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).

ISO 9022-1-2016 “Optics and optical instruments – Environmental test methods – Part 1: Definition, scope of test”

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.

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. In tropical and subtropical climates, the effect of the environment on the performance of optical instruments is completely different from that found when used in the Arctic region. 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 primarily based on IEC standards, modified if necessary to take into account the specific functions of the optical instrument.

ISO 9022-1-2016 “Optics and optical instruments – Environmental test methods – Part 1: Definition, scope of test”

Due to the continuous progress in various fields, optical instruments are no longer just precision designed optical products, but also include 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 functions are important, then ISO 9022 is applicable, but if other functions take precedence, then appropriate international standards in the relevant fields should be applied. There may be situations where ISO 9022 and other appropriate international standards need to be applied simultaneously.

1 Range
This part of ISO 9022 defines terms related to environmental testing of optical and photonic instruments, including other components from other fields (such as mechanical, chemical and electronic devices), and specifies the essential characteristics of testing.

2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

2.1 Environmental test

Laboratory simulations, often severe, of climatic, mechanical, biological, electrical (including electrostatic) and chemical environmental effects acting on specimens during assembly, storage, transport and handling in order to identify any changes in specimen behaviour within a short period of time

2.2 Optical Instruments

Instruments whose functions are primarily based on optical phenomena, consisting of multiple components and/or assemblies, lighting systems, instruments with light conduction, and instruments containing components and/or assemblies from other fields in addition to optical units

Example: electronic components.

2.3 Optical Components

A functional unit consists of a number of components, at least one of which has an optical function

ISO 9022-1-2016 “Optics and optical instruments – Environmental test methods – Part 1: Definition, scope of test”

2.4 Components

< Optical Instruments > The smallest unit, usually consisting of one piece and one material

2.5 Representative Samples

Samples that differ from components only in geometry

Example: optical parts or sheet metal.

2.6 Specimen

An instrument, component, assembly, or representative sample being tested

2.7 Testing

2.8 Regulation

The sum of the external influences acting on the specimen during the test, such as the method of adjustment and the severity of the application, and the sum of the internal influences arising from the operating state of the specimen, such as movement and/or temperature changes
