4.F1 The tungsten boat is clean and has a light-bearing property. The surface of the boat is allowed to have a slight oxidation color but no dark spots or black spots. The electrolytic disc is allowed to have an area of ​​less than 211m* before the end of the light spot. 4.62 The surface of the boat should not have cracks, delamination, cracks, missing edges and corners, and there should be no hair on various parts. 4.7 The physical properties of the board selected by the contractor shall meet the requirements of 3BT5. 5 Test method 5.1 The test results of 4.1 are analyzed according to the relevant standards in 342.1-. 52 The standard dimensions of the side plates 4.2 The following dimensions shall be measured with a ruler of 0.02mm and 0.0mm and a ruler of 0.53 The dimensions shall be measured according to 4196. 5.4 The weight of other plates shall be weighed with a human scale (1.2g). 5.5 The special measurement of the plate can be omitted if the chemical composition of the plate is qualified. 5.6 The surface quality of the plate shall be inspected at regular intervals. 6 Inspection regulations 6.1 Inspection batches must be composed of products of the same tax category and of the same components, three parts and continuous production from different countries. 6.2 Receipt inspection 6.2.1 The products shall be inspected and certified by the Chinese inspection department in accordance with the safety requirements of the vehicle standards. The product must meet the requirements of this standard. 6.2.2 The product must be inspected and accepted within two months after receipt. If the inspection result does not meet the requirements of this standard, the supply and demand parties shall negotiate to resolve the issue.
6.3 Decision-making strategies and judgment rules
63.1 Inspection of chemical composition: Randomly select one sample from a batch of materials for chemical composition analysis. If it does not meet the requirements, additional samples shall be taken for analysis and the average value shall be taken. If it still does not meet the requirements, the batch of materials shall be unqualified. 6.3.2 The specifications of tungsten boats shall be inspected before further inspection. 63.3 Inspection of the quality of each boat: Select one sample from each batch for chemical measurement. If the result is not satisfactory, double the sample shall be taken for measurement. If two of the samples are unqualified, the batch of materials shall be rejected. 63.4 The unqualified and qualified samples will be randomly selected from 100 samples for determination. If there are 3 unqualified samples among the 10 samples, the samples will be deemed unqualified. 6.3.5 For the general purpose, 100% control shall be carried out, including packaging, marking, transportation and storage. 7.1 Packaging. The qualified samples shall be packed in kraft paper and then packed into plastic bags. Each bag shall be packed with 21 bags, and each box shall be packed with 4 bags. The inner packaging shall be filled with shockproof paper. 7.2 Steel label. 7.2.1 The inner packaging shall have a label or product certificate and shall indicate: Sample name.
