GB/T 2423.47-1997 in English

《GB/T 2423.47-1997电工电子产品环境试验 第2部分:试验方法 试验Fg:声振》由TC8（全国电工电子产品环境条件与环境试验标准化技术委员会）归口，TC8SC1（全国电工电子产品环境条件与环境试验标准化技术委员会机械环境试验分会）执行，主管部门为中国电器工业协会。
本标准的目的是提供一种用来确定样品承受得起规定噪声环境引起振动或由其形成倾向的声导试验的试验程序和导则。

Scope

The purpose of this standard is to provide a test procedure and guidance for the acoustic conduction test used to determine that the sample can withstand the vibration caused by the specified noise environment or the tendency caused by it, and there is no requirement for the sound test of the sound pressure level environment below 120dB . Under the specified acoustic test conditions, determine the mechanical weakness and degradation of the test specimens and evaluate their acceptability together with other provisions. In some cases, this test method is also used as a method to determine the mechanical strength or fatigue strength of the test specimen. This standard describes the acoustic vibration test and the process of measuring the sound pressure level in a noisy environment and takes into account the need to measure the vibration response of a specific point of the test sample. Guidance is also given for the selection of the noise environment, frequency spectrum, sound pressure level and duration of exposure.
