The inspection and test of the lead wire are as follows: ) Type test:
b) Optical incubator:
) Exit test: Routine test, exit sampling test. 7.2 Type test
The purpose of type test is to verify whether the design and performance of electromagnetic devices meet the requirements of this standard. Type test is a test that must be carried out by new product development units or re-trial production units. Generally, type test only needs to be carried out once, but when the product changes in design, technology, materials and structure that may affect its working performance, all or related items of type test need to be carried out again.
7. 2. 1 Type test items and sequence shall be in accordance with the provisions of Table 8. 7.2.2 Rules for Type Test
The electromagnets to be tested for type test must be the samples of formal trial production, and each test item (or test sequence) should be no less than 11. All the specified type test items should be qualified, and it can be considered that the type test of the magnet is qualified. The qualified type test can ensure that the product can be guaranteed. 7.2.3 Test results and evaluation
The type test shows that the items that do not pose a threat to occupational safety or seriously reduce the performance indicators are not included in the temperature rise and the items without protection. If there are errors, as long as the manufacturer can provide sufficient evidence to show that the error is not a design defect, but a defect of a single test product, it is allowed to test the original test product as a whole, and the test quality is still considered to be qualified. 7.3 Periodic test
7.3.1 After the product type test is completed and enters the stable production stage, a periodic test is carried out to check the stability of the product. 7.3.1.1 stipulates that the test should be carried out every 5 years. 7.3.1.2 The periodic test items and sequence shall be in accordance with the provisions of the table.
