There are various environmental conditions, such as physical, chemical, biological, climatic and electrical, which will make optical and photonic instruments The performance of the device has changed and it cannot function properly. In view of the above reasons, in order to ensure the quality of optical and photonics instrument products, it is necessary to simulate a variety of complex changes in environmental conditions. It is necessary to conduct tests on optical and photonics instrument products to assess their ability to withstand harsh environmental conditions, so GB/T 12085 includes test conditions, Conditional tests, test procedures, environmental test markings, etc. At the same time, since there are many environmental conditions and they belong to different types, in order to facilitate the For the implementation of the standard, GB/T 12085 is to be divided into 15 parts according to the type of environmental conditions. --- Part 1.Terminology, test scope.

See Appendix A for a suitable test setup. During the test, the sample should not be directly exposed to sunlight, and there should be no condensation in the test chamber (room) or the sample itself. Therefore, in the test Before the test chamber (chamber), the sample should be heated to 2K or 3K higher than the preset test chamber (chamber) temperature. If multiple specimens are tested simultaneously, the The samples or between the samples and the test chamber (chamber) walls should not be in contact with each other. The sample volume should not exceed 50% of the test chamber (chamber) volume (exposed area). After the start of the test, the sample should reach the required test conditions within 2h. During the required exposure time, the test should not be interrupted. when test gas When the body is changed, the test gas used last time should be completely exhausted from the test chamber (chamber). Absorbing sulfur dioxide should not be used in the test chamber (room). and hydrogen sulfide materials.5 Condition Test5.1 General The specified exposure time should start from reaching the required test conditions in the test chamber (chamber). 5.2 Condition Test Method 41.Moist Air Containing Sulfur Dioxide (SO2) Condition Test Method 41.See Table 1 for severity levels of humid air containing sulfur dioxide (SO2). ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 12085.20-2022_English be delivered?Answer: Upon your order, we will start to translate GB/T 12085.20-2022_English as soon as possible, and keep you informed of the progress.
