85 85 Test

The 85 85 test is a type of temperature and humidity testing where the specimen is exposed to an environment maintained at 85℃ with a relative humidity of 85% for a specified time period. This test is usually done on products that have a long operation life and helps to determine their life cycle.

In the 85 85 test, the specimen is placed in an environment with a temperature of 85℃ and relative humidity of 85%. The duration of the test may vary, but in general, the specimen is exposed to the 85 85 environment for as long as 1,000 hours. 

The test is also called the damp heat test and is capable of simulating the effect of 20 years of moisture exposure on a product.
