CEN/TC 169/WG 8 - Photobiology

This European Standard provides a scheme for the classification of artificial non-electrical sources of incoherent optical radiation with regard to their radiation emissions. It helps users of the sources to easily carry out a risk assessment when people can be exposed to radiation from the sources.
This standard applies for sources emitting optical radiation in the wavelength between 180 nm and 3 000 nm.
This standard does not apply for electrically powered sources.
This standard does not apply for machinery, for laser devices and for lamps and lamp systems.
NOTE   A classification for machinery is given in EN 12198-1 [9], a classification for laser devices is given in EN 60825-1 [11] and a classification for lamps and lamp systems is given in EN 62471 [12].

This European Standard specifies procedures for the measurement or estimation and the assessment of personal exposures to ultraviolet radiation emitted by the sun.
NOTE 1   According to CIE 17.4 UV-radiation is defined as an electromagnetic radiation with wavelength between 100 nm and 400 nm. Due to atmospheric absorption only solar UV-radiation in the spectral region between 280 nm and 400 nm reaches the earth's surface in significant amounts.
This European Standard applies to solar UV-exposures when staying outdoors.
This European Standard is applicable to workers and to the general population.
This European Standard does not apply to UV-exposures caused by artificial sources, e.g. UV-lamps, welding arcs.
NOTE 2   Part 1 of this European Standard deals with UV-exposures caused by artificial sources.
NOTE 3   For radiation emissions of products other standards apply, such as CIE S 009 for lamps and lamp systems, EN 60335-2-27 [6] for sunbeds, EN 60335-2-59 [7] for insect killers and EN 12198 [8] for radiation emissions of machinery.
This European Standard does not apply to radiation exposures which concern the retina of the eyes.
NOTE 4   Ultraviolet and visible radiation exposures of the eyes may result in photochemical damage to the retina (this is often called the blue light hazard). The associated action spectrum contains mainly visible radiation and only a very small contribution in the ultraviolet region. The determination and assessment of radiation which may result in a blue light hazard may be done in accordance with part 2 of EN 14255 [20].

This standard specifies the terminology and the quantities that are used in UV-, VIS- and IR-exposure measurements according to parts 1, 2 and 3 of EN 14255.
NOTE   Parts 1 and 2 were published in 2005, while part 3 is under preparation.
This standard can also be applied to the terminology and quantities used in international recommendations from, e.g. ICNIRP, CIE, etc. The purpose of this standard is to unify the definitions of quantities for optical radiation measurements since inconsistencies occur between existing publications from different origins.

This European Standard specifies procedures for the measurement and assessment of personal exposures to visible (VIS) and infrared (IR) radiation emitted by artificial sources, where adverse effects cannot be readily excluded.
NOTE 1   Adverse effects will normally not occur in exposures caused by normal lighting or room heating.
This European Standard applies to VIS- and IR- exposures in indoor and outdoor workplaces. It does not apply to VIS- and IR-exposures in leisure time.
This European Standard does not apply to VIS- and IR- exposures caused by the sun.
NOTE 2   Part 3 of this standard will deal with UV-exposures caused by the sun.
This European Standard does not specify VIS- and IR-exposure limit values. It supports the application of limit values set by national regulations or international recommendations.
This European Standard applies to VIS- and IR- exposures by artificial incoherent sources, which emit spectral lines as well as continuous spectra. This European Standard does not apply to coherent radiation sources.
NOTE 3   Coherent optical radiation sources are covered by standards for lasers, like EN 60825-1 etc.
This European Standard applies to visible (VIS) and infrared (IR) radiation exposures in the wavelength band 380 nm to 3 µm. It also applies to radiation exposures that may present a blue-light hazard in the wavelength band 300 nm to 700 nm.
This European Standard does not apply to other effects of which the action spectra lie solely within the
UV-region 180 nm to 400 nm.
NOTE 4   Part 1 of EN 14255 addresses these effects.
This European Standard does not apply to radiation emissions of products.
NOTE 5   For radiation emissions of products other standards apply, such as EN 12198 for radiation emissions of machinery, EN 60335-2-27 for household appliances for skin exposures to ultraviolet and infrared radiation and CIE S009 for the safety of lamps and lamp systems.
This European Standard does not apply to heat stress, i.e. long term heat

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 1   Adverse 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.
