Table 1 Risk group classification
Limitations
Classification is determined by UV light irradiance values at 20 cm distance – relates to the
UV light emission of the source rather than characterising the exposure of a person – may
not be appropriate for many applications.
Applies to normal operation only – may be not applicable to maintenance, service or
abnormal operation (e.g. with broken filter glass). Relates to a single product – doesn’t
account for accumulative exposure from multiple sources.
Exempt group regarding the un-weighted UV-A limit is based on the ACGIH integration
duration of 1,000 seconds – exposure to such lamps at a distance of 20 cm for longer than 16
minutes could lead to exceeding the ICNIRP ELV, where the integration duration is 8 hours.
