BS ISO 9022-9:2016 pdf free.Optics and photonics一Environmental test methods
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).

A radiation source capable of generating irradiance as specified in Table 1 on the specimen surface or in a plane specified in the relevant specification is installed in a heated test chamber. The data shall include any radiation reflected from the test chamber walls but not infrared radiation emitted from the chamber walls on account of the wall temperature.
Ozone generated during exposure shall be removed from the test chamber.
The position and mounting of the specimen, the characteristics of its support and the location of the test points for measuring the radiation and the temperature within the exposure zone shall be specified in the relevant specification.BS ISO 9022-9 pdf download.
