Product Description

Approved American National StandardThis document provides risk group classification for all ultraviolet lamp systems, and the measurement conditions for different applications, thus superseding the more general risk group classifications used in ANSI/IES RP-27-20 for UV lamp systems. It includes manufacturing and user safety requirements that may be required as a result of an ultraviolet lamp system being assigned to a particular risk group. The assigned risk group of an ultraviolet lamp system also may be used to assist with any needed risk assessments, e.g., for occupational exposure in workplaces.
