BS EN 61252:1997+A2:2017 is applicable to instruments for measurement of A-frequency-weighted sound exposure resulting from steady, intermittent, fluctuating, irregular, or impulsive sounds. Instruments complying with the specifications of this International Standard are intended to be worn on a person to measure sound exposure. Measurements of sound exposure in the workplace may be useful for determinations of occupational noise exposure, in accordance with ISO 1999 and ISO 9612.Cross References:EN 60651:1994EN 61000-4-3:1996EN 55022:1998IEC 60801-3:1984EN 55022:1998/Corrigendum 1:1999IEC 60801-2:1984EN 60804:1994IEC 61000-6-1:1997IEC 60942:1988IEC 60651:1979HD 481.3 S1:1987IEC 60050-801:1984EN 61000-4-2:1995HD 556 S1:1991IEC 60804:1985IEC 61000-4-20:2010EN 61000-4-20 (IEC 61000-4-20:2010)ASIEC 61000-4-3:1995 Cons Ed 1-2IEC 61000-6-2:1999ISO 1683IEC 61000-6-3:1996CISPR 22:1997EN 61000-6-2 (IEC 61000-6-2:1999 Adop)IEC 61000-4-2:1995ISO 1999:1990EN 60801-2:1993ISO 266ISO 9612:1997Incorporates the following:Amendment, April 2018; Amendment, September 2001
