Amendments issued for two top Military Microcircuit Specifications, MIL-PRF-19500P and MIL-PRF-38535J

Two of our all-time best selling military specifications for the semiconductor industry have just been modified with amendments:  MIL-PRF-19500, “Semiconductor Devices, General Specification for,” and MIL-PRF-38535, “Integrated Circuits (Microcircuits) Manufacturing, General Specification for.” The new editions are available from Document Center Inc. now.

The new 171-page MIL-PRF-19500P with Amendment 1 establishes the general performance requirements for semiconductor devices. Product assurance is provided by effective screening, conformance inspection, and process controls to mitigate risk. Mission assurance and standardization of parts are the highest priorities. This specification establishes a heritage program of semiconductor devices the military and space community can rely on to be dependable and available.

It contains the performance requirement and verification methods for semiconductor devices. The main body specifies the performance requirements and requires the manufacturer to verify that their devices are capable of meeting those performance requirements.

Appendix A contains definitions of terms used throughout the specification. Appendix B contains abbreviations and symbols. Appendix C contains the Quality Management (QM) Program. Appendix D contains the quality system. Appendix E contains the standard verification system for qualified products. Appendix F has been cancelled. Appendix G contains discrete semiconductor die/ship lot acceptance. Appendix H contains critical interface and materials for semiconductor devices.

The margins of MIL-PRF-19500P with Amendment 1 are marked with asterisks to indicate modifications generated by this amendment. This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contractors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notations.

MIL-PRF-38535J with Amendment 1 establishes the general performance requirements for integrated circuits or microcircuits and the quality and reliability assurance requirements, which are to be met for their acquisition. The intent of this 202-page specification is to allow the device manufacturer the flexibility to implement best commercial practices to the maximum extent possible while still providing product that meets military performance needs.

Appendix A is mandatory for manufacturers of device types supplied in compliance with MIL-STD-883 and forms the basis for QML classes Q and V. Appendix B is intended for space application and is required for V level devices. Appendix C is mandatory for devices requiring radiation hardness assurance (RHA). Appendix D is mandatory for statistical sampling, life test, and qualification procedures used with microcircuits.

Although the document states that marginal notations are not used to identify changes with respect to the previous issue due to the extent of the changes, there are actually a number of sections with marginal notations suggesting that these are the areas when the amendment has generated changes to the text.

New ASTM D471 2012 Edition for Standard Test Method for Rubber Property—Effect of Liquids

ASTM International has just released the new ASTM D471-12, “Standard Test Method for Rubber Property—Effect of Liquids,” and it’s available now from Document Center Inc. in paper, pdf and redline format.  This test method covers the required procedures to evaluate the comparative ability of rubber and rubber-like compositions to withstand the effect of liquids.

This 14-page revision is designed for testing specimens of vulcanized rubber cut from standard sheets, specimens cut from fabric coated with vulcanized rubber, or finished articles of commerce.  It is not applicable to the testing of cellular rubbers, porous compositions, and compressed sheet packing.

Certain rubber articles, for example, seals, gaskets, hoses, diaphragms, and sleeves, may be exposed to oils, greases, fuels, and other fluids during service.  The exposure may be continuous or intermittent and may occur over wide temperature ranges.

Properties of rubber articles deteriorate during exposure to these liquids, affecting the performance of the rubber part, which can result in partial failure.

ASTM D471 attempts to simulate service conditions through controlled accelerated testing, but may not give any direct correlation with actual part performance, since service conditions vary too widely. It yields comparative data on which to base judgment as to expected service quality.

This test method is suitable for specification compliance testing, quality control, referee purposes, and research and development work.  It replaced the old Federal Specification TT-S-735, “Standard Test Fluids, Hydrocarbon,” back in September, 1998.

Document Center Inc. has been selling the ASTM standards under license agreement since the 1980’s.  You can purchase them 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).  We accept PO#’s on a net 30 basis from established customers and VISA, Mastercard and American Express.  Our expert staff is here to assist you with all your standards requirements and questions.

There’s a new ASTM D3350 2012 Revision available for Standard Specification for Polyethylene Plastics Pipe and Fittings Materials

ASTM D3350, “Standard Specification for Polyethylene Plastics Pipe and Fittings Materials,” has just been released as a new 2012 Edition.  This revision replaces the now-obsolete ASTM D3350-10a dated November 2010.   Available from Document Center Inc., the new 7-page specification covers the identification of polyethylene plastic pipe and fitting materials.   It comes in both paper and pdf format, and a redline edition can also be purchased.

Polyethylene plastic materials, being thermoplastic, are reprocessable and recyclable. This specification allows for the use of those polyethylene materials, provided that all specific requirements of this specification are met.

ASTM D3350-12 covers the identification of polyethylene plastic pipe and fittings materials in accordance with a cell classification system. It does not provide specific engineering data for design purposes, to specify manufacturing tolerances, or to determine suitability for use for a specific application.

Cell classification of materials is made according to tests of primary properties like density, melt index, flexural modulus, tensile strength at yield, slow crack growth resistance, and hydrostatic strength classification.  These materials are manufactured by molding and extrusion of polyethylene plastic in the form of powder, granules, or pellets.

Color and ultraviolet stabilizer, thermal stability, brittleness temperature, density, tensile strength at yield, and elongation at break all need to conform to this specification.

There’s a new AMS P 81728 Revision A on Plating, Tin-Lead (Electrodeposited)

SAE has just released the new Revision A for AMS P 81728, “Plating, Tin-Lead (Electrodeposited), ” and it’s available now from Document Center Inc.  This new 13-page revision covers the requirements for electrodeposited tin-lead plating intended for use as a coating for corrosion protection and as a base for soldering.

The document has a long and storied career.  It was originally released in 1969 as MIL-P-81728 with the same title as today.  The document was revised in 1973 and then cancelled and replaced by the AMS-P-81728 in 1998 as part of Mil Spec Reform.  The first AMS publication was a reprint of the original MIL-P-81728 Revision A with the amendment 1 changes included.  Now that Military Specification language has been revised.

The document illustrates how fundamental to many industries the old military standards and specifications were.  Even though they were originally generated to support DoD (Department of Defense) procurement, these publications came to be the standard throughout many U.S. industries, most notably the aerospace sector.  When the military decided that supporting a DoD-based specification bureaucracy was no longer fiscally sound, many of the documents went through a migration into the hands of industry based Standards Developing Organizations.

The continued vitality of a document like the AMS P 81728A is a sign that this migration has been successful in marrying the needs of both the commercial and defense sectors.

U.S. military and SAE standards are available from Document Center Inc. at our website, www.document-center.com.  Or consider contacting us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We can provide you with these documents both in paper and pdf format, as well as monitor and audit your standards collections.  Our reporting services also assist many organizations maintain their collections for continued success with various compliance audits and reviews.

New BS EN 60335-1, 2012 Edition, on Household and similar electrical appliances. Safety. General requirements

BS EN 60335-1:2012, “Household and similar electrical appliances. Safety. General requirements,” has just been released and is now available from Document Center Inc.  The 198 page standard is the UK implementation of EN 60335-1:2012.

BS EN 60335-1 deals with the safety of electrical household appliances – providing their rated voltage is not more than 250 V for single-phase and 480 V for other appliances. These best practice recommendations for electrical safety look at common hazards of household equipment or electrically-operated devices that could cause injury to persons in and around the house.

The standard explains heating, void as well as leakage currents and electric strength at operating temperatures. Other topics include moisture resistance, stability and mechanical hazards, internal wiring and connections.

BS EN 60335-1 looks at the general requirements and conditions to test the domestic safety of electric household appliances. It also defines the classification and marking of electrical equipment, and demonstrates how to ensure protection against live parts.

It is derived from IEC 60335-1:2010, incorporating corrigendum July
2010. It supersedes BS EN 60335-1:2002+A15:2011, which will be
withdrawn on 21 November 2014.

Battery-operated appliances and other d.c. supplied appliances are within the scope of this standard. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. Examples of such appliances are catering equipment, cleaning appliances for commercial use, and appliances for hairdressers.

The principal changes in this edition are as follows:

– updated the text of the standard to align with the most recent editions of the dated normative references;
– modified the functional safety requirements using programmable electronic circuits including software validation requirements;
– updated Clause 29 to cover insulation requirements subjected to high frequency voltages as in switch mode power supply circuits;
– updated Subclause 30.2 to further align the pre-selection option with the end-product test option;
– deleted some notes and converted many other notes to normative text;
– clarified requirements for class III constructions.

National Annex NA (informative) reproduces the original IEC
60335-1:2010 text prior to amendment or deletion by the CENELEC
common modifications.

The Ireland and United Kingdom special national condition in Clause
25.8 of Annex ZA is missing the values in parentheses, which were
introduced in the 2007 corrigendum to BS EN 60335-1:2002. It is
expected that a CENELEC corrigendum will be issued to amend this.

Document Center Inc. sells the BS standards under license agreement on it’s website, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email.  We will be happy to assist you with all your standards requirements and questions.
