introduction
ISO (International Organization for Standardization) is a global alliance of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member institution interested in a subject on which a technical committee has been established has the right to be represented on that committee. International governmental and non-governmental organizations liaising with ISO are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters of electrical standardization.

The procedures used to develop this document and those used for further maintenance are described in Part 1 of the ISO/IEC Directive. In particular, attention should be paid to the different approval criteria required for different types of ISO documents. This document has been drafted in accordance with the editing rules of ISO/IEC Directive Part 2 (see iso.org/directives).

Please note that certain elements of this document may be subject to patent rights. ISO is not responsible for identifying any or all such patents. Details of any patent rights identified during the preparation of the document will be found in the introduction and/or in the list of patent claims received by ISO (see iso.org/patents).

Any trade names used in this document are provided for the convenience of the user and do not constitute an endorsement.

introduce
Optical instruments are subject to many different environmental parameters during use, which need to be resisted without significantly degrading performance and remaining within prescribed specifications.

ISO 9022-9-2015 Optics and optical instruments – Environmental test methods – Part 9: Solar radiation and weathering

The type and severity of these parameters depend on the conditions under which the instrument is used (for example, in a laboratory or workshop) and its geographical location. The environmental effects on the performance of optical instruments in tropical and subtropical regions are completely different from those found when used in the Arctic. Each parameter will have different overlapping effects on the performance of the instrument.

Manufacturers try to ensure that, naturally, users expect the instrument to be resistant to the rigors that its environment can bring throughout its life cycle. This expectation can be assessed by exposing the instrument to a range of simulated environmental parameters under controlled laboratory conditions. The severity of these diseases is often increased in order to achieve meaningful results in a relatively short period of time.

To evaluate and compare the response of optical instruments to appropriate environmental conditions, ISO 9022 contains detailed information on many laboratory tests that reliably simulate a wide range of different environments. These tests are mainly based on IEC standards, modified if necessary to take into account the special functions of the optical instrument.

Due to the continuous progress in various fields, optical instruments are no longer just precision designed optical products, but also contain other components from other fields, depending on their range of application. Therefore, the main functions of the instrument will be evaluated to determine which international standard should be used for testing. If optical functionality is important, ISO 9022 applies; However, if other functions take precedence, appropriate international standards in the relevant field should be applied. There may be situations where ISO 9022 and other appropriate international standards need to be applied simultaneously.

ISO 9022-9-2015 Optics and optical instruments – Environmental test methods – Part 9: Solar radiation and weathering

1 Range
This part of ISO 9022 specifies methods relating to environmental testing of optical instruments, including other components from other fields (such as mechanical, chemical and electronic equipment) that, under the same conditions, are resistant to the effects of simulated solar radiation or laboratory weathering, which is a combination of simulated solar radiation, heat and moisture. It is suitable for instruments that may be exposed to sunlight during operation or stored without shelter on the Earth’s surface or in the lower atmosphere.

The purpose of the test is to investigate the extent to which the optical, climatic, mechanical, chemical and electrical (including electrostatic) performance characteristics of the specimen are affected by solar radiation or weathering (solar radiation, heat and moisture).
