BS 7580-2:1997

This standard BS 7580-2:1997 Specification for the verification of sound level meters is classified in these ICS categories:

• 17.140.50 Electroacoustics

This Part of BS 7580 specifies a procedure for a limited periodic verification test of Type 2 sound level meters, and includes test methods and the information to be shown on the certificate. This procedure is intended to verify the correct operation of a limited range of features of the sound level meter. This Part of BS 7580 specifies requirements for both the calibration laboratory and the user.

This Part of BS 7580 is applicable to Type 2 sound level meters originally manufactured in accordance with BS EN 60651 and BS EN 60804, and is based largely on the tests in Part 1. It is applicable to models of sound level meter that have successfully undergone a full pattern evaluation test to BS EN 60651: 1994 and/or BS EN 60804 : 1994 as appropriate, or to individual sound level meters that have successfully undergone a full verification in accordance with BS 7580 : Part 1. The sound level meter is supplied for test together with a sound calibrator.

Specifies a shortened verification test procedure for type 2 sound level meters which are used for general field applications.
