GB/T 8719-2022General rule for packing,marking,storage,transport and quality certificates of carbonaceous material and products (English PDF)

6.1 General

The packing of carbonaceous material and products shall meet the requirements of product protection, convenient transport, handling, and storage. For products transported in containers, the shipping packing shall match the size of the container. If the user has special requirements for packing materials and packing methods, it can be implemented according to the agreement between the supplier and the purchaser.

6.2 Packing requirements for graphite electrodes

6.2.1 Graphite electrodes shall be packed in wooden boxes, wooden slats and bottom brackets that meet the load-bearing requirements. The joint holes shall be protected using foam plastic covers or corrugated cardboard covers, and reinforced with steel straps. The contact surface between the steel strip and the electrode should be cushioned with buffer materials such as corrugated cardboard.

6.2.2 The packing of each component shall be symmetrical and uniform. The wooden components shall be connected in a staggered manner with steel nails. There shall be no missing nails, rising nails, and protruding nail caps and tips. The steel strip shall be tightly tied and shall not be loose.

6.2.3 The upper part of the bottom support shall have a block or wedge structure to prevent the electrode from rolling. The lower part of the bottom support shall have a The packing of graphite anode shall be carried out according to relevant standards.

6.8 Packing requirements for carburizers for steelmaking

6.8.1 According to the packing form, carburizers for steelmaking are divided into small packages and container bags.

6.8.2 In the form of small package, the product can be put into a plastic bag and sealed first; then put into a plastic woven bag or paper bag and sewed; or packed in a plastic woven bag lined with plastic film and then tightly sewed.

6.8.3 For products directly packed in container bags, the container bags shall be lined with plastic bags or lined with plastic film.

6.8.4 The packing process shall be done in a clean and dry environment.

6.9 Packing requirements for graphite-based negative electrode materials

6.9.1 According to the packing form, graphite-based negative electrode materials are divided into small packages and container bags.

6.9.2 In the form of small package, the product can be put into a plastic packing bag and sealed first; then packed into a corrugated carton (barrel).

6.9.3 For products directly packed in container bags, the container bags shall be lined with plastic bags or plastic film. The container bags should not be filled to the brim. It is recommended that each bag has a net weight of 500 kg.

6.9.4 The packing process shall be done in a clean and dry environment.

6.10 Packing requirements for activated carbon for supercapacitors

6.10.1 First put the product into a moisture-proof packing bag (it is recommended to use a plastic sealed bag, aluminum-plastic sealed bag); then vacuum-seal it; then pack it in a composite bag or plastic bucket, paper bucket, etc.

6.10.2 The packing environment shall meet the requirements of the product in terms of temperature, humidity and other conditions. It shall not affect the product quality.

6.11 Packing requirements for other carbonaceous materials and products

6.11.1 When packing the product, it shall be fixed. The fragile parts shall be packed with soft filler, to prevent loosening and damage during transport.

6.11.2 Bulk carbonaceous materials shall be packed in wooden boxes, iron boxes (drums) or plastic woven bags lined with plastic cloth. There shall be no leakage.

7.1 Product marking

7.1.1 Marking for graphite electrode products

7.1.1.1 The finished graphite electrode shall be marked with a safety line on the surface of the electrode corresponding to the bottom of the joint hole.

7.1.1.2 The safety line mark of the finished graphite electrode shall be uniform and clear.

There shall be no sticking phenomenon. There shall be no two or more safety line marks on the same end.

7.1.1.3 The bottom of the joint hole of the finished graphite electrode shall be affixed with a label. The label shall indicate the type, specification, bulk density, resistivity, weight, production date, etc.

7.1.2 Marking for finished carbon blocks

Finished carbon blocks shall be marked with materials that are not easy to fall off. The marks shall be clear and firm.

7.2 Package marking

7.2.1 The package shall, on the obvious part of the outer surface, be marked with the name of the manufacturer, product designation, model, specification, executed standard, grade, quantity, gross weight, and net weight, etc. Each product shall be accompanied by a certificate of conformity or a mark of conformity.

7.2.2 The transport marks and package marking methods shall be in accordance with the provisions of GB/T 191.

7.2.3 Dangerous goods transport marks and package marking methods shall be in accordance with the provisions of GB 190. […]
