Waterproof testing device

1、 Equipment features

The damage caused by rainwater in nature to products and materials results in incalculable economic losses every year. The damage caused mainly includes corrosion, fading, deformation, decreased strength, expansion, mold, etc., especially electrical products that are prone to fire due to short circuits caused by rainwater. Therefore, conducting a shell protection water test for specific products or materials is a key procedure.

This waterproof testing equipment can be used to assess and determine whether the enclosures and seals of electrical and electronic products, various electrical appliances, and lighting fixtures can ensure good working performance of the equipment and components after or during water testing. The device can simulate the external rainy environment and fully reproduce the impact of the external rainy environment on the product.

This device is used for manual simulation of rain tests, excluding rainfall with strong wind speeds, and does not consider the large amount of water ingress caused by the temperature difference between the test sample and the rainwater temperature.

This device can provide corresponding environmental simulation and accelerated testing for scientific research, product development, and quality control.

2、 Meet the standards

The rain test chamber mainly provides various water testing environments for waterproof and reliability assessment. This equipment meets the requirements ofGB4208-2017 (IEC 60529) protection level, GB2423.38 (IEC 60068-2-18) test Ra2, GB/T30038-2013 road vehicle electrical and electronic equipment protection level (IP code), GB-T 4942.1-2006 protection level (IP code) classification of rotating electrical machine overall structure, GB 7000.1 (IEC 60598-1) general requirements and testing of lamps, and other standards' test requirements.

This anti vertical drip test device (drip box method test equipment) meets the requirementsIPX1 and 2 in GB4208; Test Ra2 in GB2423.38 (IEC 60068-2-18)
