8.1 Standard state
The content of product marking includes:
Product model mark, product standard number;
Production date;
Product number:
Manufacturer name, address or trademark.
8.2 Packaging
Test method
Inspection type
Type inspection
Export inspection
Eddy current detectors are packed in boxes, and the packaging icons and signs should comply with the provisions of GB191: The technical documents carried with them when leaving the factory include product manuals, certificates of conformity, packing lists, etc. 8.3 Transportation
Eddy current detectors can be transported by sea, land, or air. 8.4 Storage
Eddy current detectors should be stored in a ventilated warehouse with a temperature of -40℃-70℃, a relative humidity of less than 90%, and no corrosive gases and strong magnetic fields. If the ground is damp, it should be placed on a wooden board with a height of 30cm to 50cm.3—2002
Use the distortion analyzer to test the distortion coefficient of the standard sensor and the eddy current detector under this state respectively; the distortion coefficient of the eddy current detector under test can be calculated by formula (3) (3)
Where:
D——Distortion coefficient of the eddy current detector under test: L—True coefficient of the standard sensor;
1) Distortion coefficient reading of the eddy current detector under test: D—Distortion coefficient reading of the standard sensor:
6.7.3 The test result shall meet the requirements of 5.1. 6.8 Transverse natural frequency f
The transverse natural frequency of the eddy current detector shall be tested in reverse according to the point method specified in SY/15046.1, and the test result shall meet the requirements of 5.1. 6.9 Insulation resistance R;
The insulation resistance R of the eddy current detector shall be tested according to the method specified in SY/T5046.1, and the test results shall meet the requirements of 5.1.
6.10 Reliability
The reliability test of the eddy current detector shall be carried out according to the requirements of 5.2 and refer to the method specified in SY/T5046.1. The test results shall meet the requirements of 5.2.
7 Inspection rules
7.1 Type inspection
7.1.1 Type inspection shall be carried out in the following cases: - New product finalization identification; - After formal production, when the structure, process and materials have major changes that may affect the performance; - When the product is discontinued for more than one year and resumed production; - The inspection results are consistent with the second type Or when there is a big difference in the inspection; when the superior quality supervision agency requires it. 7.1.2 See Table 4 for type inspection items.
7.1.3: The specimens for type inspection shall be randomly selected from the trial samples or batch products according to the provisions of (13/T2829, adopt a sampling plan of 10 times, the discrimination level, the unqualified quality level RQL, etc. 10, the qualified judgment number A, equal to 1, the unqualified judgment number R, etc. Ding 2: Reliability test shall be carried out according to the provisions of GB/T2829, adopt a sampling plan of once a month, the discrimination level P1, the unqualified quality level RQL, etc. 25, the combined judgment number A, etc. 1, the unqualified judgment number R, etc. Ding 2: 7.1.4 The samples shall be inspected according to the requirements specified in 5.1, 5.2, and 5.3. The product shall be taken as the unit , respectively, the total number of unqualified products is accumulated. 7.1.5 According to the inspection results of the samples, if the total number of unqualified products found in the detailed book is less than or equal to the qualified judgment number A, the batch of products is qualified; or if the total number of unqualified products found in the sample is greater than or equal to the unqualified judgment number R, the product is judged to be unqualified.
7.2 Factory inspection
7.2.1 Factory inspection items 1 See Table 4.
7.2.2 Each full current detector is tested according to the inspection items specified in 7.2.1. If one or more indicators are unqualified, the eddy current detector is judged to be unqualified, and the unqualified products shall not be shipped to the factory. 7.2.3 Unqualified products are allowed to be returned for repair and re-inspected according to the provisions of 7.2.2. 5046.3—2002
