                                    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.
