Overview

This part of ISO 9022 specifies the methods relating to the environmental tests of optical instruments and including additional assemblies from other fields (for example mechanical, chemical, and electronic devices) under equivalent conditions, for their ability to resist the influence of combined contamination and solar radiation. "Contamination", as used in this part of ISO 9022, means the contact of optical instruments with corrosive chemical substances (hereafter called test agents). Complete instruments or assemblies are, however, not to be tested to this part of ISO 9022 except for special reasons (refer to ISO 9022-12). As a rule, representative substrates are used as specimens. The tests described in this part of ISO 9022 are designed for the selection of materials and components for instruments likely to be subjected to combined contamination and solar radiation during service life, rather than for regular production control. The purpose of testing is to investigate the resistance of an instrument, and in particular, of instrument surfaces, coatings, or synthetic materials, to a short-time exposure to the test agents combined with solar radiation.
