New ANSI-Z49.1 2012 Edition just released: Safety In Welding And Cutting And Allied Processes (AWS Z49.1)

There’s a new ANSI Z49.1 2012 Edition, “Safety In Welding And Cutting And Allied Processes,” and it’s available now from Document Center Inc.  Also known as ANSI/AWS Z49.1 and AWS Z49.1, the standard covers all aspects of safety and health in the welding environment, emphasizing oxygen gas and arc welding processes with some coverage given to resistance welding.

Originally developed in 1944, it contains information on protection of personnel and the general area, ventilation, fire prevention and protection, and confined spaces.  A significant section is devoted to precautionary information, showing examples, and an extensive bibliography is included.  The document has proved useful to educators, industrial hygienists, engineers, and other personnel responsible for safety and health in welding over the years.

ANSI Z49.1:2012 has specific provisions for oxyfuel gas and arc welding and cutting, resistance welding, electron beam welding, laser beam cutting and welding, and – new in this edition – brazing and soldering.  The standard is generally applicable to other welding processes such as submerged arc welding and allied processes.

Unions, societies, trade groups, and U.S. military and enforcement agencies – including AWS, Sheet Metal Workers, OSHA, and NIOSH – contributed in the development of this revision of Z49.1.

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.
