Bibliography

This document specifies procedures for the measurement and assessment of personal exposures to ultraviolet (UV) radiation emitted by artificial sources, where adverse effects can not readily be excluded.NOTE 1Adverse effects will usually not occur in exposures caused by commonly used artificial lighting. However, exposures to very strong light sources or light sources with extended spectra may cause a health risk nevertheless.This document applies to UV-exposures in indoor and outdoor workplaces. It does not apply to UV-exposures in leisure time. This document does not apply to UV-exposure caused by the sun.NOTE 2Part 3 of this standard will deal with UV-exposure caused by the sun.This document does not specify UV-exposure limit values. It supports the application of limit values set by national regulations or international recommendations. This document applies to UV-exposures by artificial incoherent sources, which emit spectral lines as well as continuous spectra. This document does not apply to coherent radiation sources.NOTE 3Coherent optical radiation sources are covered by standards for lasers, like EN 60825-1 etc..This document applies to UV-exposures in the wavelength band 180 nm to 400 nm. This document does not apply to radiation exposures which concern the retina.NOTE 4Part 2 of this standard will address these effects.This document does not apply to radiation emissions of products. NOTE 5For radiation emissions of products other standards apply, such as: EN 60335-2-27 (IEC 60335-2-27) for sunbeds, EN 60335-2-59 (IEC 60335-2-59) for insect killers and EN 12198 for radiation emissions of machinery.
