Voluntary Standards Cover the Spectrum: From Household Electric Room Air Cleaners to Laser Safety Measurements

New York, Dec 22, 2005

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:

Household Electric Room Air Cleaners
Dust, pollen, pet dander, and other airborne particles in the home are an assault on someone suffering from certain allergies. Household room air cleaners provide one line of defense, and their performance is guided by a standard from ANSI member and accredited standards developer the Association of Home Appliance Manufacturers (AHAM).

The American National Standard for the Performance of Portable Household Electric Room Air Cleaners, ANSI/AHAM-AC-1-2006, is a performance test method to measure room air cleaner performance of removal of airborne particulates. The standard was recently updated by AHAM following an independent peer review by a panel of indoor air quality experts and includes the addition of a suggested room size calculation. The accredited standard also includes the addition of optional operating power and standby power tests and several clarifying edits.

The AC-1 test method serves as the basis for AHAM's Clean Air Delivery Rate (CADR) Certification Program and is also used by Consumer Reports in its air cleaner performance testing. More information on the Clean Air Delivery Rate Certification Program is available at

Laser Safety Measurements
The optical dexterity and utility of lasers allows for their wide application across industries and technologies. ANSI member and accredited standards developer the Laser Institute of America (LIA) is the professional society dedicated to fostering lasers, laser applications and laser safety worldwide.

LIA recently published ANSI Z136.4 (2005), Recommended Practice for Laser Safety Measurements for Hazard Evaluation. This American National Standard recommended practice provides guidance for optical measurements associated with laser safety requirements. It is intended to assist users who are entrusted with the responsibility of conducting laser hazard evaluations to ensure that appropriate control measures are implemented. The recommended practice document contains clearly written definitions, examples, and other practical information for laser safety officers, technicians, medical practitioners, educators, and other professionals. The comprehensive guide represents years of effort by laser safety experts representing the Department of Defense, Department of Energy, the Food and Drug Administration, the National Institute of Standards and Technology, industrial laser manufacturers, laser operators, academic contributors and others.

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.
