For packaging and other auxiliary materials, the quality control department shall verify the supplier's RoHS report and confirm its conformity.4 technical requirements and test methods
4.1 basic parameters and dimensions the basic parameters and dimensions of the plug shall comply with the provisions in Fig. 1-fig. 3. Whether it is qualified or not, it should be measured by measuring tools that meet the measurement accuracy. The plug of the certificate must be connected with the flexible cable with certification mark and corresponding certification mark. The length of flexible cable shall be in accordance with the order requirements. Whether it is qualified shall be checked by observation and measurement.4.5 the pin and flexible cable of the power on test plug shall be connected, and the following faults shall not exist:1) Break of safety lead;2) Exchange of phase line, neutral line and safety lead;3) Short circuit between phase line, neutral line and safety leadIf it is qualified, use the power cord plug comprehensive tester to measure whether the poles are open circuit, short circuit or interchangeability.4.6 the following fixed marks shall be provided on the marking plug:1) Model number;2) "Cloud ring" registered trademark;3) Rated current: a4) Rated voltage: V AC symbol ～.5) Certification mark;The sign shall be durable and legible. The power line shall be inspected by visual inspection. After 15 s of rubbing with water soaked cloth by hand, and then 15 s with gasoline soaked cloth, whether it is qualified can be inspected by visual inspection; the concave convex pressing mark can avoid durable Sassafras test.
