What Is the Double 85 Test?

Double 85 test is an accelerated aging test method, which refers to the continuous test of the weather resistance, tightness and electrical performance of the product under the constant environment of 85 ° C ±2 ° C and 85%RH±3%.

The test can simulate extreme wet and thermal environment, widely used in photovoltaic components, automotive electronics, lithium batteries, LED lighting and other fields, is the IEC 60068, IEC 61215, JESD22-A101 and other international standards of the core test project.The test time is divided into four grades: 168h,504h,1000h and 2000h.

IEC 60068-2-67-2019

Common consumer electronic products such as smart phones, smart watches, etc., according to industry standards need to pass at least 500 hours of double 85 test to ensure that when used in hot flash areas are not prone to failure, such as screen failure, battery bulge, internal circuit short circuit and other problems.

For some products with high reliability requirements, such as outdoor power equipment and new energy vehicle electronic components, the test time may be extended to more than 1,000 hours.

The LIB damp heat chamber plays a key role in the dual 85 test. It adopts advanced temperature control technology, the temperature control accuracy can reach ±0.5℃, the humidity control accuracy can reach ±2.5%RH, to ensure the test environment is accurate and stable, and provide a reliable guarantee for the double 85 test. The internal space design of the damp heat chamber is reasonable, from a small volume of tens of liters, to meet the single batch test of small electronic devices, to a large volume of thousands of liters, which can be used for multi-station testing of large circuit boards and whole equipment at the same time, to meet the needs of various products.

Since the double 85 test is also widely used on photovoltaic panels, LIB has a PV test chamber specifically for the double 85 test on photovoltaic panels.
