Dry heat environment test for mechanical products

The main effects of dry heat environment on mechanical products are: insulation failure due to high ambient temperature; thermal protection device electrical appliances may not operate due to high ambient temperature; temperature differences in dry tropical areas are large, and outdoor materials are prone to aging and failure; desert transportation conditions are harsh and packaging is easily damaged, etc.
Therefore, after the mechanical products used in dry tropical areas pass the basic performance test, corresponding environmental test items should be selected based on the sensitivity of various products to dry and hot environmental factors, and artificial simulated environmental tests should be conducted on the products. Dry heat environment testing of mechanical products can select different test items based on the impact of environmental factors.
Zhongke Testing Reliability Experiment Center has various environmental testing capabilities for mechanical products and provides professional dry heat environment testing services for mechanical products.

General purpose mechanical products for use in hot and dry climate zones. The major categories of products include agricultural machinery, internal combustion engines, engineering machinery, lifting and transportation machinery, heavy machinery, petrochemical general machinery, electrical products, instruments, machine tools and general parts. Dry heat mechanical products include dry heat type, dry heat outdoor type, and dry heat desert type.
