ISO 9022-17:2015规定了与光学仪器的环境试验有关的方法，包括在同等条件下对其他领域（如机械、化学和电子设备）的附加组件进行环境试验的方法，以确保其能够抵抗组合污染和太阳辐射的影响。ISO 9022-17:2015中使用的“污染”是指光学仪器与腐蚀性化学物质（以下简称测试剂）的接触。 但是，除非有特殊原因（参考ISO 9022-17:2015），否则不得根据ISO 9022-17:2015对完整的仪器或组件进行测试- 12). 通常，代表性基底被用作试样。 ISO 9022-17:2015中所述的测试旨在为在使用寿命期间可能受到复合污染和太阳辐射的仪器选择材料和组件，而不是用于常规生产控制。 测试的目的是调查仪器，尤其是仪器表面、涂层或合成材料在短时间内暴露于测试试剂和太阳辐射的耐受性。

ISO 9022-17:2015 specifies the methods relating to the environmental tests of optical instruments and including additional assemblies from other fields (e.g. mechanical, chemical, and electronic devices) under equivalent conditions, for their ability to resist the influence of combined contamination and solar radiation. "Contamination", as used in ISO 9022-17:2015, means the contact of optical instruments with corrosive chemical substances (hereafter called test agents). Complete instruments or assemblies are, however, not be tested to ISO 9022-17:2015 except for special reasons (refer to ISO 9022-12). As a rule, representative substrates are used as specimens. The tests described in ISO 9022-17:2015 are designed for the selection of materials and components for instruments likely to be subjected to combined contamination and solar radiation during service life, rather than for regular production control. The purpose of testing is to investigate the resistance of an instrument, and in particular, of instrument surfaces, coatings, or synthetic materials, to a short-time exposure to the test agents combined with solar radiation.
