Harmonic currents

2.3 Initial factory review

2.2.1 Review content: the contents of the factory review for the factory's quality assurance capability review and product consistency checks.

2.2.2 Product consistency check 1) the certification of the product logo and the type test report should be the same;

2) the structure of the certified products (mainly related to the safety and electromagnetic compatibility performance of the structure) should be the same as the prototype of the type test;

3) certified products used in the safety parts and the electromagnetic compatibility performance of the main components should be the same as the type test declared and certified. Type test declared and confirmed by the certification body consistent.

2.2.3 Initial factory review time: In general, the type test is qualified, and then the initial factory review

2.4 Evaluation and Approval of Certification Results
