New ANSI/ESD S20.20 – ESD Protection for Electronic Parts

September 8th, 2014

ANSI/ESD S20.20 is one of Document Center’s best-selling ESD protection standards.  Titled “Protection of Electrical and Electronic Parts, Assemblies and Equipment (Excluding Electrically Initiated Explosive Devices),” it’s just been updated with the release of a new 2014 Edition.  The standard is part of the ESD Association’s series on the Development of Electrostatic Discharge Control Programs.  It specifically addresses how to set up and maintain an ESD control program for dealing with electronic parts and assemblies susceptible to damage from discharges greater than or equal to 100 volts Human Body Model (HBM) or 200 volts Charged Device Model (CDM).

As a user of the ANSI/ESD S20.20, you’ll be wondering what the changes are in this new 2014 Edition.  Here’s a listing of the areas the committee has brought to your attention in the Annex D concluding material of the new revision:

  • the Scope Section has been expanded to add voltages to applicable  isolated charged conductors
  • Section 6.1 has been modified
  • in Section 7.1, Product Qualification has been added as an element of the ESD Control Program Plan, resulting in the addition of a new Section 7.3 and further renumbering of other Section 7 subsections
  • Section 8.2 has been updated
  • Section 8.3 now has additional requirements and Table 3 has been modified
  • Section 8.4 on packaging has been reworded for clarity
  • Annexes A and B have also been updated

New MIL-STD-101 C – Colors for Gas Pipelines and Cylinders

September 4th, 2014

The MIL-STD-101, “Color Code for Pipelines and for Compressed Gas Cylinders,” is used for the paints and coatings on piping systems and cylinders for gas.  It covers a common color code system and has not been revised since 1970.  However, the “de-commissioning” of the FED-STD-595 and the move to the use of the CIELAB color system instead has initiated a review of this document.  Which means there’s just been the release of a new Revision C for this standard.

Good news for all you MIL-STD-101 users — the new Revision C is clearly marked in the margins where changes have occurred.  However, there’s a lot of black margin lines in this new release!

You’ll note that medical gases have been removed from the MIL-STD-101C.  (FYI:  They’re now covered by the NATO Standard AMedP-53.)  Also, there’s been a number of new “assignments” since 1970 and these new materials are now included in the standard.  The ANSI Z48.1 references have been replaced by references to the CGA C7 standard instead, “Guide to the Preparation of Precautionary Labeling and Marking of Compressed Gas Containers.”  And there’s clarification regarding the need for adherence to the Department of Transportation regulations for required marking and stamping when applicable.

If you provide the Department of Defense with gas piping, gas cylinders, or gas transport systems, you’ll need a copy of the new document.  Consider using Document Center as your source for your government publications like this one.  You’ll find it easy to order at our webstore,  Or you can contact us by phone (650-591-7600), fax (650-591-7617, or email (  You can get your copy in paper format, as a pdf download, or for multi-user access with our Standards Online subscription service.

MIL-STD-348 updated!

August 29th, 2014

MIL-STD-348, “Radio Frequency Connector Interfaces for MIL-DTL-3643, MIL-DTL-3650, MIL-DTL-3655, MIL-DTL-25516, MIL-PRF-31031, MIL-PRF-39012, MIL-PRF-49142, MIL-PRF-55339, MIL-DTL-83517,” has just been revised.  This is a Department of Defense Interface Standard and provides the user with the dimensional requirements for the specified connector interfaces.  The new Revision B is a complete overhaul of the standard.  The previous Revision A (now obsolete) was last modified by Notice 6 in 2003.

The first 5 pages of the standard cover the usual requirements – scope, referenced documents, definitions and so on.  The real bulk of the document is in the various  sections, one for each of the Military Specifications referenced in the title.  Each section includes figures for the related series of RF connectors, with complete interface diagrams.  There are also tables which provide you with the dimensions for each, specified by dimension letter.

Since the MIL-STD-348 B is 222 pages long, you can see that it contains a wealth of information necessary for correctly fulfilling contracts that make use of the applicable Military Specifications.  It’s a major re-write of the previous edition so there are no lines in the margins to identify where changes have occured.  You’ll have 12 months from the issue date of the standard to comply with the new requirements.

Many of our Document Center electronics and defense industry customers use this standard.  Why have they purchased their copy from us?  For one reason, we give them the option of purchasing the document in paper format, for pdf download or as part of our multi-user Standards Online service.  And we provide them with a number of ways to confirm that they’re using the correct edition and changes, including our superior notification service.

ISO/TS 17929 – Passenger Safety on Amusement Rides!

August 28th, 2014

The three-day weekend is coming and I bet any number of you will spend a day (or more) at an amusement park!  Of course, passenger safety is a top concern but one that you won’t have to think about since there’s strong standardization in this area.  And the new ISO/TS 17929, “Biomechanical effects on amusement ride passengers,” is providing additional support — specifically addressing the biomechanical effects that makes those rides so much fun!

Indeed, it’s the emphasis on biomechnical effects that makes amusement rides so different than other types of conveyances.  But hey, this means that when you get on  one of these rides, you’re subject to inertia forces — and sometimes those forces can result in risks.  So the ride designers will need to consider and minimize the risks and maximize the fun.

After the usual scope, definitions, and referenced document sections, the ISO/TS 17929 specification focuses in on 4 areas for design consideration:

  • Potential biomechanical risks
  • Elimination or reduction of those risks
  • Effects of accelerations on passengers
  • Zones where potential risk occurs, including unscheduled braking and so on

Four informative annexes cover body dimensions to be used during motion risk analysis, recommended acceleration limits, hazards for passengers being held up-side-down, and the use of warning signs to advise passengers, including state of health considerations.

This document will eventually work in tandem with a proposed ISO 17842 series on the safety of amusement rides and amusement devices.  It’s intended to have a number of parts, but there’s no scheduled dates or further information on the development of this series of documents.

If you’re in the amusement rides business, you’ll want to review this specification for use in future development.  You can get your copy by order it in paper format or for pdf download from the Document Center webstore at  Or contact our staff by phone (650-591-7600), fax (650-591-7617) or email (

New NFPA 79 – Electrical Standard for Industrial Machinery

August 27th, 2014

The NFPA 79, “Electrical Standard for Industrial Machinery,” is a consistently requested standard here at Document Center Inc.  It is used in environments with industrial machinery to protect against fire and electrical hazards.  It applies to electrical and electronic equipment using a nominal voltage of 600 volts or less.  Requirements start at the point of connection of the power supply and continue through to the electrical equipment of the machine.  And there’s new 2015 Edition is available now!

Since the last revision in 2012, there have been a number of changes to the standard.  They include:

  • Harmonizing the requirements with IEC 60204-1.
  • Updating Section 6.6 on Arc Flash Hazard Warning to bring it in line with the National Electrical Code (NEC) Section 110.16.
  • Revising Category 1 and Category 0 conditions for “emergency stop” and “emergency switching off.”
  • Clarification of the rules when separate supply sources are used.
  • Harmonization of working space rules for enclosures that contain supply conductors to match the NEC Section 110.26.
  • Updating the width of the working space to include that of the opening into the control cabinet.

Who should be using the NFPA 79?  This standard is essential for safety managers, electrical designers, engineers, installers, owners, and industrial machinery manufacturers.

What’s covered by NFPA 79?  The standard spells out essential protection for operators, equipment, facilities, and work-in-progress.  And you’ll find examples of industrial machines covered in Annex C, if you’re interested.

What conditions are not covered by NFPA 79?  It does not include the additional requirements for machines intended for use in hazardous (classified) locations.

How can you get your copy of the new 2015 Edition?  Order at the Document Center webstore,  Or contact our staff by phone (650-591-7600), fax (650-591-7617) or email (  We’ve been providing our customers with standards from our Silicon Valley location since 1982.  And we have a wide variety of support services and products to help you use these conformance documents as well.  Make us your Standards Experts!

New IPC-A-610 F coming soon!

August 26th, 2014

IPC-A-610, “Acceptability of Electronic Assemblies,” is the workhorse of the Electronic Assembly standards.  Now there’s a new Revision F for this standard and you can pre-order your copy now from Document Center Inc.  This is the most widely used electronic assembly standard in the world, and if you’re one of the many who rely on it, you’ll want the new edition as soon as possible.

One of the main drivers of this update was the desire to harmonize the content of the IPC-A-610 with the J-STD-001 (which is also updating to a new Revision F now as well).  There’s also been an effort to gain synergy with additional Mil Standards and the IPC-A-620 too.  This has resulted in a number of updates to the Clauses in Section 6 of the IPC-A-610 and Section 5 of the J-STD-001.  You’ll also find similar revision to Section 8 of the IPC-A-610 and correspondingly the Section 7 of the J-STD-001.

The committees for the  two standards have really taken user input into account for these updates, as is the protocol for good standards management.  All comments have been reviewed and action taken as necessary.  If you were one of those who submitted comments on the IPC-A-610, you’ll be pleased that your concerns were heard.

Of course, even though the IPC-A-610 Revision F is approved, there is still the time lag associated with publication.  So this means that release from the printers on this item is not expected until next month.  Meantime, you’ll want to know that you’ll get your copy of the new revision as soon as possible.

Go ahead and order your copy now from Document Center Inc.  The price will remain the same as for the Revision E, and the update is available in paper format, as a CD Rom or as a kit with both the paper and CD Rom included.

You can use the Document Center webstore,, or you can contact our staff by phone (650-591-7600), fax (650-591-7617) or email (  We’ve been an authorized dealer of the IPC standards for many years, supplying our customers with the IPC publications from our Silicon Valley location.  If you’re in the electronics industry, you’ll want to make Document Center Your Standards Experts!

New ISO 8124-6 – Toy Safety – Phthalate esters

August 21st, 2014

Toy safety is a top concern and over time the standards in this area have gained wide acceptance.  Concurrently, regulatory requirements have multiplied, providing manufacturers with the challenging task of meeting diverse requirements for products with a short shelf life.  Now to assist in meeting conformity assessment requirements, ISO 8124-6, “Safety of toys – Part 6: Certain phthalate esters in toys and childrens products,” has been released.  Based on the GB/T 22048 (available in Chinese language only), the standard does not set limits for the inclusion of phthalate esters.  Rather it provides you with a method for determining how much of the various kinds of phthalate esters exist in toys and children’s products.

Phthalate esters themselves are used in plastics to provide greater flexibility and improved ability to hold color and/or fragrance.  They actually have a weak bond, so they are one of the major plastics pollutants in the environment.  Although they have not been shown to be toxic, there is concern that over time exposure can have negative effects (both developmental and reproductive).  Because of this, various jurisdictions have enacted regulatory limitations on the inclusion of these substances in children’s products.

As a toy manufacturer or distributor, you’ll rely on the use of the ISO 8124-6 to test your product(s).  It’s basically a process when a small piece of the item is processed for determination of phthalate esters both qualitatively and quantitatively by gas chromatograph-mass spectrometry.   The standard covers the reagents, apparatus, selection of the test portion and the procedure, calculation, quality control, precision and the test report itself.

There are an additional six Annexes.  Annex A contains the only required material — A table of the various kinds of phthalate esters themselves.  While the remaining five Annexes are informative, they are actually quite technical and provide essential information for the successful use of the standard.  A 12-item bibliography finishes out the document.

The new ISO 8124-6 is the 5th part of the series to be published.  The balance of the series (both available and in process) are:

  • ISO 8124-1, Safety of toys – Part 1: Safety aspects related to mechanical and physical properties
  • ISO 8124-2, Safety of toys — Part 2: Flammability
  • ISO 8124-3, Safety of toys Part 3: Migration of certain elements
  • ISO 8124-4, Safety of toys — Part 4: Swings, slides and similar activity toys for indoor and outdoor family domestic use
  • Proposed ISO 8124-5, Safety of toys — Part 5: Determination of total concentration of certain elements in toys
  • Proposed ISO 8124-7, Safety of toys — Part 7: Requirements and test methods for finger paints
  • ISO/TR 8124-8 (Just released!), Safety of toys — Part 8: Age determination guidelines

You’ll need a copy of the new ISO toy safety standard, and you can purchase an authorized copy from Document Center Inc.  You’ll have the option of getting it in paper format, as a pdf download, or for multi-use access in our Standards Online subscription service.  Order through our website,  Or contact our staff by phone (650-591-7600), fax (650-591-7617) or email (
