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
