标准摘要
[中文适用范围]： ISO 9022的这一部分规定了光学仪器的环境测试方法，包括其他领域的附加组件（例如机械、化学和电子设备），在同等条件下，测试其抵抗盐雾影响的能力。 暴露于盐雾中主要导致金属腐蚀。 运动部件的堵塞或粘连也可能会产生影响。 测试的目的是尽早评估仪器，特别是仪器的表面和保护涂层抵抗盐气氛影响的能力。 [外文原描述]： ISO 9022-4:2014 specifies the methods relating to the environmental tests of optical instruments including additional assemblies from other fields (e.g. mechanical, chemical, and electronic devices), under equivalent conditions, for their ability to resist the influence of salt mist. Exposure to salt mist mainly results in the corrosion of metals. Effects might also occur by way of clogging or binding of moving parts. The purpose of the testing is to assess, as early as possible, the ability of the instrument, and particularly of the surfaces and protective coatings of the instrument, to resist the effects of a salt atmosphere. Normally, representative samples or complete small units are used for testing. Complete large instruments or assemblies are only tested as specified in this part of ISO 9022 in exceptional cases.
