7.1 Classification of inspection and test
The inspection and test of the electric drive are divided into the following types: a) Type test:
b) Periodic test;
c) Factory test: Routine test, factory sampling test, etc. Type test
The purpose of type test is to verify whether the design and performance of the solenoid meet the requirements of this standard. Type test is required for the development of new products or the re-trial production of new products. Normally, the type change test only needs to be carried out once. However, when the product changes in design, process, materials and structure that may affect its working performance, the whole test or relevant preparation purpose 7.2.1 Type test items and sequence report 8 provisions. 7.2.2 Type test rules
The electric irons to be tested for type testing must be samples of pre-production. Each test item (or test sequence) should be no less than three units. All the specified type test items must be qualified before the electric irons can be considered qualified for type testing. Only products that have passed the standard test can be submitted for adjustment. 1. 2.3 Test results and strict regulations
In the type test, the appearance that does not constitute or seriously reduces the performance index is considered to be qualified. In addition to the temperature rise and shell protection items, if there is an error! The manufacturer must be able to provide clear evidence to show that the error is not an inherent defect in the design, but is caused by the defects of individual products. The original test items are tested. If the test is qualified, it is still considered to be qualified. 7.3 Periodic tests
T.3.1 After the product has passed the test, it shall be subjected to regular tests to check the quality of the product: 7.3.1.1 Periodic tests shall be conducted once every two to five years. .TB/T 10159-1999
7.3.1.2 The date and sequence of periodic test items shall be as specified in Table 8. Table type test, periodic test items and content of the test items: material, sea system, gas direction, i.e. (cup, forget, install, tt|| 2. Assembly dynamic, shape, size, main plug, grinding size, full electrical performance test, power test, suction test, sensitive interception flow rise test, wet heat test, temperature storage test, machine condensation test, external force test, etc. Note: external charging level test is only done on behalf of the cloud rules. 7.3.2 Regular or monitoring rules 5.2.1, 5.2.2

Type test
The periodic test must be randomly selected from the qualified products. Each test item or test sequence should be no less than one: All the specified test items are qualified. If only one unit fails in the test, it is allowed to retest the item and the original number of samples. If the retest or the whole set is qualified, it can be considered that the periodic test is qualified. If another unit fails in one item in the retest, it is considered that the test is unqualified.
7. 4.4. Routine test Routine test is the test and inspection that the manufacturer must carry out before the electronic module leaves the factory. Its purpose is to check the defects of materials, process and installation. 7.4.1.1 Routine test items and test methods are shown in Table 9. 7.4.1.2 Routine test items and test methods are shown in Table 9. 7.4.1.3 Routine test items and test methods are shown in Table 9. 7.4.1.4 Routine test items and test methods are shown in Table 9. 7.4.1.5 Routine test items and test methods are shown in Table 9. 7.4.1.6 Routine test items and test methods are shown in Table 9. 7.4.1.7 Routine test items and test methods are shown in Table 9. 7.4.1.8 Routine test items and test methods are shown in Table 9. 7.4.1.9 Routine test items and test methods are shown in Table 9. 7.4.1.10 Routine test items and test methods are shown in Table 9. 7.4.1.11112 Routine test items and test methods are shown in Table 9. 7.4.1.213 ... 4.7、Factory sampling test
