About This Item

 

Full Description

This part of ISO 9022 specifies methods for the testing of optical instruments and instruments containing optical components, under equivalent conditions, for their ability to resist combined low pressure and ambient temperature or dry heat.

The purpose of the testing is to investigate to what extent optical, thermal, mechanical, chemical and electrical performance characteristics of the specimen are affected by combined low pressure and ambient temperature or dry heat; examples are instruments which are installed or transported inside aircraft or flying objects not providing any pressure equalization.
