ISO 9022-23 Optics and Photonics - Environmental Test Methods - Low Pressure Combined with Cold Ambient Temperature and Dry or Moist Heat

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ISO 9022-23 testing. This standard covers methods for environmental testing of optical instruments, including additional assemblies from other fields (e.g. mechanical, chemical and electronic devices), for their ability to resist the effect of low pressure combined with cold under equivalent conditions.

This standard applies to optical instruments, including additional assemblies from other fields, designed to be operated or carried in high mountain areas or on aircraft or missiles.

The purpose of the test is to investigate to what extent the optical, climatic, mechanical, chemical and electrical (including electrostatic) performance properties of the sample are affected by the combined low pressure and low, ambient or high temperature. Additionally, the additional effects of moisture condensation and freezing on the device or components can be determined. Examples are instruments mounted on aircraft or missiles, mounted externally, or carried inside aircraft or flying objects that do not provide any pressure compensation.

Optical instruments are affected by a number of different environmental parameters during their use, which they must withstand without significant reduction in performance.

The type and severity of these parameters depend on the conditions of use of the device (e.g. in the laboratory or workshop) and its geographical location. Environmental effects on optical instrument performance in tropical and subtropical regions are completely different from those found when used in polar regions. Individual parameters cause a variety of different and overlapping effects on device performance.

The manufacturer strives to ensure that the devices withstand the possible rigors of the environment throughout their lifetime, and the user naturally expects this. This expectation can be evaluated by exposing the device to a set of simulated environmental parameters under controlled laboratory conditions. The severity of these conditions is often increased to achieve meaningful results in a relatively short period of time.
