    Environmental Test

    Introduction of Environmental Tests

    Environmental test is a method for testing quality of raw materials, semi-finished products and
    finished products by simulating various environmental climates for verifying if materials and
    products reach the quality objectives expected in R&D, designing, and manufacturing by
    various environmental testing equipments. It is widely used in different fields, such as aviation,
    aerospace, military, shipbuilding, electrical industry, electronics, medical industry, photovoltaic
    industry, lighting industry, petrochemical, and automobile, etc. The main applications of
    environmental tests in enterprises are in research test, stereotype test, production inspection test,
    product acceptance test, safety test and reliability test.
