a) For products produced in batches, the number for sampling should be no less than 20% of the whole batch (no less than three units), and one unit should be selected; b) For products produced in small batches, one unit should be selected. 5.1.2 Samples in the production process
a) For products produced in batches, one to two units should be selected from the qualified parts in storage; b) For products produced in small batches, one unit should be selected or the whole machine should be disassembled for inspection (for parts of large products, the inspection record of the current product process can be used as the basis).
5.2 Judgment rules
5.2.1 All test items are only allowed to be inspected and evaluated in sampling. If any item is unqualified, no double inspection is allowed. 5.2.2 During the inspection process, the following situations are judged as unqualified items: a) The items that should be inspected are not inspected (the main items between processes can be checked according to the original inspection records); b) The physical properties, chemical properties, flaw detection, carburized layer and other items of the material cannot be inspected on site and there are no original records or test reports.
5.3 Evaluation results
5.3.1 According to the actual measurement results of the product, four indicators should be calculated: a) The qualified rate of finished product inspection items;
b) The qualified rate of assembly, painting and packaging quality inspection items; c) The qualified rate of key items of major parts;
d) The qualified rate of major items of major parts.
5.3.2 The quality level of the entire batch of products shall be evaluated according to the lowest level of the actual measurement results. 5.3.3 For a batch of products with a certain grade, the grade of each product shall not be higher than the grade set for the batch. 8
