Voluntary Standards Cover the Spectrum: from Horticultural Lighting Systems to Cylindrical Wormgearing


11/11/2019

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:

Lighting Systems for Horticultural Environments
Indoor farming is gaining popularity as scientists raise increasing concerns about the ability of conventional agriculture to meet the food requirements for the world’s growing population. Specially-designed lighting systems that support optimal plant growth are critical in these indoor, controlled agriculture environments. A new American National Standard (ANS) developed by UL, UL 8800 Ed. 1-2019, Standard for Horticultural Lighting Equipment and Systems, guides this technology when installed in accordance with the U.S. National Electrical Code, ANSI/NFPA 70, and the Canadian Electrical Code, Part 1. It addresses photobiological safety concerns with these lighting systems, and guides cautionary or warning markings required on products and accompanying instructions.

An ANSI audited designator and organizational member, UL is an independent product safety certification organization that tests products and writes standards to promote safe living and working environments for products, components, materials, and systems.

Cylindrical Wormgearing Design
When a machine or mechanism requires a gear that can offer a delicate speed adjustment using a large speed reduction, a worm gear is often employed. Used for gear boxes, fishing pole reels, instrument string tuning pegs, and many other applications, worm gears are compact, self-locking, and quiet. A new ANS developed by the American Gear Manufacturers Association (AGMA) provides guidelines for the design of fine and coarse pitch cylindrical wormgearing operating at right angles, primarily made as gear sets to be incorporated into other machines and mechanisms. ANSI/AGMA 6022-D19, Design Manual for Cylindrical Wormgearing, also offers many design procedures that can be incorporated in enclosed drives.

AGMA, an ANSI member and accredited standards developer, is a membership organization comprised of companies, consultants, and other stakeholders with a direct interest in the design, manufacture, and application of gears, couplings, and related power transmission components and equipment.
