ISO 9022-21 Optics and Optical Instruments - Environmental Test Methods - Combined Low Pressure and Ambient Temperature or Dry Heat

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ISO 9022-21 testing. This part of ISO 9022 specifies methods for testing optical instruments and instruments containing optical components for their ability to withstand combined low pressure and ambient temperature or dry heat under equivalent conditions.

The purpose of the test is to investigate to what extent the optical, thermal, mechanical, chemical and electrical performance properties of the sample are affected by the combined low pressure and ambient temperature or dry heat; Examples are instruments installed 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.

EUROLAB assists manufacturers with ISO 9022-21 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
