Voluntary Standards Cover the Spectrum: from Bridge Welding to Nuclear Facilities

New York, Aug 19, 2008

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:

Bridge Welding
More than 600,000 U.S. bridges link a network of local, state, and interstate roadways used for recreation, commerce, and evacuation in times of crisis. A recently updated American National Standard from ANSI organizational member and accredited standards developer, the American Welding Society (AWS), will ensure that these integral components of the U.S. transportation infrastructure are built and repaired accurately.

AASHTO/AWS D1.5M/D1.5: 2008, Bridge Welding Code, published in partnership with the American Association of State Highway and Transportation Officials (AASHTO), covers best practices and general provisions of routine bridge welding requirements for AASHTO welded bridges made from carbon and low-alloy constructional steels. The new standard revises a 2002 edition and provides specifications for inspection, qualification, structural details, stud welding, welded joint details, and workmanship. Other revisions include additions and updates to usage, handling, and storage requirements for consumables, performance test specifications, filler metal variables, inspection personnel qualifications, and high-performance steel grades.

AASHTO/AWS D1.5M/D1.5: 2008 meets industry-wide demand for a single document that not only provides cost-effective bridge fabrication approaches, but also addresses structural integrity and public safety concerns.

AWS is a professional membership organization that works to advance the science, technology and application of welding and related disciplines including automatic, semi-automatic and manual welding, brazing, soldering, ceramics, lamination, robotics, and welding safety and health.

Nuclear Facilities
According to the U.S. Nuclear Regulatory Commission, 104 nuclear power plants currently generate 20% of the nation’s electricity. The social, political, and economic factors involved in guaranteeing safe, reliable, and efficient delivery of this electricity requires nuclear facilities to be carefully managed throughout their average 40-year life cycle. To aid in this effort from design through decommissioning, ASME recently published an updated American National Standard, ANSI/ASME NQA-1-2008, Quality Assurance Requirements for Nuclear Facility Applications.

This standard provides guidelines for the management and processing of radioactive materials; focuses on the achievement of results; emphasizes the role of the individual and line management in the achievement of quality; and fosters the application of these requirements in a manner consistent with the relative importance of the item or activity.

First published in 1979, the 2008 edition of ANSI/ASME NQA-1 reflects current industry experience and current understanding of the quality assurance requirements necessary to achieve safe, reliable, and efficient utilization of nuclear energy.

ASME, a not-for-profit, professional membership organization, is an ANSI organizational member and accredited standards developer that promotes the art, science and practice of mechanical and multidisciplinary engineering and allied sciences through the development of codes and standards that enhance public safety.
