4.3 Quality requirements for soft awnings 4.3.1 Materials and appearance Soft awnings should be made of thick canvas or rubberized cloth. Plastic-coated cloth can also be used. It should have sufficient strength, be wear-resistant, durable, and not stretchable. The coating should be of uniform thickness and color. There should be no defects such as missing coating, lumps, holes, degumming, wrinkling and damage. The hemming should be straight, without problems such as loose needles, broken threads, and floating threads. 4.3.2 Quality Water-proof performance should comply with HG/T2582 standard, low temperature resistance should comply with FZ/T01007 standard, and flame retardancy should comply with XF/T91 flame-retardant awning cloth standard requirements. 4.3.3 Sewing and splicing If the awning is made of several pieces, the edges of the pieces should be folded over each other and sewn with two seams with a minimum spacing of not less than 15 mm. When some parts of the awning (such as the flaps and reinforced corners) cannot be spliced in the above manner, the edges of the top section can be folded and sewn. One of the seams shall be visible only from the back and shall be of a thread colour which is clearly different from that of the tarpaulin and the other seam. All seams shall be machine stitched. 4.3.4 Fusion stitching If the tarpaulin is plastic coated and is made of several panels, the panels shall overlap by at least 15 mm and the entire width of the overlap shall be fused. A plastic strip shall be attached to the edge of the outer tarpaulin using the same welding method, the width of which shall not be less than 7 mm. A uniform pattern shall be embossed on the plastic strip and on both sides for at least 3 mm. The panels shall be fused so that they cannot be disassembled and reconnected without leaving obvious traces. 4.3.4.1 Fusion of plastic strips The provisions for plastic strips are key to achieving customs control safeguards. 4.3.5 The overlap width of the tarpaulin panels shall be 20 mm or even wider, depending on the material of the tarpaulin and its adhesive strength. 4.3.6 The repaired edges shall overlap each other and be sewn with two visible seams at least 15 mm apart; the color of the seams visible from the back shall be different from the color of the seams on the front and the color of the tarpaulin itself; all seams shall be sewn by machine. 4.4 Welding requirements 4.4.1 The welding rods, welding wires and flux used for welding shall comply with the provisions of GB/T5117 and shall match the materials of the welded structural parts. 4.4.2 The weld groove form shall comply with the provisions of GB/T985.1. 4.4.3 The quality of the butt weld of the load-bearing structural parts shall not be lower than Grade I specified in GB/T11345. 4.4.4 The welded joints and weld dimensions of the components shall comply with the provisions of GB/T25776. All welds shall not have defects such as leaks, burn-throughs, cracks, incomplete penetration, weld nodules, undercuts, slag inclusions, etc. that affect the performance and appearance quality. 4.5 Requirements for Sealing of Cargo Boxes4.5.1 Cargo Box Structure4.5.1.1 The cargo box structure must comply with the relevant requirements of the Customs Convention on the International Carriage of Goods under the TIR Carnet, and must be tight and complete. Customs seals must be applied to the sealed parts of the cargo compartment. If goods are taken out or loaded by illegal means, the customs seals will be damaged or traces of unpacking will be left outside the cargo compartment. There should be no hidden parts in the cargo compartment for hiding goods. 4.5.1.2 The cargo space in the cargo compartment should be convenient for vehicle verification and customs inspection. 4.5.1.3 Doors and other closing devices4.5.1.3.1 Doors and other closing devices should be equipped with devices that can easily and effectively apply customs seals. Their structural design should ensure that the doors and all other closing devices cannot be opened from the outside of the cargo compartment, otherwise the customs seals will be damaged. 4.5.1.3.2 Devices that can apply customs seals must be fixed by welding, or designed so that the device cannot be removed without leaving obvious traces after closing and sealing. 4.5.1.3.3 The device capable of applying the customs seal must contain a circular hole with a diameter greater than or equal to 11 mm or a rectangular hole with a length and width of at least 11 x 3 mm and have the same control reliability regardless of the seal used. 4.5.1.3.4 The butt hinges, slat hinges, hinge nails or other devices used to secure the door must ensure that once the door is closed and the customs seal is applied, it cannot be replaced without leaving obvious traces. 4.6 Tarpaulin fastening and sealing 4.6.1 Tarpaulins may be fastened by the following means: 4.6.1.1 Metal rings fixed to the vehicle 4.6.1.2 Grommets on the edges of the tarpaulin 4.6.1.3 Tie ropes that pass through all loops protruding from the tarpaulin's grommets and whose full length is visible from the outside. 4.6.2 When any side of the tarpaulin is to be permanently fixed to the vehicle, the two contacting surfaces must be joined together without leaving any gaps and fastened by a solid device. 4.6.3 When a tarpaulin locking system is used, it should be such that in the locked position the tarpaulin is tightly fixed to the outer wall of the load compartment. 4.6.4 The tarpaulin should be adequately fastened to the reinforcing structure (vertical columns, side panels, arches, beams, etc.). 4.6.5 The spacing between the rings and the eyelets should not exceed 200 mm. 4.6.6 The following fastening devices should be used: 4.6.6.1 Steel wire rope with a diameter of not less than 3 mm; 4.6.6.2 Spiral steel cable with optical fiber bundle inside, covered with a transparent sheath made of non-stretchable plastic; 4.6.7 All types of ropes must be whole and have hard metal ferrules at both ends. The metal ferrules should be perforated to allow the passage of customs sealing wire or tape. On the fastening buckle of each metal ferrule, there should be a hollow rivet that passes through the rope to allow the passage of customs sealing wire or tape. The rope should still be visible on both sides of the banjo rivet so that it can be confirmed that the rope is a single piece.
