This standard specifies the method of testing opticalin struments in an environment under the influence of mechanical stresses. The tests are designed to assess the performance variation of the instrument when it is subjected to various mechanical stresses (e.g. vibration, impact, etc.). The standard includes detailed evaluation of Optical inspection, climate, mechanical, chemical and electrical performance to ensure that the instrument can maintain its functionality and Stability under different operating conditions. ISO 9022-3:2015 replaces the previous version and incorporates the latest revisions to suit the needs of modern opticalin struments. The standard specifies the test method to ensure that the equipment can withstand the potential effects of mechanical stresses in actual use, thus guaranteeing its long-term Reliability and performance Stability.
