Voluntary Standards Cover the Spectrum: from Welding of Zirconium to Fire Safety Symbols


New York, Jun 20, 2012

In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) 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:

Welding of Zirconium
Sometimes erroneously called cubic zirconium, the diamond substitute cubic zirconia is only one application of the base element zirconium, a corrosion-resistant metal similar to titanium and stainless steel. Zirconium or zirconium alloys are used in chemical plants, nuclear reactors, electronic devices, joint implants, photography, pyrotechnics, vacuum tubes, satellites, ceramic, bricks and cement, inks and paints, and antiperspirant.

To aid welders in fusing zirconium and zirconium alloys to other metals, the American Welding Society (AWS), an ANSI organizational member and accredited standards developer, has published AWS G2.5/G2.5M:2012, Guide for the Fusion Welding of Zirconium and Zirconium Alloys. The new American National Standard (ANS) explains processes, equipment, materials, workshop practices, joint preparation, welding techniques, tests, and the repair of defects used in zirconium fabrication. The guide provides detailed and technical information on best practices, enabling first time users of zirconium, as well as established fabricators, to join zirconium parts into high quality components.

AWS is a non-profit membership organization that seeks to advance the science, technology, and application of welding and allied joining and cutting processes including brazing, soldering, thermal spraying, ceramics, lamination, robotics, and health and safety. From factory floor to high-rise construction, and from military weaponry to home products, AWS supports welding education and technology development.

Fire Safety Symbols
Hazard symbols are designed to warn about dangerous materials, locations, or emergency situations. Easily recognizable, the symbols are essential for fire service and operations, architectural and engineering drawings, insurance diagrams, pre-incident planning sketches, and the general public. To help ensure safety in the event of a fire, the National Fire Protection Association (NFPA) recently released revised ANS NFPA 170: 2012, Standard for Fire Safety Symbols.

The new ANS provides references and symbols for visually alerting building occupants during fire and related life safety emergencies including fire protection symbols for the architectural, engineering, and allied design fields; diagrams employed in fire risk and loss analysis; alerting fire fighters during fire and related emergencies; water supply, extinguishing, and sprinkler system drawings; electronic fire and smoke detection and notification system drawings; pre-incident planning sketches; emergency management mapping, evacuation diagrams, and plans; and related insurance diagrams for each category of symbols.

NFPA, an ANSI audited designator and organizational member, is a non-profit organization with an international scope that provides and advocates consensus codes and standards, research, training, and education to reduce the worldwide burden of fire and other hazards.
