Product Description
This document covers the classification, labeling and informational requirements for lamps that emit optical radiation in the wavelength range from 200 nm to 3,000 nm, with exception for LEDs used in optical fiber communication systems and for lasers. Lamps included are incandescent filament lamps including tungsten halogen types and incandescent heating sources, low pressure discharge lamps, high intensity discharge (HID) lamps, short arc lamps, carbon arcs, electroluminescent lamps, LEDs, organic LEDs (OLEDs), and laser-driven broadband sources. Specific recommendations are included to provide consistency and to reduce test design time and effort. Further, this document is to be used by the radiometrist for guidance regarding special problems related to photobiological hazard measurements. This Recommended Practice combines and updates the material from the previous ANSI/IES RP-27 series:
- ANSI/IES RP-27.1-15, Recommended Practice for Photobiological Safety for Lamps and Lamp Systems – General Requirements
- ANSI/IES RP-27.2-00(R17), Recommended Practice for Photobiological Safety for Lamps and Lamp Systems – Measurement Techniques
- ANSI/IES RP-27.3-17, Recommended Practice for Photobiological Safety for Lamps and Lamp Systems – Risk Group Classification and Labeling
