6 Inspection rules
Q51772-93
6.1 Each batch of finished products of propionic acid carbendazim shall be supervised by the production inspection department. The manufacturer shall ensure that all products leaving the factory meet the requirements of this standard. Each batch of products leaving the factory shall be accompanied by a quality certificate, which shall include: small name, product name, trademark, factory date, batch number, net weight, product quality certificate and standard abbreviation of this standard. 6.2 The acceptance unit has the right to confirm the various specifications of this standard and inspect whether the quality of the products received meets the requirements of this standard. The batch numbers of 2016-2017 are inspected and accepted for the first time, and different batch numbers are inspected and accepted separately. The packaging units of the 2016 batch are less than 1 box and the tax is collected in batches of 1 (bottle). When opening the package to take out the milk, check the appearance and see if there is any moisture or impurities. After heating, filter it evenly, then use a glass sampling tube (bottle) to absorb 0-1 μm of the sample, inject it into a mixer and mix it evenly, and put it into two small bottles standing by the cold detector. Note: "manufacturer name", "product name", "batch number", "date of collection", one bottle for inspection, and one bottle for confidentiality.
6.4·If one indicator in the acceptance invoice does not meet the requirements of this standard, the manufacturer may review and re-test it together with the manufacturer. If the annual inspection result still fails, the product batch will be re-accepted. 6.5 When the supplier and the manufacturer have disputes over the quality of the product, the two parties may jointly propose a solution and invite the inspection agency to assist. The cost shall be borne by either party.
6.6 Blood test, loss Gas, acid value, phenol content or other parameters are factory inspection indicators. Density, washing volume and solubility are type inspection indicators and are inspected once every year.
7 Marking, packaging, transportation and storage
7.1 The products are packed in galvanized barrels or glass barrels. The outside of the packaging is marked with: product name, manufacturer, trademark, batch number, net weight, export date, label number and related packaging marks. If there are special requirements for individual orders, they can be negotiated with the manufacturer. 7-2 The products should be kept away from rain and foreign air pollution during transportation. It is strictly forbidden to transport with acids, radiants, etc. 7.3 The products should be stored in a non-flammable, ventilated and cool warehouse to prevent foreign air pollution and stay away from fire sources. 7.4 The warranty period of this product is one year if the transportation conditions are met, the packaging is received and the product is unsealed. 5
