What is the performance index standard of sand and dust test chamber？
Sand and dust test chamber, also known as simulation sand and dust test chamber, refers to the equipment used for the simulation test of sand and dust environment for the products of electronic products, automobile, aviation, chemical industry and other industries. Its performance index standards usually include the following aspects:The first is the temperature range and stability, the general requirements of the sand and dust test chamber temperature range between -20 ℃ ~ +60 ℃, at the same time require the test chamber temperature change is less than ± 2 ℃.
Second is the humidity range and stability, the humidity range of the test chamber is generally required between 20% ~ 98%, the humidity change is less than ± 5%.
The third is the range and stability of gas sand concentration, gas sand concentration is generally required between 2 ~ 5kg/m³, stability requirements of sand and dust test chamber for a long time running down, the amount of fluctuations in the concentration of sand and dust is less than ± 10%.
Finally, the sealing and protection performance of the test chamber, the test chamber must maintain a high degree of internal sealing to prevent sand and dust spillage and harm to the test article. At the same time, the test chamber circuit and control system must have good protection performance to ensure the accuracy and stability of the test.
In short, sand and dust test chamber is an important test equipment, which has been widely used in various industries. The strict requirements of its index standards effectively guarantee the accuracy and stability of the test, which can help manufacturers and users quickly understand the durability and reliability of the product, and promote the improvement of product quality and market competitiveness.
