DIN ISO 9022-8:2015-08

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 internal pressure, low internal 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 internal pressure, low internal pressure, or immersion.
