ISO 9022-8:2015规定了与光学仪器（包括其他领域（如机械、化学和电子设备）在同等条件下的环境试验相关的方法，以确保其能够抵抗高压、低压或浸没的影响。 测试的目的是调查试样的光学、气候、机械、化学和电气性能特征在多大程度上受到高压、低压或浸入的影响。

ISO 9022-8:2015 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 high pressure, low pressure, or immersion. The purpose of testing is to investigate to what extent the optical, climatic, mechanical, chemical, and electrical performance characteristics of the specimen are affected by high pressure, low pressure, or immersion.
