英文名称：Pneumatic fluid power — Test methods for measuring acoustic emission pressure levels of exhaust silencers

发布日期：2019-10

标准范围

This document specifies two methods of measuring the level of acoustic pressure at the outlet of an 
exhaust silencer:
— the first method, called "steady-state mode”, is intended to evaluate the noise level under steady 
state flow, i.e. constant upstream pressure (steady-state test according to ISO 6358-1); and
— the second method, called “discharge”, is intended to measure the noise level during the decrease of 
the pneumatic pressure (discharge test according to ISO 6358-2).
This document is applicable to pneumatic exhaust silencers and devices designed to reduce the sound 
produced by discharges of compressed air, entering in the scope of application of ISO 6358-1 and 
ISO 6358-2.
