Safety and Standards--Inseparably Linked [Standards News]

Acoustical Standards News.

American National Standards (ANSI Standards) developed by Accredited Standards Committees S1, S2, S3, S3/SC 1, and S12 in the areas of acoustics, mechanical vibration and shock, bioacoustics, animal bioacoustics, and noise, respectively, are published by the Acoustical Society of America (ASA). In addition to these standards, ASA publishes a catalog of Acoustical American National Standards. To...

Ensuring Reliable Safety Standards

Radiation safety: New international standards

by Abel J. Gonzalez B*y the end of the 1980s, a vast amount of new information had accumulated to prompt a new look at the standards governing protection against exposures to ionizing radiation and the safety of radiation sources. First and foremost, a re-evaluation of the radioepidemiological findings from Hiroshima and Nagasaki suggested that exposure to lowlevel radiation was riskier than pr...

Selection of Food Safety Standards

This paper examines performance versus process standards modeling the variability of industry-level compliance and therefore food safety. Monte Carlo simulations are conducted manipulating four factors: the variances of input use of efficient and inefficient firms, the proportion of inefficient firms in the industry and the policymakers' level of risk aversion. Results suggest that process stan...

Safety-critical systems, formal methods and standards

Standards concerned with the development of safety-critical systems, and the software in such systems in particular, abound today as the software crisis increasingly a ects the world of embedded computer-based systems. The use of formal methods is often advocated as a way of increasing con dence in such systems. This paper examines the industrial use of these techniques, the recommendations con...
