

Here’s the details:

  • MIL-DTL-22520, Revision G, “Crimping Tools, Wire Termination, General Specification for,” has been withdrawn in favor of AS 22520, same title, issued by SAE in 2011
  • MIL-C-22520/17 Revision B, “Crimping Tools, Terminal, Hand, Wire Termination for Crimp Type Removable Contacts, Electric Connectors,” has been withdrawn in favor of AS 22520/17, again same title and again issued in 2011
  • MIL-DTL-22720/38, “Crimping Tool, Terminal, Hand Actuated, Wire Termination, Type II, for External Power Plug Socket Contacts and Lug Terminal Sizes 22-10,” has been withdrawn and replaced by AS 22520/38, same title, same year.
  • MIL-DTL-22720/40, “Crimping Tools, Terminal, Hand, Wire Termination; Type II T-Head for Terminal Lugs and Splices Size 22-14,” has been withdrawn in favor of AS 22520/40, same title, issued in 2012.
  • MIL-DTL-22720/41, “Crimping Tools, Terminal, Hand, Wire Termination; Type II for Terminals and Splices Size 10-14,” replaced by AS 22520/41, with the same title and issued in 2012 as well.

FYI: The DoD has issued a notice of adoption for each of the AS replacement documents.  This adoption notice states that the industry standard has been reviewed and is authorized for use in military contracts.

It is typical in these cases for the latest edition of the military document to be reprinted as is, with modifications made to meet the differing SAE format requirements.  Over time, the AS reprints may be revised and that signals the participation of the DoD in the committee process itself.

Purchase your copies of these specifications at Document Center’s web store, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com) to learn more about these items.  We’ve been reselling both collections since the 1980’s and have the expertise to assist you with any requirements you may have.

New IEEE 4 2013 Edition for High Voltage Testing Techniques

There’s a new IEEE 4, “IEEE Standard for High-Voltage Testing Techniques,” that’s just been released.  The standard is one of the oldest titles in the IEEE collection, with the first edition dating back to 1928.  This new 2013 update is the 8th Edition.

IEEE 4-2013 establishes standard methods and basic techniques for high-voltage testing. The standard is applicable to all types of apparatus for alternating voltages, direct voltages, lightning impulse voltages, switching impulse voltages, and impulse currents.  It is applicable only to tests on equipment with a rated voltage above 1000 V.

IEEE 4 is intended to define terms of general applicability, provide general requirements for test equipment and procedures, and to describe various methods for the evaluation of the test results.  You’ll find procedures for applying correction factors to convert test data to standard atmospheric conditions.  And methods are supplied for testing equipment when external insulation of the test object is to be subjected to dry, wet, or contaminated conditions.

There is no guidance in the document itself for determining exactly where changes have been made.  However, the revision has reorganized the technical content so that the sections that deal with alternating voltage, direct voltage, and impulse voltage testing are grouped together.  Also, it introduces the concept of measurement uncertainty in evaluation of high-voltage and high-current tests.

The previous 7th Edition was issued in 1995 but of course it was made obsolete with the release of the 2013 revision.

All IEEE standards are available from Document Center’s web store, www.document-center.com, in either paper or pdf format.  We carry both current and obsolete editions.  If you prefer, contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’d be happy to assist you with all your conformance documentation requirements.

New Revisions Released for MIL-STD-750 series

MIL-STD-750, “Test Methods for Semiconductor Devices,” and several of it’s subsections have recently been updated.  Compliance with the changes is expected to be completed by June 13, 2013.

MIL-STD-750F is modified by the new Change 1.  It is the overview document for the series which establishes uniform test methods for testing the environmental, physical, and electrical characteristics semiconductor devices.  The change notice adds paragraph 4.1.3, to define acceptable international sinusoidal pulse input wave frequency.

MIL-STD-750-1 covers Environmental Tests 1000 through 1999.  The change notice 1 is more extensive, modifying paragraphs 13, 13.1.1, 13.1.2, and 13.2.1 (all part of Test Method 1071).

For MIL-STD-750-2, Mechanical Test Methods 2001 through 2999, the new update is Change 3.  This change modifies several test method in order to bring them in line with MIL-STD-883.  The test methods that have been changed are 2006 (paragraph 3), 2056 (paragraph 3.2.2), and 2057 (paragraphs 3.3 and 3.4).

All of these updates are released as interfiled editions.  This means that the standard plus all changes is republished in 1 document, with the changed language already included.  It is helpful in that the user doesn’t have to make the changes by hand, but it can sometimes make the identification of changes more difficult.  In the case of the MIL-STD-750 series, the summary of changes at the beginning of the revised documents is most helpful.

MIL Standards and Specifications can all be purchased from Document Center Inc. in paper or pdf format at our webstore, www.document-center.com.  Or consider reaching us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’re here to assist you with all your requirements for keeping your compliance collection complete and correct.  We’re your Standards Experts!

EN 1760-1 and EN 1760-2 replaced by ISO 13856 adoptions

If you use EN 1760-1, “Safety of machinery. Pressure sensitive protective devices. General principles for the design and testing of pressure sensitive mats and pressure sensitive floors,” or EN 1760-2, “Safety of machinery. Pressure sensitive protective devices. General principles for the design and testing of pressure sensitive edges and pressure sensitive bars,” the documents have been withdrawn.  You’ll want to replace your copies with the EN adoptions of ISO 13856-1 and ISO 13856-2 respectively.

The new adoptions are:

  • BS EN ISO 13856-1:2013, “Safety of machinery. Pressure-sensitive protective devices. General principles for design and testing of pressure-sensitive mats and pressure-sensitive floors.”  The new adoption establishes general principles and specifies requirements for the design and testing of pressure-sensitive mats and pressure-sensitive floors normally actuated by the feet for use as devices for protecting persons from hazardous machinery. The minimum safety requirements for the performance, marking and documentation are given.
  • BS EN ISO 13856-2:2013, “Safety of machinery. Pressure-sensitive protective devices. General principles for design and testing of pressure-sensitive edges and pressure-sensitive bars.”  This standard is applicable to pressure-sensitive edges and pressure-sensitive bars, with or without an external reset facility, used to detect persons or body parts that can be exposed to hazards such as those caused by the moving parts of machines.

EN 1760-3 remains current.

The source standards, ISO 13856-1 and ISO 13856-2, were both revised this year.  They are classified as Type-B2 standards on safeguards (e.g. two hand controls, interlocking devices, pressure sensitive devices, guards).  It is not clear from a reading of the two ISO standards how they were modified to accommodate adoption as European Standards.

All current ISO and BS EN standards can be purchased under license agreement from Document Center’s web store, 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 questions and requirements for the compliance documentation you need to use in your business.
