scope:

Recommendations in this document apply only to lamps and lamp systems designed primarily to emit ultraviolet (UV) radiant energy for consumer, industrial, scientific, and medical applications. The scope is limited to lamps and lamp systems where more than half of the optical radiation emitted between 180 nm and 3,000 nm is in the spectral region 180 nm to 400 nm. If more than half of the optical radiation emitted between 180 nm to 3,000 nm is outside of the spectral region 180 nm to 400 nm, then the base standard, ANSI/IES RP-27-20, applies.

ANSI/IES RP-27.1-22 does not apply to general lighting sources (GLS) or laser systems.
