Scope

This standard stipulates the measurement method and labeling of the emission noise of vacuum pumps, specifies the installation, load and working conditions during measurement, and specifies the following two measurement and expression methods of emission noise: - specifies the sound power level under load conditions; - Specifies the sound pressure level emitted at the work position under load conditions. This standard applies to the noise measurement of mechanical vacuum pumps (hereinafter referred to as pumps).
