Voluntary Standards Cover the Spectrum: From Water Distribution Systems to Manufactured Housing Installation

New York, Feb 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:

Safer Drinking Water
Thirsty? There is no better way to quench thirst than a tall drink of cool clean water. Did you ever take a moment to think about the journey that water makes from its original source to your kitchen sink, the office cooler, or to that glass of ice water that is usually placed in front of you at a restaurant?

The NSF Water Distribution Program is responsible for the certification of both drinking water treatment chemicals and drinking water system components to ensure that these products do not contribute contaminants to drinking water that could cause adverse health effects. An ANSI member and accredited standards developer, NSF International recently revised ANSI/NSF 61-2005 (i51), Drinking Water System Components – Health Effects, the nationally recognized health effects standard for all devices, components and materials that contact drinking water.

ANSI/NSF 61 also covers indirect additives, products and materials, including process media, protective materials, joining and sealing materials, pipes and related products, mechanical devices and mechanical plumbing devises including faucets. Certification assures that finished products meet all requirements. For additional information relating to this standard, please visit:

Manufactured Housing Installation
Not so long ago the phrase “model housing” brought to mind an image of rows of small, cheap, generic houses. Today, there is an almost overwhelming array of designs to choose from that allows homeowners to personalize their home so that it suits both style and needs. There are three basic methods to build homes: site-built, modular (or factory-built) and manufactured. Site-built refers to homes fabricated primarily on the job site and modular, or factory-built, refers to homes built in a factory in sections. Manufactured housing refers to a house built off-site in a factory or construction yard on a permanent chassis with a HUD (U.S. Department of Housing and Urban Development) label. These homes are built to the HUD code under the Federal Manufactured Housing Construction and Safety Standards established in 1976.

Equally important as the construction of the manufactured home are the techniques and materials used (i.e., structural support, etc.) in its installation. The National Fire Protection Association (NFPA), an ANSI member and accredited standards developer, has introduced a new standard for Model Manufactured Home Installation, NFPA 225, that provides provisions for the preparation of sites intended for manufactured homes, foundations on which the manufactured homes are installed, procedures for on-site installation and erection, as well as the management of appliances and utility connections. Updated criteria in this standard cover the anchoring of the home and protection against seismic events, floods and wind. These guidelines will help ensure that manufactured homes are efficiently, effectively, safely and adequately installed. For additional information, please visit:

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.
