BS EN 71-2, “Safety of toys. Flammability,” has just been released as the new 2011 Edition. It replaces BS EN 71-2:2006+A1:2007, which is now obsolete. This official English edition specifies the categories of flammable materials which are prohibited in all toys sold in Europe, and requirements concerning flammability of certain toys when they are subjected to a small source of ignition.
The test methods described in Clause 5 are used for the purposes of determining the flammability of toys under the particular test conditions specified. The test results thus obtained cannot be considered as providing an overall indication of the potential fire hazard of toys or materials when subjected to other sources of ignition.
BS EN 71-2:2011 includes general requirements relating to all toys and specific requirements and methods of test relating to the following toys, which are considered as being those presenting the greatest hazard: - toys to be worn on the head: beards, moustaches, wigs, etc. made from hair, pile or material with similar features; masks; hoods, head-dresses, etc.; flowing elements of toys to be worn on the head, but excluding paper novelty hats of the type usually supplied in party crackers; - toy disguise costumes and toys intended to be worn by a child in play; - toys intended to be entered by a child; - soft-filled toys.
NOTE Additional requirements for flammability of electric toys are specified in BS EN 62115.

ASTM E84-11a, Standard Test Method for Surface Burning Characteristics of Building Materials, has just been released on the heels of the E84-11 update. This is a situation that occasionally occurs with the ASTM standards. It’s due to the fact that each modification of an ASTM standard results in a new revision being released.
The ASTM E84-11 was approved on 6/15/2011. It had a number of corrections — The addition of paragraph 6.9, the addition of figure 6 and the corresponding renumbering of the following figures, and the removal of paragraph X1.6 in Annex X1 with the corresponding renumbering of the following paragraphs as well.
However, shortly after the approval, two subsequent corrections were found, resulting in the acceptance of revision E84-11a on 7/1/2011. These two additional fixes are the correction of the title of the reference to ASTM E2688 and the addition of a reference to ASTM E2690.
This fire-test-response standard for the comparative surface burning behavior of building materials is applicable to exposed surfaces such as walls and ceilings. The test is conducted with the specimen in the ceiling position with the surface to be evaluated exposed face down to the ignition source. The material, product, or assembly shall be capable of being mounted in the test position during the test. Thus, the specimen shall either be self-supporting by its own structural quality, held in place by added supports along the test surface, or secured from the back side.
The purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke developed index are reported. However, there is not necessarily a relationship between these two measurements.
This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.
All ASTM standards, including obsolete revisions, can be purchased from Document Center Inc. Many are available in redline editions, which allow you to review the specific changes from one edition to the next. Use our website, www.document-center.com, to order. Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).

AMS-C-26074 Cancellation Revision C has just been issued. Titled “Electroless Nickel Coatings,” the specification covers the requirements for electroless (autocatalytic chemical reduction) deposition of nickel-phosphorous alloy coatings on metal and composite surfaces.
The document replaced MIL-C-26074 for all users except for NAVSEA Nuclear personnel. With this cancellation, users are directed to AMS-2404 for replacement purposes and AMS-2404 or AMS-2433 for new design. The table on the first page of the cancellation revision lists the correlation information to match the classes and grades of AMS-C-26074 with AMS-2404.
As we blogged about before, the AMS-C-26074 was generated to replace MIL-C-26074 and was taken directly from the source document. After the release of AMS-C-26074 Revision A, the specification was cancelled in favor of the reinstated MIL-C-26074 Revision E. The mil spec was then replaced by MIL-DTL-26074 Revision F which is a controlled distribution document for NAVSEA use only. So the AMS-C-26074 was reinstated as a replacement for the balance of users with the release of Revision B.
Since that time, AMS-2404 has been updated to resolve issues of technical equivalency. So at last the AMS-C-26074 has been put to bed!
Both the current and obsolete AMS documents are available from Document Center Inc., as well as the MIL Specs (with the exception of controlled distribution documents). Order the current editions directly on our website (www.document-center.com) or ask for a quote on the obsolete revisions. That way, we’ll be able to confirm that you recognize obsolete documents are no longer valid and provide you with pricing as well. Or feel free to contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).

ASTM E498-11, titled “Standard Practice for Leaks Using the Mass Spectrometer Leak Detector or Residual Gas Analyzer in the Tracer Probe Mode,” was released this month. It is one of Document Center’s most widely used standards for the non-destructive testing of components.
This practice covers procedures for testing and locating the sources of gas leaking at the rate of 1 × 10−8 Pa m3/s (1 × 10−9 Std cm 3/s) or greater. The test may be conducted on any object to be tested that can be evacuated and to the other side of which helium or other tracer gas may be applied.
Three test methods are described:
1. Test Method A—For the object under test capable of being evacuated, but having no inherent pumping capability.
Test Method A is most frequently used in leak testing components which are structurally capable of being evacuated to pressures of 0.1 Pa (approximately 10−3 torr). Testing of small components can be correlated to calibrated leaks, and the actual leak rate can be measured or acceptance can be based on a maximum allowable leak. For most production needs acceptance is based on acceptance of parts leaking less than an established standard which will ensure safe performance over the projected life of the component. Care must be exercised to ensure that large systems are calibrated with reference leak at a representative place on the test volume. Leak rates are determined by calculating the net gain or loss through a leak in the test part that would cause failure during the expected life of the device.
2. Test Method B—For the object under test with integral pumping capability.
Test Method B is used for testing vacuum systems either as a step in the final test of a new system or as a maintenance practice on equipment used for manufacturing, environmental test or for conditioning parts. As the volume tends to be large, a check of the response time as well as system sensitivity should be made. Volume of the system in liters divided by the speed of the vacuum pump in L/s will give the response time to reach 63 % of the total signal. Response times in excess of a few seconds makes leak detection difficult.
3. Test Method C—For the object under test as in Test Method B, in which the vacuum pumps of the object under test replace those normally used in the leak detector.
Test Method C is to be used only when there is no convenient method of connecting the leak detector to the outlet of the high vacuum pump. If a helium leak detector is used and the high vacuum pump is an ion pump or cryopump, leak testing is best accomplished during the roughing cycle as these pumps leave a relatively high percentage of helium in the high vacuum chamber. This will obscure all but large leaks, and the trace gas will quickly saturate the pumps.
This is the first revision of ASTM E498 since 1995 (that edition was reapproved in 2005). It is available from Document Center Inc., along with all ASTM standards, at our website www.document-center.com. Or call us at 650-591-7600, fax us at 650-591-7617, or send us an email at info@document-center.com.

The new BS EN 55022 2010 Edition has just been released for public distribution. It’s titled “Information technology equipment. Radio disturbance characteristics. Limits and methods of measurement,” and is the official English language edition of the EN 55022:2010. The standard is a modified adoption of the CISPR 22 6th Edition from 2008.
The standard applies to information technology equipment (ITE). Procedures are given for the measurement of the levels of spurious signals generated by the ITE and limits are specified for the frequency range 9 kHz to 400 GHz for both class A and class B equipment. No measurements need be performed at frequencies where no limits are specified. The intention of this publication is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results.
BS EN 55022 applies to 2 EU Directives: EMC Electromagnetic Compatibility (2004/108/EC) and RTTE Radio and telecommunications terminal equipment (1999/5/EC). It replaces the BS EN 55022:2006+A2:2010 Edition, which remains current.
This standard, and all BS documents, are available from Document Center Inc. via our website, www.document-center.com. Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).

BS EN 13480-2:2002 has just been updated with the release of a new edition that includes the A2 Amendment from 2010. Titled “Metallic industrial piping. Materials,” it is the European Standard for metallic industrial piping materials.
BS EN 13480-2 specifies requirements for the selection, inspection, testing and marking of metallic materials for the fabrication of industrial piping. That is, it contains the requirements for materials (including metallic clad materials) for industrial piping and supports covered by EN 13480-1 that are manufactured from metallic materials. The standard is currently limited to steels with sufficient ductility.
Originally released in 2002, the standard was previously modified by AMD 16363, which is a corrigendum (correction). The A2 amendment provides more in-depth changes and requires a repurchase of the document to remain current.
This standard and all BS publications are available from Document Center Inc. via our website at www.document-center.com. Or consider contacting us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).

EIA 364-28F, titled “TP 28F, Vibration Test Procedure for Electrical Connectors and Sockets,” has just been released. It replaces the previous EIA-364-28E dated 8/2006.
EIA 364-28 is one of a series of approximately 110 sub-parts of EIA 364 devoted to various Test Procedures for Connectors and originally released by EIA. Since EIA ceased operations earlier this year (it was the Electronic Industries Alliance when it was founded), this group of documents is actually maintained by the ECA, the Electronic Components Association. And ECA has now consolidated forces with National Electronic Distributors Association (NEDA) to form the Electronic Components Industry Association (ECIA).
The standard test procedure details a method to assess the ability of electrical connector components to withstand specified severities of vibration. The object is to determine the effects of vibration within the predominant or random vibration frequency ranges and magnitudes that may be encountered during the life of the connector.
This EIA Test Procedure and all EIA Standards are available from Document Center Inc. and can be ordered on our website www.document-center.com. Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com). Additionally, many of the previous (obsolete) editions of these standards are available as well.

MIL-HDBK-57 Revision F has just been released. The handbook, titled “Listing of Fastener Manufacturer’s Identification Symbols,” replaces the previous edition MIL-HDBK-57E from 2008. The 252 page handbook is a compilation of the identifying symbols of fastener manufacturers as provided by the manufacturers themselves.
This revision contains the names, addresses, and the symbols of all fastener manufacturers whose identifying symbols were received by November 30, 2006. Additionally, each manufacturer who was listed in a previous revision of this handbook was contacted to confirm the accuracy of the published information. The listing is also annotated to indicate both those manufacturers who have and have not responded to confirm or update appropriate information. Information about manufacturers who have not responded is still maintained in this latest revision.
The document contains both an alphabetic index of manufacturers (Index A) and a listing of manufacturers indexed by their identification symbol (index B). It also contains a registration form and information on how to be included in the listing in the future.
MIL-HDBK-57 defines a manufacturer as a source which substantially makes the supplies, either by hand or machinery, out of raw materials. The term “fasteners” refers to those threaded items included in Federal Supply Class (FSC) numbers 5305 – Screws, 5306 – Bolts, 5307 – Studs, and 5310 – Nuts.
This Handbook and all publicly distributed Military Handbooks, specifications and standards are available from Document Center Inc. through our website, www.document-center.com. You can also contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com). We have a large inventory of obsolete documents as well.
