7.3.5 Sample extraction
After the inspection batch is formed, the sample is randomly extracted. Small and medium-sized products are sampled after the box is sealed; large, special products and small-volume products are sampled before the box is sealed. 7.3.6 When the inspection batch is judged to be unqualified, the product shall be reworked and re-classified by the delivery party. After the unqualified products are eliminated, it can be inspected again. 7.4 Type inspection
QB/T1634
Type inspection is conducted every three months. In case of any of the following situations, type inspection must also be conducted. Changes in product structure, raw materials, formula, and process; after major overhaul or transformation of major production equipment;
