出版:Swiss Standards

专家解读视频
Specifies engineering and survey methods applied to textile machinery with reference to ISO 3744 and ISO 3746 for measuring the sound pressure levels on a measurement surface enveloping the source and for calculating the sound power produced by the source. Specifies the test environment and instrumentation as well as techniques for obtaining the surface sound pressure level. Provides specifications for measuring the noise emitted by textile machines into the ambient air according to uniform methods. Also specifies the measurement of sound pressure levels at the operator position for specified typical conditions, with reference to ISO 6081.
