IPX1-8 open waterproof testing equipmentFeatures of the equipment

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 shell protection water tests for specific products or materials is an essential key procedure.

This set of waterproof testing equipment (IPX1-8) is a standard equipment, which includes a drip device, a swing tube device, a flushing device, and a immersion device. It needs to be installed in a specially designed laboratory to conduct artificial simulated rain tests on the product. The water inlet, drainage, and waterproof facilities in the laboratory must be installed in place. The entire set of equipment shares a water tank and a PLC LCD touch screen controller for integrated control. Through water pumps, electronic flow meters, and pressure sensors, it is used to assess and determine whether the casings 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.

The entire equipment meets the requirements GB 4208-2017(IEC 60529)、GB 2423.38-2005 （IEC 60068-2-18）、 GB/T 30038-2013（ISO 20653：2006）、GB/T 4942.1-2006(IEC 60034-5)、 GB 7000.1(IEC 60598-1) wait
