3.4 Yellow Chrome-plating Fig. The user determines the test time and temperature, well the .19: Typical colour variations Housings made aluminium alloys can protected from corrosion by chrome plating.1 Type seals Connectors always consist two more parts and therefore must sealed accordingly.3.17 3. applied by immersion, spray-painting electrolytically. This problem tolerated, because yellow chrome plating is very inexpensive, and does not contain substances that are harmful health. The seal between the bulkhead mounted housing and the mounting surface stressed only once, during installation (the two parts are usually screwed together), and remains position afterwards. Different sealing levels are created, depending the housing combination. This chrome finish frequently used for EMC housings, because of its electrical conductivity.2.2). Mating forces stress the seal between the upper and the lower bulkhead mounted housing. After the seal has been exposed prolonged pressure stress, its elasticity is tested.3 Sealings 3. 3. For housings deployed very rough environments, layer powder coating applied over the chrome. The colour the coating is determined varying the process duration and type, well the layer thickness. The chrome layer consists chrome compound created with chrome containing acidic alkaline solutions. Defined samples the seal material are inserted between two polished steel plates and then compressed the dimension specified the standard.2. The type seal chosen based the required degree of protection (refer Sections 2.Hoods and Housings 33 3. disadvantage this kind coating that the colour varies considerably; yellow chrome layers range from light yellow to dark brown.
