6.1 Product Placement and Packaging

The requirements for the placement and packaging of the product are as follows:

a) When placing the product, the center of gravity should be centered and lowered as much as possible to increase the stability. Products with a high center of gravity shall be horizontally placed. For products whose center of gravity significantly deviates from the center, corresponding balancing measures shall be taken;

b) The product or the inner packaging box shall be firmly padded and fixed inside the outer packaging box. In the packaging box, the product shall not be shifted or loose. The modes of fixation include: plugging with shock-proof materials, positioning and fastening with wooden blocks, and tightening with screws, etc.

The shock-proof cushion and the bottom board of the box shall not be less than 10 mm. If necessary, in accordance with the stipulations of GB/T 8166,

a) When corrugated box is used for the outer packaging, apply moisture-proof coatings, for example, varnish and white wax on the outer surface of the box (except for paper sheets that have received moisture-proof treatment and wood pulp-holding kraft paper sheets). In accordance with the product characteristics, select moisture-proof padding in the box. During sealing, use pressure-sensitive tapes or sturdy kraft papers to seal the joints of the upper and lower openings and the joints at both ends;

b) When a wooden box is used for the outer packaging, and the inner packaging has no moisture-proof packaging, the inner top shall be sealed with linoleum, asphalt paper, wax paper or equivalent moisture-proof materials;

c) The selection, dosage and disposal of moisture-proof materials and desiccants in the packaging shall be considered in accordance with the product characteristics, storage and transportation conditions, and the requirements for packaging modes and packaging validity period, and comply with the relevant stipulations of Appendix A in GB/T 5048-2017;

d) For the coated products, when covered or wrapped with polyvinyl chloride plastic films, measures shall be taken to prevent them from coming into direct contact with the paint layer;

e) When the outer packaging does not have moisture-proof measures, or the wood chips and paper chips are not dried, the wood chips and paper chips cannot be used as the padding of the product.

7.2 Anti-rust Requirements

7.2.1 The easily rusty metal surface on the product shall be packaged in accordance with Grade-2 in GB/T 4879-2016. When the anti-rust period is 1 year, the dirt and oil stains shall be removed, then, be cleaned, sealed and packaged.

H---the maximum storage height allowed in storage, expressed in (cm), which shall h; carry out the test under this condition. If it cannot be carried out under this condition, the specimen may be taken out and tested within 5 min. Use tape to seal the upper cover and lower bottom of the box being tested. Then, place it flat between the two pressing plates of the testing machine, so that the center line of the specimen coincides with the center vertical line of the two pressing plates of the testing machine. The test speed is (10 ± 2) mm/min. Record the pressure value, accurate to 1 N.
