6 Inspection rules
6.1 The product is one batch per kettle.
6.2 Sampling is carried out according to the method specified in GB5475. HG 2164—91
6.3 Each batch of products must be inspected by the quality inspection department of the manufacturer, and it is ensured that all products leaving the factory meet the technical requirements specified in this standard.
6.4 In this standard, appearance, water content, mass total exchange capacity, volume total exchange capacity, wet apparent density, transformation expansion rate, particle size and infiltration ball rate are factory inspection items; apparent true density, effective particle size and uniformity coefficient are random inspection items, which shall be inspected at least once a month. Type inspection shall be carried out in accordance with 6.6.1 in GB 1.3 6.5 The user has the right to inspect the received products in accordance with the provisions of this standard. If re-inspection is required, it should be submitted to the manufacturer within 3 months of receiving the product.
6.6 If a certain technical requirement in the inspection results does not meet the provisions of this standard, samples should be taken from twice the number of packages of the batch of products for re-inspection, and the re-inspection results should be used to determine the quality.
6.7 When the supply and demand parties have objections to the product quality, the two parties shall negotiate to resolve the issue or the statutory quality inspection department shall conduct arbitration. 7 Marking, packaging, transportation, storage
7.1 Marking
Each batch of products should have a quality inspection report, and a clear and firm mark should be on the package, indicating the product name, model, grade, batch number, net weight, production date and manufacturer name. 7.2 Packaging
