Optics and photonics. Environmental test methods - Resistance to drip or rain Ingestion-build-258901 7 Physical (PHY) layer specification1 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 drip or rain. The purpose of testing is to investigate to what extent the optical, climatic, mechanical, chemical, and electrical (including electrostatic)
