Voluntary Standards Cover the Spectrum: from Drinking Water System Components to Electric Meters


In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes 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:

Drinking Water System Components-Health Effects

Clean, safe drinking water is a critical requirement for healthy societies. While H2O is available from multiple sources, including public and private systems, it is essential to know where water comes from and whether it is safe to drink to avoid unhealthy outcomes. An American National Standard (ANS) developed by NSF International, NSF/ANSI 61-2015, Drinking Water System Components - Health Effects, sets health effects criteria for many water system components including: protective barrier materials (cements, paints, coatings), joining and sealing materials (gaskets, adhesives, lubricants), mechanical devices (water meters, valves, filters), pipes and related products (pipe, hose, fittings), plumbing devices (faucets, drinking fountains), process media (filter media, ion exchange resins), and non-metallic potable water materials.

An ANSI member and accredited standards developer, NSF International writes public health standards and protocols and tests, and certifies products for the water, food, and consumer goods industries.

Electric Metering

Standard electric meters are used to measure the amount of electricity used in businesses, utilities, and private residences, and can provide crucial information about energy consumption and conservation. The newly revised ANS ANSI C12.1-2014,Electric Meters - Code for Electricity Metering,establishes acceptable performance criteria for new types of ac watt hour meters, demand meters, demand registers, pulse devices, and auxiliary devices. It describes acceptable in-service performance levels for meters and devices used in revenue metering. The standard also includes information on related subjects, such as recommended measurement standards, installation requirements, test methods, and test schedules. The ANS was designed as a reference for those concerned with the art of electricity metering, such as utilities, manufacturers, and regulatory bodies.

The ANS was developed by the National Electrical Manufacturers Association (NEMA), an ANSI member and accredited standards developer, by the accredited standards committee for Electricity Metering, C12.

NEMA represents nearly 400 electrical, medical imaging, and radiation therapy manufacturers at the forefront of electrical safety, reliability, resilience, efficiency, and energy security. Its combined industries account for more than 400,000 American jobs and more than 7,000 facilities across the U.S.
