This part of the revision using ISO 9022-18.:1994 "Optical and optical instrument environmental test method Part 18. hot and humid, low internal pressure Test ".

The main differences between this part and ISO 9022-18.:1994 are.

- the preamble and prerequisites for the deletion of international standards;

- the standard scope was rewritten in accordance with ISO 9022-18, Chapter 1 and our standard language;

- "International Standard Part" is replaced by the words "this part";

- the normative references in Chapter 2 are replaced by current national standards;

- Suspension section of condition test.

Terminology, test range (GB/T 12085.1 -2010, ISO 9022-1.:1994, MOD) GB/T 12085.8 Environmental and optical instruments - Environmental test methods - Part 8. High pressure, low pressure, immersion (GB/T 12085.8-2010, ISO 9022-8.:1994, MOD)

3 Test conditions

Testing of exposed specimens under combined operating conditions is more severe than any single environmental condition test.

There are three different methods for the combination of anti-damp heat and low pressure in optical instruments.
