The Role of High And Low Temperature Chambers in Environmental Testing

The high and low temperature test chamber is suitable for environmental simulation reliability tests such as high and low temperature constant and gradual changes, damp heat tests, etc. for various electrical and electronic products and other products, parts and materials.

Composition of high and low temperature environmental test chamber:
The components of the high and low temperature test chamber mainly include refrigeration, heating, control, air circulation, sensors and other systems. Capabilities include high temperature, low temperature and temperature cycle testing. In contrast, the constant temperature and humidity test chamber has an additional humidity system. Can carry out high temperature, low temperature, humidity cycle test.

Its functions mainly include: testing the operating status and performance stability of electronic components and products under different temperature and humidity conditions, evaluating the weather resistance and aging resistance of materials, simulating various extreme weather and transportation, storage and use. complex environment;

Verify the adaptability and stability of products in extreme environments, provide scientific basis for product design and production, reduce product failure rate and maintenance costs, and improve product quality and reliability. Therefore, high and low temperature test chambers have broad application prospects in electronics, aerospace, pharmaceuticals, automobiles, chemicals and other industries.

High and low temperature test chambers can be divided into “alternating test” and “constant temperature test” according to test methods and industry standards. Both test methods are upgraded and expanded on the basis of high and low temperature test chambers. High and low temperature alternating test chambers refer to It is possible to set the required high temperature, low temperature and required temperature time within the instrument parameters at one time;

The test chamber will go through the program according to the setting. The high and low temperature test chamber is making a fixed temperature, so that the test effect is closer to the natural climate, and the harsher natural climate is simulated, so that the reliability of the tested sample is higher.

Environmental testing is to expose products (including materials, components, etc.) to certain environmental conditions, and evaluate the functions/performances of components, equipment, and systems in actual transportation, storage, and use environmental conditions based on the test results.

Environmental testing can provide important information on product quality methods and is an important means of quality assurance.
Purpose:
1. By imposing pre-set environmental conditions on the product to be tested, product defects are exposed to provide a basis for product quality improvement;

2. Assess and verify the environmental adaptability of the product (environmental adaptability), function:
a. Promote the improvement of product market competitiveness;
b. Form technical barriers in international trade; c.
Weaponry has great military significance.

Environmental testing runs through the entire process of product design, research and development, production, transportation, and use. The way to provide product environmental adaptability is usually: environmental analysis→design→environmental testing→improvement→re-environmental testing→qualitative mass production

The more effective the environmental test is done, the better the improvement will be, and the more reliable and durable the product will be in use. The more realistic and accurate the environmental test, the better the reliability of the product.

Temperature Humidity Chamber | Thermal Chamber | Climate Chamber is according to IEC60068-2-1 (GB/T2423.1) and IEC60068-2-2 (GB/T2423.2), IEC60068-2-78, IEC60598-1, GB/T2423.17, GB/T5170.2, GB/T5170.5. The climate chamber is used to test the CFL/LED which meets IES LM-80-08, electricity products, automative cars, home appications and mobiles.

What is Climate Chamber?

Climate chambers is used to simulate a temperature enviromental condistions, it may also be called environmental chambers or Thermal Chamber or Temperature Chamber. You can click the below videos to learn the details and also how to operate it.
