Rain test; 20.Test Background

The damage caused by natural rainwater to products and materials causes inestimable economic losses every year. The damage mainly includes corrosion, fading, deformation, strength reduction, swelling, mold, etc. Electrical products, in particular, are prone to fires due to short circuits caused by rainwater. Therefore, it is a key procedure to conduct an enclosure water test for a specific product or material.
The rain test can be used to assess and determine whether electrical, electronic products and automotive parts and seals can ensure good working performance of the equipment and components after or during the water test. The rain test can completely simulate the external rain environment and fully test the impact of the external rain environment on the product. It is divided into a swing tube type water test and a sprinkler type water test.
Zhongke Testing Environmental Reliability Experiment Center has various climate environment simulation test equipment and is equipped with rain test capabilities. It provides professional rain test services for various types of electrical and electronic products, aviation, lighting fixtures, electrical cabinets, electrical components, automobiles and other products.
