(batch number), number, product quality certificate and this standard are hereby compiled and approved by the acceptance unit. The quality of the products received is the new product quality of this standard. Order a batch to be accepted for one-time acceptance, and different batches shall be accepted in stages. 7.3 Your batch unit shall take two pieces from less than 1 car, and three pieces from more than 1 car. Open and take out the detailed pieces. There should be no moisture and impurities on the surface. Then, you can use a glass sampling tube to extract each sample ~ 101, inject it into the sample mixer, mix it evenly, and put it into two clean frosted amber bottles with half of the cover exposed. Note the name of the manufacturer, product name, batch number, quantity and sample date on the outside of the bottle. Report it for inspection and keep the other one for reference. 7 If one of the indicators in the test results does not meet the requirements of this standard, the manufacturer can re-sample and retest together with the manufacturer. If the test results still show that the indicators are not up to standard, the whole batch of products cannot be collected. 7.5 When the supply and demand parties have disputes over the quality of the products, the two parties can negotiate to appoint a legal testing agency to be responsible for the negotiation. 8 Marking, packaging, transportation, storage. The products are placed in aluminum barrels or glass containers, and the packaging should indicate the manufacturer name, product name, trademark, batch number, net weight, tare weight, expiration date and the abbreviation of this standard. If the ordering unit has other requirements, it can reach an agreement with the manufacturer. 2. This product should be stored in a cool and dark warehouse with low humidity and wind, away from fire source, and should not contact with acid.
