4 Technical requirements and test methods
4.1 Basic parameters and dimensions The basic parameters and dimensions of the plug shall comply with the regulations in Figures 1 to 3. Whether it is qualified or not, it should be measured with a measuring tool that meets the measurement accuracy. The plug of the certificate must be connected with a flexible cable with the certification mark and has the corresponding certification mark. The length of the flexible cable is according to the order requirements. Compliance is checked by observation and measurement.
4.5 The plug of the power-on test plug and the flexible cable should be connected, and there should be no following faults:
1) The disconnection of the safety lead;
2) Interchange of phase wire, neutral wire, and safety lead;
3) Short circuit between phase line, neutral line, and safety lead
Whether it is qualified or not, use a power cord plug comprehensive tester to measure whether each pole is open, short-circuited, or interchanged.
4.6 The marking plug shall have the following fixed markings:
1) Model;
2) "Cloud Ring" registered trademark;
3) Rated current; A
4) Rated voltage; V AC symbol ~.
5) Certification mark;
The logo shall be durable and legible. Compliance is checked by visual inspection of the power cord. After 15s with a cloth soaked in water by hand, then with a cloth soaked in gasoline for 15s, whether it is qualified or not, it is checked by visual inspection; the logo of concave-convex pressing can be exempted from the durable sassafras test.
