Inspection rules
7.1 Inspection classification
Product inspection is divided into factory inspection and type inspection. 7.1.1 Factory inspection
Each batch of fillers must pass the inspection before it can be shipped. The items for strict factory inspection are 5 of this standard. 2.5.3 Items specified. 3
W.7.1.2 Type inspection
HG/T3114—1998
7.1.2.1 Type inspection should generally be carried out in any of the following circumstances: a) When the product is put into production;
b) After normal production, if there are major changes in the product structure, process, or material, which may affect the product performance; c) When the product is resumed after a long period of suspension; d) When there is a significant difference between the factory inspection result and the last type inspection result; e) When the national quality supervision agency proposes a type inspection requirement. 7.1.2.2 Product type inspection is carried out once a year, and the inspection items are all the items specified in Chapter 5 of this standard. 7.2 Sampling and judgment rules
7.2.1 Batching and sampling
The same specification of fillers produced in the same shift and under the same process conditions are regarded as a batch, and 50 samples are randomly selected from each batch of fillers. 7.2.2 Judgment rules
If any item does not meet the requirements, the same number of specimens in the 7.2, 2.1 compression strength and drop weight impact strength tests shall be taken from the same batch of products, and the performance shall be retested, and the retest results shall be taken as the final results. 7.2.2.2 In the appearance quality and outer size inspection, if they are unqualified, retest shall be carried out, and the retest results shall be taken as the final results. If the retest results are not met, the product name and manufacture shall be marked on the outer packaging. 8.2 The packing belt shall be made of carton or plastic woven. 8.3 Each packaging bag shall contain the product type
a) product name, specification and quantity:
b) product standard number;
c) product production date, inspection date
d) inspection results and inspector's seal.
8.4 Filling materials should not be transported in
8.5 Filling materials should be stored in a dry, non-
place. If the
rate still exceeds 5%, the same number of samples should be drawn from the same batch of products. If the
rate still exceeds 5%, the batch of products is considered unqualified. Name, address, specifications, quantity and "Do not press" and other signs. Good packaging
