ISO 9022-12:2015 pdf free.Optics and photonics一Environmental test methods
This part of ISO 9022 specifies the methods relating to the environmental tests of optical instruments including additional assemblies from other fields (e.g. mechanical, chemical, and electronic devices),under equivalent conditions, for their ability to resist the influence of contamination, i.e. contact with corrosive chemical substances (hereafter called test agents).1)
However, complete instruments or assemblies are only tested as specified in this part of ISO 9022 in exceptional cases (see 5.3). Normally, representative samples such as material items or surface coatings on representative substrates are used for testing.
The tests described in this part of ISO 9022 are designed for the selection of materials and components for instruments likely to suffer contamination during service life, rather than for regular production control.
The purpose of testing is to investigate the resistance of an instrument and, in particular, of instrument surfaces, coatings, or synthetic materials, to a short exposure to the test agents.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 9022-1, Optics and photonics一Environmental test methods一Part 1: Definitions, extent of testing
3 General information and test conditions
The test shall be conducted under ambient atmospheric conditions in accordance with ISO 9022-1.
The test agents listed from each conditioning method (Clause 4) represent different chemical groups.
3.1 Specimen
Unless the testing of complete instruments or assemblies is required in the relevant specification, representative samples shall be used for testing. Representative sample sheets of at least 1 mm thickness and having dimensions as shown in Figure 1 shall be used as substrates for the testing of non-metallic coatings.
NOTE Sample sheets of 140 mm±2 mm or 280 mm±2 mm in length can also be specified in the relevant specification.ISO 9022-12 pdf download.
