6.3.1 Sampling method for type inspection: During batch production, three-sliding windows are randomly selected from the products for type inspection on a regular basis, and the requirements of various technical indicators are used as the basis for determining qualified products. When one of the items does not meet the requirements, double sampling and re-inspection should be carried out. If the item is still unqualified, the batch of products is judged to be unqualified.
6.3.2 Sampling method for factory inspection: Randomly select 5% according to the project contract number, and no less than 3 models. When one of them is unqualified, double sampling should be carried out. If one of them is still unqualified, all of them should be repaired and can only be shipped after re-inspection. 6.4 When the sliding window leaves the factory, it should have a product inspection certificate. 7 Marking, packaging, transportation and storage
