ASTM F2544: Standard Test Method for Determining A-Weighted Sound Power Level of Central Vacuum Power Units
Abstract: This test method calculates the overall A-weighted sound power level emitted by central vacuum power units, intended for operation in domestic applications. This standard applies to the power unit only at the power unit location. To test the sound power level of a central vacuum at the user’s location, refer to Test Method F 1334.
