ISO/DIS 9022-7

Optics and photonics — Environmental test methods — Part 7: Resistance to drip or rain

Scope

ISO 9022-7:2015 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 drip or rain.
The purpose of testing is to investigate to what extent the optical, climatic, mechanical, chemical, and electrical (including electrostatic) performance characteristics of the specimen are affected by drip or rain. Contamination of drip or rain water due to impurities in the air is to be ignored for the purposes of ISO 9022-7:2015.
