6 Inspection rules
1782-93
6, below Each batch of finished products shall be inspected by the inspection and supervision department of the manufacturer. The manufacturer shall ensure that all the products leaving the factory meet the requirements of this standard. The products leaving the factory shall be accompanied by a quality certificate with the manufacturer name, product name, trademark, production, batch number, net weight, product quality certificate code and product abbreviation of this standard. 6.2 The receiving unit shall inspect whether the quality of the received products meets the requirements of this standard in accordance with the provisions of this standard. 6.3 Take two bottles (bottles) from each selected packaging unit (less than 10 units) and three bottles (bottles) from each 10 units (new units). When opening the package for sampling, check the appearance of moisture and impurities, then shake it to make it fully wet and evenly mixed. Collect 60-1m1 of sample from each bottle (bottle) through a sample tube, inject it into a sampler and mix it evenly. Put it into two clean and slightly ground glass containers, and indicate the name of the manufacturer, product weight and product number on the label. Quantity and sample request date, one for inspection, the other for bottle and reserve:
6,4 If there is an indicator that does not meet the standard requirements during the acceptance, the company may "contract a new temporary inspection". If the inspection results still have indicators that do not meet the requirements, the batch of products cannot be accepted. 6.5 When both the supply and demand parties have objections to the product, the company will request the statutory inspection agency to make a decision: the cost is small.
For marking, packaging, transportation, purchase and storage||t t||71 The English shop can provide a certain degree of listening to the needle inside the car, the door has become a cross piece, and the outer juice is also installed: product name, manufacturer name, trademark, number, net year, leather, factory date, original quantity, order unit. If there are special requirements, you can reach an agreement with the manufacturer.
7.2 During delivery, you should prevent the mountains and rivers from raining and residual air from taking into account the rate of leakage, and you must not confuse the natural environment. The storage effect is in the network Beijing explosion place 7,3 Under the conditions of the specified transportation, the installation is complete, and the situation is not sealed, the warranty period of wooden products is one year. —
