(1) This clause applies to a sound level meter that is being used to measure and determine the noise level of a motor vehicle accessory, grass-cutting machine, chainsaw or mobile garbage compactor.
(2) A class 1 or 2 sound level meter complying with AS IEC 61672 and associated equipment, including a microphone windshield must be used.
(3) The sound level meter must be set to measure A-weighted noise levels and must have its meter dynamic characteristic set:(a) to "fast", when measuring the noise level of a motor vehicle accessory or chainsaw, or(b) to "slow", when measuring the noise level of a grass-cutting machine or mobile garbage compactor.
(4) The calibration of a sound level meter must be checked, and any necessary adjustments made, immediately before the sound level meter is used to make the noise level measurements required by this Regulation (
"the pre-test check" ) and must be checked again immediately after making those measurements (
"the post-test check" ).
(5) The calibration is to be checked by performing a field calibration, using a reference sound source, when the article whose noise level is being measured is not operating.
(6) If the noise level recorded during the post-test check (after any necessary adjustments have been made) differs by more than 1 dB(A) from the noise level recorded during the pre-test check, then all measurements made in the intervening period must be disregarded.
(7) In this clause:
"AS IEC 61672" means AS IEC 61672--2004, Electroacoustics--Sound level meters , as in force on 1 March 2008.Note : A copy of AS IEC 61672 is available for inspection at the offices of the EPA.
