1.1This test method calculates the overall A-weighted sound power level emitted by small portable upright, canister, combination vacuum cleaners, backpack vacuum cleaners, hard-floor machines, and central vacuum cleaner motorized nozzles intended for operation in domestic and commercial applications.
1.1.1To determine the Sound Power Level of a central vacuum at the power unit location refer to Test Method F2544.
1.2A-weighted sound pressure measurements are performed on a stationary vacuum cleaner in a semi-reverberant room. This test method determines sound power by a comparison method for small noise sources, that is, comparison to a broadband reference sound source.
1.3This test method describes a procedure for determining the approximate A-weighted sound power level of small noise sources. This test method uses a non-special semi-reverberant room.
1.4Results are expressed as A-weighted sound power level in decibels (referenced to one picowatt).
1.5The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.
1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
