NBN ISO 9022-9:2021

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 effects of simulated solar radiation or
laboratory weathering, which is a combination of simulated solar radiation, heat, and moisture. It is
applicable to instruments that may be exposed to sunlight during operation or unsheltered storage on
the earth’s surface, or in the lower atmosphere.
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 solar
radiation or weathering (solar radiation, heat, and moisture).
