Fast Thermal Test Chamber – Environmental Test Chamber

The test to evaluate and analyze the reliability of electronic products is called reliability test Reliability test is an activity to evaluate the functional reliability of a product in all environments such as expected use, transportation or storage within the specified service life Environmental test chamber

The products of the test chambers are widely used in industry, electronics, machinery, aerospace and other fields There are many types of environmental test chambers, and the application fields of products are also different.

Environmental equipment includes:
1. Climatic environment test equipment
The environmental factors of climate environmental equipment simulation are mainly the inherent environmental factors of nature, such as temperature, humidity, wind, rain, thunder, electricity, sunshine, etc There are also a few environmental factors, such as dust, fire and so on.

2. Mechanical environment test equipment
Mechanical environment test equipment is also called mechanical environment test equipment, and the simulated environment mostly belongs to induced environmental factors.

3. Electromagnetic environment test equipment
Electromagnetic compatibility test is a set of electromagnetic compatibility tests used to test the intensity of electromagnetic interference produced by the product to the surrounding environment and related equipment, the sensitivity of the product to the electromagnetic environment and the adaptability of the product to changes in power supply.

The temperature test chamber belongs to the climatic environment test, and the fast thermal test chamber is also one of them:
1. High temperature test
Test purpose: to assess the adaptability of outdoor lighting to storage or use under high temperature conditions
Application test equipment: high and low temperature (damp heat) test chamber
Test conditions: generally, a constant temperature stress and holding time are selected
Preferred common temperature: 200 ℃, 175 ℃, 155 ℃, 125 ℃, 100 ℃, 85 ℃, 70 ℃, 55 ℃, etc;
The preferred common test time is: 2h, 16h, 72h, 96h, etc

2. Low temperature test
Test purpose: to assess the adaptability of outdoor lighting to storage or use under low temperature conditions
Test equipment: high and low temperature (damp heat) test chamber
Test conditions: generally, a constant temperature and test time are selected

The preferred common temperatures are: – 65 ℃, -55 ℃, -40 ℃, -25 ℃, -10 ℃, -5 ℃, +5 ℃, etc;
The preferred common test time is: 2h, 16h, 72h, 96h, etc.

3. Rapid temperature change test
Test purpose: rapid temperature change is the temperature change that specifies the temperature change rate. It often simulates the regional environment with large temperature difference between day and night. It can also be used in life test to assess the appearance, mechanical performance and electrical performance of outdoor lighting
Test equipment: rapid temperature change test chamber
Test conditions:
1) High and low temperature values of temperature variation range;
2) The retention time of the test sample at high and low temperatures;
3) The rate of temperature change from low temperature to high temperature or from high temperature to low temperature;
4) Number of conditional test cycles

4. Temperature impact test
Test purpose: to assess the adaptability of outdoor lighting to the sharp change of ambient temperature The purpose of thermal shock test is basically the same as that of temperature cycle test, but the conditions of thermal shock test are much harsher than that of temperature cycle test
Test equipment: two box cold and hot shock test chamber, three box cold and hot shock test chamber
Test conditions:
1) High and low temperature values of temperature variation range;
2) The retention time of the test sample at high and low temperatures;
3) Conversion time from low temperature to high temperature or from high temperature to low temperature;
4) Number of conditional test cycles.
