Voluntary Standards Cover the Spectrum: from Hi-Tech Elevators to Aerospace Welding

New York, Jan 17, 2007

In an effort to communicate the vital role that standards play in daily life, ANSI Online will publish, on an ongoing basis, a series of snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow:

Hi-Tech Elevators
It’s useless to deny. We’ve all tried it. Arriving last minute for an appointment or just anxious to get home, earnestly punching the call button time and again in the hopes of making the elevator move more quickly. The latest in elevator technology may finally hold the key to elevator gridlock, and do what stubborn button pushing never could.

New microprocessor-based elevator technologies use algorithms to evaluate traffic trends and determine which cars—and how many of them—are needed to optimize passenger traffic and speed riders to their designated floors. A new standard from the American Society of Mechanical Engineers (ASME) provides a uniform approach for evaluating the safety of elevators and escalators that make use of new and alternative technologies.

ANSI/ASME A17.7/CSA B44.7-2006, Performance Based Safety Code for Elevators and Escalators, was developed by the ASME A17 New Technology Committee. The group was formed in 2003 when ASME’s A17 committee joined forces with Canadian Standards Association’s (CSA) B44 committee to develop a performance-based safety code that would allow for the safe introduction of alternative technology elevators in the United States and Canada.

Aerospace Welding
Virtually all industries rely heavily on welding processes at some stage of the manufacturing process or in the repair and maintenance of equipment. From computer circuit boards to medical equipment to high-strength automotive steels, industry looks to welding for the reliable joining of materials.

A new American National Standard from the American Welding Society (AWS) covers resistance welding methods for metals used in the manufacture of aviation and aerospace equipment. AWS D17.2/ D17.2M:2007, Specification for Resistance Welding for Aerospace Applications, also details criteria for machine and procedure qualification and the inspection of aerospace hardware.

The standard was developed by the AWS D17 committee on welding in the aircraft and aerospace industry, a group comprised of experts from major aircraft, defense, and space manufacturers. The document is intended to replace the federal standards in this area, MIL-W-6858D and AMS-W-6858A.

This "standards snapshot" was made possible by the steady stream of press information disseminated by standards developing organizations to keep the ANSI Federation abreast of their achievements. As the Institute receives news of published voluntary standards and voluntary standards initiatives with broad appeal and impact, similar articles will be posted to the ANSI Online News page.
