E Inspection rules
QB1774-83
6,1 Each batch of finished butyric acid products shall be inspected by the inspection department of the manufacturer. The manufacturer shall ensure that the products meet the requirements of this clause. Requirements. Each batch of products leaving the factory shall be accompanied by a quality certificate, which shall include the manufacturer name, product name, trademark, production date or batch number. The net weight, product quality and the certification number required shall meet the standards set out in this standard. 6.2 The acceptance unit has the right to confirm whether the products received meet the requirements of the standard according to the provisions of this standard. Each batch number shall be inspected once: different batch numbers shall be inspected separately. 0.3 For each batch, 200 barrels (bottles) or less shall be drawn, and 100 boxes (bottles) or less shall be drawn. When sampling outside the store, external inspection shall be carried out. There should be no small changes and heavy, and then the air should be fully vibrated. Then use the modified tube to absorb 10D-200nl of the sample, mix it evenly with the mixing spoon, and put it into two streams. In the frosted glass, indicate on the bottle: manufacturer name, product name, batch number, number and receipt date, one bottle for inspection, and one bottle for future reference.
64 If one of the indicators does not meet the requirements of this standard, you can refer to the manufacturer to add a new final resistance test. If the re-test results still have unqualified indicators, then the batch The product cannot be accepted. 6.5 When the supplier or demander has objections to the product quality, the two parties may work together to resolve the issue or invite the inspection team to conduct a type inspection, and the two parties shall bear the cost.
6. Color, aroma, acid value and phenol content are the inspection indicators. Density, refractive index and solution shall be the inspection indicators, and the inspection shall be changed every hour.
7 Marking, packaging, transportation and storage
7.1 The butyric acid factory shall put the butyric acid brand in the bottle or insert the butyric acid brand, and the packaging shall be marked with the product name, production, trademark, batch number, weight, quantity, standard reduction and related packaging marks. 1. The unit storage requirements of the goods shall be agreed with the qualified manufacturer; otherwise, the standard shall be agreed with the qualified manufacturer.
