6.1 Each batch of products is a batch.
6.2 Sampling is in accordance with GB 5475 The method specified in it. 6.3 Each batch of products must be inspected by the quality inspection department of the manufacturer, and it should be 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 gold exchange capacity, neutral salt decomposition capacity, wet apparent density, resin particle size less than 0.315mm and ball rate after grinding are factory inspection items. Wet true density, resin particle size of 0.315~1.25mm, effective particle size, and uniformity coefficient are random inspection items. The inspection shall be carried out at least times a month. Type inspection shall be carried out in accordance with the provisions of 6.6.1 of GB1.3. 6.5 The user unit 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 There is a technical requirement in the inspection results If it does not meet the requirements of this standard, samples should be taken from twice the number of packages of the batch of products for re-testing, and the grade should be determined based on the re-testing results.
6.7 When the supply and demand parties have disputes over the quality of the products, they shall be resolved through negotiation or the statutory quality inspection department shall conduct arbitration. ?Marking, packaging, transportation, storage
7.1 Marking
Each batch of products shall have a quality inspection report. Each package shall have a clear and firm mark indicating the product name, model, grade, batch number, net weight, production date and manufacturer name. 7.2 Packaging
