Optics and photonics. Environmental test methods - High internal pressure, low internal pressure, immersion Ingestion-build-202139 The following cases are not1 Scope This part of ISO 9022 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
