After 10,000 times, the external penetration test shall be carried out again, and the external penetration shall not exceed the specified value. 1.4 The external surface must be plated to prevent the coating from slipping and scratching. 4.5 New parts must be inspected with a certificate of conformity. 5. The parts must be cleaned and lubricated before assembly.
2. The parts such as the guide and the parts must not be damaged by scratches, collisions, or other mechanical problems. After assembly, the parts must be free of jams, and the labels must be clear and firmly placed. 4.7 The new parts must be painted with a clean surface. 5. Test methods and inspection rules
5. Each plug cylinder must be tested before leaving the factory. 5.2 If any of the following conditions are met, a product type test must be carried out. The number of products for type test is set at one unit. One unit is tested for full performance, and the rest are tested for performance. bZxz.net
