标准摘要
[中文适用范围]： 本ISO 9022部分规定了用于检查光学设备（包括其来自其他领域的可能附加组件，如机械、化学和电子装置）在相同条件下抵抗含二氧化硫（SO2）或含硫化氢（H2S）潮湿大气的能力的程序。测试的目的是确定光学设备的光学、气候、机械、化学和电气特性在受到二氧化硫或硫化氢影响时的受损程度。本ISO 9022部分不适用于使用代表性样品对材料和表面涂层在高浓度二氧化硫下的耐腐蚀性进行测试。此类测试应适用相应的材料测试标准。 [外文原描述]： ISO 9022-20:2014 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 sulfur dioxide (SO2) or hydrogen sulfide (H2S) in a humid atmosphere. The purpose of the testing is to investigate to what extent optical, climatic, mechanical, chemical, and electrical performance characteristics of the specimen are affected by sulfur dioxide or hydrogen sulfide. ISO 9022-20:2014 is not applicable to the testing of material and surface coatings for their corrosion resistance using high concentrations of sulfur dioxide, for which representative samples are generally used as specimens. The appropriate material standards apply to tests of this type.
