High and low temperature test chamber test standard for automotive exterior lighting

The GB/T10485 standard mentions the use of high and low temperature alternating humid heat test chambers to determine the temperature resistance of external lighting and light signaling devices for automobiles and trailers
.

The following is the specific test method summarized by Liuqin Technology, see: First, the sample: prepare two lighting or light signal devices
.

Second, the test method: the specimen is placed in the normal working position into the test chamber, and goes through 5 test cycles, each test cycle composition includes humid heat 38 °C to maintain 16h, relative humidity of 95%, low temperature -30 °C high temperature 60 °C to maintain 4h, temperature conversion rate of 0.
6 °C / min ~ 4.
0 °C / min, cycle start temperature 20 °C; Third, the test results are determined: after the test, the visual inspection specimen should be non-corrosive, the mirror and the light distribution mirror should not be deformed and not foamed, and the light distribution performance should meet the requirements of
relevant standards.

Liuqin Technology is specialized in the production of high and low temperature alternating humid heat test chamber and a series of environmental test equipment manufacturers, the company has many years of environmental test chamber, testing machine production experience, often with many domestic and foreign enterprises cooperation, products are exported to many countries and regions
in the world.
