Audio and video recording and playback product environmental testing

Environmental testing for audio and video recording and playback products is a test based on the adaptability of the product to the expected working environment, including the ability to withstand harsh storage and transportation environments without damage and the ability to work normally under reasonable extreme environmental conditions.
The Zhongke Testing and Reliability Experiment Center has environmental testing capabilities for various audio and video recording and playback products, and provides professional low-temperature testing and other environmental testing services for broadcast radios, radio and television receivers and other products.

Broadcast radios, radio and television receivers (including CRT receivers, LCD receivers, PDP receivers, etc.), tape recorders and other audio and video recording and playback products, audio power amplifiers (amplifiers)

Environmental testing for audio and video recording and playback products includes climatic testing and mechanical testing. The climatic testing is performed first, and then the mechanical testing is performed. Climatic tests and mechanical tests should be carried out on the same sample.
1. Climate test sequence
a) High temperature load test;
b) High temperature storage test;
c) Constant heat and humidity test;
d) Low temperature load test;
e) Low temperature storage test;
fTemperature change test;
g) Low pressure test.
2. Sequence of mechanical testing
a) Sweep frequency vibration test;
0 b) Crash test;
1 c) Drop test.
