ISO 9022-2:2015

Overview

ISO 9022-2:2015 - "Optics and photonics - Environmental test methods - Part 2: Cold, heat and humidity" defines laboratory methods to assess how optical instruments (and instruments containing optical components plus additional assemblies from other fields) resist temperature and humidity influences. The standard’s purpose is to determine the extent to which optical, climatic, mechanical, chemical and electrical (including electrostatic) performance characteristics are affected by cold, heat, damp heat and condensation.

Keywords: ISO 9022-2, environmental test methods, optics and photonics, cold heat humidity testing, damp heat, condensation testing, conditioning methods.

Key topics and requirements

• Scope and intent: Tests simulate realistic and accelerated environmental conditions (arctic to tropical) to verify instrument robustness and lifetime performance.
• Conditioning methods: The standard specifies named conditioning methods including:
  • Method 10 - Cold (examples: temperatures from around 0 °C down to −65 °C are listed across severity degrees)
  • Method 11 - Dry heat (temperatures up to 85 °C; relative humidity
