Specify test items
The electromagnetic device for type test must be a formal trial-produced sample, and each test item (or test chamber) should be no less than one. All specified type test items should be qualified, and the product type test should be qualified. Products that pass the type test should be adjusted. 7.2.3 Test results and evaluation
In the type test, for items that do not constitute a safety umbrella or seriously reduce the performance indicators, except for temperature rise, if there is an error, as long as the tester can provide evidence that the error is not an inherent defect of the design, but a defect of an individual test product, the original test product will be retested for several days. If the retest is qualified, it is still considered to have passed the type test. 7.3 Periodic Tests
7.3.1 After the product passes the type test and enters the production stage, a periodic test is conducted to check the product quality and stability. 8

Each test item (or test sequence) should be no less than one unit, and all the specified inspection items must be met. If one unit or item fails in the test, the item shall be retested according to the original quantity. If all the re-test results are qualified, the periodic test can still be considered qualified: if one item fails during the test, the periodic test is considered unqualified.
