Voluntary Standards Cover the Spectrum: from Air Recirculation to Ink Mills

New York, Feb 15, 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:

Air Recirculation
In the workplace and at home, air quality is essential to the health and comfort of building occupants. In commercial buildings, air recirculation is commonly used for the purposes of thermal conditioning. If not properly maintained however, recirculation of air can pose unseen dangers, allowing air contaminants to build to concentrations that can set off respiratory ailments and other health problems.

Industrial processes in particular necessitate special ventilation provisions to prevent the release of contaminated air. To assist those responsible for designing and maintaining a safe air recirculation system in such settings, ANSI member the American Industrial Hygiene Association recently published an American National Standard guiding the recirculation of air in industrial processes.

ANSI/AIHA Z9.7-2007, Recirculation of Air, establishes minimum criteria for the design and operation of recirculating exhaust systems used for contaminant control in the workplace. Potential safety problems are addressed, as are the materials and processes used to identify possible contaminants generated from industrial processes. The standard was developed by ANSI-accredited standard committee (ASC) Z9, which is responsible for the development of health and safety standards for ventilation systems in industrial, manufacturing or construction operations. AIHA serves as the secretariat for ASC Z9.

Ink Mills
From bookbinding machines to inkjet media to computer-to-paper desktop devices, the printing, publishing and converting industries help to drive essential business functions in numerous industry sectors every day. ANSI member NPES (the Association for Suppliers of Printing, Publishing and Converting Technologies) leads the development of voluntary standards that impact printing, publishing and converting processes from design to distribution.

NPES recently revised its American National Standard for three roll ink mills used in the manufacture of printing inks. ANSI/NAPIM 177.1-2007, Safety standard - Three roll printing ink mills, details safety requirements intended to reduce the risk of injury to personnel during the operation of these machines. The document provides guidance to equipment designers, operators and owners with respect to safety controls, operating procedures and equipment design. The revision of the standard was led by the ANSI-accredited B65 Committee, for which NPES serves as secretariat.

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.
