  Water resistance testing is used to verify the effectiveness of protective covers, housings and gaskets that prevent water from penetrating the product; to verify the ability of the product to meet its performance requirements when and after exposure to water; to verify any physical damage to the product due to exposure to rain; to verify t he effectiveness of any water removal devices and the effectiveness of the packaging. The waterproof test ing equipment can provide realistic simulation of various environments such as water   splashing   and water jetting   tests that electronic products and their components may be subjected to during transportation and use. In order to test the waterproof performance of various products.   According to the different effects of water on the product, there are many different test methods   for water tests, such as dripping water test , spraying water test , jetting water test , immersion water test and etc.. Differen...

Abrasion Resistance Tester/ Scratch Tester 1.  Introduction Abrasion resistance tester is designed according to IEC60950 clause 2.10.8.4 and IEC60335-1 clause 21.2 .   It is applied to do scratch test for accessible parts of solid insulation of household appliance and printed circuit boards, to ensure the material has sufficient strength to prevent penetration by sharp implements .   The scratch resistance test uses a hardened steel pin f or scratching. The end of the steel pin   should be tapered with a   apex   angle of 40 ° . The tip should be rounded with radius of 0.25 mm ± 0.02 mm. When performing the scratch test, the test pin is held at  80-85° to the horizontal , and scratches were performed at a speed of 20 mm/s ± 5 mm/s in a plane perpendicular to the edge of the conductor. The steel pin should be properly loaded so that the hardened steel pin can apply a force of 10N ± 0.5N along its axial direction. The scratch interval should be at least...

Introduction The tracking index test apparatus is designed according to IEC60112, UL746A, GB.T4207, GB 4706.1 and TMD 3628-92. On the surface of the solid insulating material, a certain voltage is applied between the platinum electrode s  (2 mm × 5 mm) , and drops the   pollution  liquid (0.1% NH4CL) with  specified droplet volume   in fixed height (35mm) for 30s to evaluate the resistance of the surface of solid insulating materials under the combined action of electric field and contaminated medium, and its   Comparative   tracking index (CT I ) and   proof tracking index (PT I)  are determined . Tracking index test apparatus is mainly used in the industries of lighting appliance, low voltage appliance, household appliance, motor, electronic appliance, instrument and etc. It is a good tool for research department, production department and QC department.
