When necessary, temperature performance shall be considered. 5.2.1.2 Care shall be taken to avoid damage caused by battery effect caused by different metals in parallel. 5.2.2 Specific requirements for large packages made of soft materials 5.2.2.1 Large packages shall be made of suitable materials. The strength of the material and the structure of the soft large package shall be adapted to its capacity and purpose. 5.2.2.2 All materials used in the manufacture of 51M type soft packaging shall retain at least 85% of the tensile strength obtained when the material is in a relatively stable state at a relative temperature of 67% or less after being soaked in water for not less than 24 hours. 5.2.2.3 Seams shall be sewn, heat-sealed, bonded or other equivalent methods: all seam ends shall be tightly closed. 5.2.2.4 Soft packaging shall have sufficient resistance to degradation and strength loss caused by ultraviolet radiation, climatic conditions or extracted substances to prevent damage to the packaging.
5.2.2.5 Plastic packaging for protection against ultraviolet radiation shall be added with carbon, or contain suitable pigments or inhibitors. These additives shall be compatible with the substances contained and remain effective throughout the packaging. If the carbon black pigment or inhibitor used is different from that used in the manufacture of the tested equipment model, and the change in carbon black content, pigment content or inhibitor content will not have a significant effect on the physical properties of the manufacturing material, then new testing may be exempted. 5.2.2.6 As long as the additive does not damage the physical and chemical properties of the bulk packaging material, it may be mixed with the additive to enhance its anti-aging ability or play other roles. 5.2.2.7 When fully filled, the ratio of height to width shall not exceed 2:1. 5.2.3 Physical requirements for plastic bulk packaging
5.2.3.1 Bulk packaging should be made of a known specification of strict plastic material and have sufficient strength to adapt to its specific use. The material shall have adequate resistance to ageing and to the reduction in strength due to ultraviolet radiation of the contained material (if any), due consideration shall be given to low temperature performance, and any lacquer penetration of the contained material shall not constitute a hazard under normal operating conditions. 5.2.3.2 If protection against ultraviolet radiation is required, additives or other synthetic inhibitors or inhibitors shall be added. These additives shall be compatible with the contained material and remain effective throughout the shelf life of the bulk packaging: carbon black, pigments, glass inhibitors used in the manufacture of the tested equipment model shall be different from those used in the tested equipment model, and the change in carbon black content, pigment content, and inhibitor content shall not have an adverse effect on the physical properties of the manufactured material, and retesting may be exempted.
5.2.3.3 Additives may be added to the bulk packaging to enhance the ageing performance or to serve other purposes, but such substances shall not have an adverse effect on the physical or chemical properties of the material. 5.2.4 Specific requirements for fiberboard packaging -
5.2.4.1 High-quality solid or double-sided fiberboard (single or multi-layer) suitable for the capacity and frequency of the large package should be used. The water resistance of the outer surface should reach: the weight increase measured in the 3D-min test using the specified heat-resistant fabric method should not exceed 155 g/m (see G3/T1540). The fiberboard should have appropriate bending properties. The fiberboard should not have cracks or grooves when cutting or bending, so that it will not be torn, surface broken or deformed during assembly. The edges of the corrugated fiberboard should be firmly glued to the surface layer. 5.2.4.2 The four walls of the container, including the top and bottom plates, should have a minimum perforation resistance of 15" as specified in G3/T2679. 5.2.4.3 The seams of the outer containers of large packagings shall be made with appropriate attention to detail. They shall be glued, glued, sewn with metal staples, or secured with other means of at least equal effectiveness. If the seams are glued, water-resistant adhesives shall be used: metal staples shall pass completely through all parts to which they are to be fastened and shall be shaped or protected so that the lining of the packaging is not damaged or punctured by the staples. 5.2.4.4 Any integral pallet bottom forming part of the large packaging or any removable pallet shall be suitable for mechanical loading and unloading to the maximum permitted size of the large packaging.
5.2.4.5 The design of the pallet or integral pallet bottom shall avoid any protrusions on the bottom of the large packaging that may be easily damaged during loading. 5.2.4.6 The container shall be secured to any removable pallet to ensure stability during loading and transportation. When using removable pallets, the top surface of the pallet should be free of sharp protrusions that could damage the bulk packaging. 4
SN/T 1936.1--2007
5.2.4.7 Reinforcement devices, such as wooden supports, may be used to enhance stacking performance, but such devices should not be installed outside the lining sheet. 5.2.4.8 For bulk packaging intended to be stacked, the supports should be able to distribute the load safely. 5.2.5 Specific requirements for wooden bulk packaging 5.2.5.1 The strength of the material used and the method of support should be compatible with the nature and purpose of the bulk packaging. 5.2.5.2 Natural wood shall be thoroughly spray dried to commercial standards and free from defects which would substantially reduce the strength of any part of the package. Each component of the package shall be one piece or equivalent. Components may be considered equivalent if they are assembled by suitable methods of gluing, such as lind joints, tongue and groove joints, lap joints or tongue and groove joints, or butt joints with at least two metal staples at each joint or other methods at least as effective. 5.2.5.3 Plywood packages shall be at least three-ply sheets. They shall be thoroughly spun, sliced or sawn, dried to commercial standards and free from defects which would substantially reduce the strength of the package. All plies shall be bonded with a water-resistant adhesive. Other suitable materials may be used in conjunction with plywood to make packages. 5.2.5.4 Recycled technology packages shall be made of recycled wood residues of the type required by us, such as fiberboard, particleboard or other suitable types of material. 5.2.5.5 The packaging shall be securely pinned or clamped at the corner posts or ends, or assembled by suitable means. 5.2.5.6 Any integral pallet base or removable pallet forming part of the bulk packaging shall be suitable for mechanical loading and unloading of the bulk packaging.
