GB/T 21271-2026 Vacuum technology—Noise measurement for vacuum pumps
Abstract
This document describes the measurement methods for the emission noise of vacuum pumps and their components, which mainly include the following two items:
—— Sound power level under load conditions;
—— Sound pressure level emitted at the working position under load conditions.
This document specifies the acoustic environment, measurement instruments, installation of vacuum pumps and their components, load and operating conditions, test reports, and requirements for marking and verifying noise emission values during the measurement of noise from vacuum pumps and their components.
This document is applicable to the noise measurement of mechanical vacuum pumps and their components (hereinafter referred to as pumps). This document does not describe the analysis of the harmonic band, but it is also applicable when it is related to it.
