GB/T 11416—2002
6.2.3 For each batch of inspection, all the above items must be qualified. If one item is unqualified, it should be sorted out by the production department and re-inspected. If the products re-submitted for inspection still do not meet the requirements, the batch will be considered unqualified.7 Marking, packaging, transportation, storage
7.1 Marking
7.1.1 Each product or its packaging should have a clear mark indicating the product's name, capacity, manufacturer's name and address, trademark and quality grade, etc., and should be accompanied by a product manual and certificate of conformity. 7.1.2 The instructions shall state the product name, capacity, caliber, manufacturer name and address, telephone number, quality grade, standard number, quality assurance, exchange requirements and other terms that need to be explained; and state the method of use and precautions during use. 7.1.3 The transport package shall indicate the manufacturer name, product number, grade, quantity, package box size, volume, quality, packing date and receipt mark. 7.1.4 The package box shall have signs such as fragile, moisture-proof and not allowed to be inverted. The signs shall comply with the provisions of GB/T6388. 7.2 Packaging
7.2.1 Packaging is divided into sales packaging and transport packaging. 7.2.2 The thermal insulation container shall be wrapped with moisture-proof packaging such as plastic film before being placed in the sales packaging box. 7.2.3 The transport packaging shall use a single corrugated box or double corrugated box that meets the requirements of GB/T6543. 7.2.4 When packing finished products, the bottom of the bottle should be placed straight down. When sealing the box, the bottom and the lid of the box should be sealed and glued with adhesive. When bundling, the bundling belt should be moderately tight.
7.3 Transportation
7.3.1 During transportation, moisture, rain and severe vibration should be avoided. 7.3.2 During transportation, the products should be handled and placed with care, not inverted, not sat on or stepped on at will, and throwing is strictly prohibited. 7.4 Storage
7.4.1 The storage area should be dry, ventilated, and free of rain and snow. Prevent moisture. 7.4.2 During storage, the stacking height should not exceed 3.5m, and it should be avoided from mixing with oils, acids and alkalis during storage. A1 Scope of application
