Voluntary Standards Cover the Spectrum: from Ophthalmic Optics to Waste Radioactivity


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:

Ophthalmic Optics

Not everyone depends on prescription glasses for perfect 20/20 vision, and plenty of tips abound on how to decide between custom and ready-made frames. One standard exists for those who rely on over-the-counter optics: ANSI Z80.31-2017, Ophthalmics - Ophthalmic Optics - Specifications for Ready-to-Wear Near-Vision Spectacles, which specifies the minimum requirements for complete ready-to-wear near-vision spectacles with positive power available directly to the public without the prescription of a licensed professional – in other words, the drugstore reading glasses that are probably on your nightstand.

The American National Standard (ANS) was developed by the Z80 ANSI-accredited Standards Committee. The Vision Council, a trade association for the optical industry, serves as the secretariat for this committee.

Radioactive Waste

Radioactive materials are used in an increasingly broad spectrum of sectors spanning from manufacturing, hospital research, minerals exploration, and more, so the management of radioactive waste is more essential than ever for public safety. Most facilities that dispose of or utilize waste materials are prohibited from handling waste that contains radioactive materials, which means that special facilities and requirements are needed. It’s also important that these facilities are able to verify generator-supplied information that radioactive or mixed wastes have not been included in shipments of waste materials.

ASTM D5928-18, Standard Practice for Screening of Waste for Radioactivity describes screening for α–, β–, and γ radiation above ambient background levels or user-defined criteria, or both, in liquid, sludge, or solid waste materials.

The standard was developed by ASTM International, an ANSI member and audited designator.
