Voluntary Standards Cover the Spectrum: From Vending Machines to Plumbing


New York, Oct 23, 2003

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 some 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:

Vending Machines

From cheese puffs to gourmet chocolate chip cookies, vending machines are the convenient answer to a snack-attack. No longer limited to chips and soda, these mini food marts are also evolving to serve hot and cold food items, and in some cases personal care products. To operate safely and efficiently, vending machines require continual maintenance and adhere to specific standards.

ANSI/UL 751-2003, Standard for Vending Machines, covers all self-contained, coin-operated vending machines that vend non-refrigerated products to be employed in accordance with the American National Standard Electrical Code, NFPA 70. Vending machines as covered by this standard are intended for indoor use only. Refrigerated vending machines are covered by ANSI/UL 541-2001, Vending Machines, Refrigerated. Under this standard, refrigerated vending machines are intended for connection to alternating-current circuits rated 600 volts or less and which incorporate refrigeration systems of the air-cooled or water-cooled type employing hermetic refrigerant motor-compressors. This standard does not cover machines that have a principal function other than storage and dispensing of refrigerated products.

Underwriters Laboratories Inc. (UL) is an independent, not-for-profit product safety testing and certification organization, testing products for public safety for more than a century.

Plumbing

The Standard Plumbing Code published in 1932 was the first of the International Association of Plumbing and Mechanical Officials’ (IAPMO) codes and served as a major step toward uniformity. Also published at that time were the Standard Gas Code and the Standard Water Pipe Code. These three codes were later compiled into one document known as the Uniform Plumbing Code (UPC). The 2003 edition of the UPC has been developed utilizing the ANSI-accredited organization consensus method and is a part of the first fully integrated ANSI-accredited consensus based code set known as the Comprehensive Consensus Codes™ (C3). The UPC and Uniform Mechanical Code are the most widely adopted plumbing and mechanical codes in the United States.

ANSI/IAPMO UPC 1-2003, Uniform Plumbing Code, provides minimum standards and requirements to safeguard life or limb, health, property and public welfare by regulating and controlling the design, construction, installation, quality of materials, location, operation and maintenance or use of plumbing systems. The provisions of this code apply to the erection, installation, alteration, repair, relocation, replacement, addition to, use or maintenance of plumbing systems.


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.
