Introduction
Optical and photonic instruments are widely used in various fields of national economy and international science and technology, due to the very complex environmental conditions of their use and transportation.
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.

3 Terms and Definitions
There are no terms and definitions that need to be defined in this document.
4 Test conditions
4.1 The sample is exposed in a test chamber (chamber) with regulated air pressure or equipped with air circulation.
4.2 The temperature in the effective working space of the test box (chamber) should be uniform everywhere, and should be consistent with the value of the control point.
The condensed water should avoid dripping on the sample.
4.3 When testing the heat dissipation samples, the number, installation method and location of temperature sensors should be specified in the relevant specifications.
Warning. Personnel entering a test chamber (room) with a dew point temperature equal to or greater than 38°C must wear breathing apparatus (eg. Condition Test Method
12, 13 and 16).
5 Condition Test
5.1 General
The temperature of each part of the sample should reach a temperature difference of less than 3K from the temperature of the test chamber (room) to start the test. For heat dissipation samples, in
The temperature change of the sample in a temperature-stabilized test chamber (chamber) does not exceed 1K per hour as the start (or end) of the exposure period or residence time.

5.2 Constant stress state
5.2.1 General
During exposure of the specimen to the constant stress state, the temperature change should be very slow to prevent damage to the specimen. When using Condition Test Method 11 or 12,
