Optics and photonics. Environmental test methods - Humid atmosphere containing sulfur dioxide or hydrogen sulfide1 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 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,
