This Standard specifies the marking, technical requirements, inspection, marks, packaging, storage and transportation for flame retardant conveyor belts of textile construction for general use with rubber coverings (hereinafter referred to as belts). This Standard applies to flame retardant conveyor belts of textile construction for general use used in chemical, coal, metallurgy and electric power industries. This Standard applies to flame retardant conveyor belts of textile construction for general use with a working environment temperature of -20°C~45°C. This Standard does not apply to flame retardant conveyor belts used in coal mines. It is also inapplicable to flame retardant conveyor belts with metal skeletons.2 Normative references

3.1 Belt marking according to the following conveyor belt properties a) Refer to this Standard, namely GB/T 10822; b) Required length, in meters (m); c) Required width, in millimeters (mm); d) Fiber type of core warp and weft, for example, polyester (E) (warp) nylon (P) (weft), (EP); e) Through-thickness tensile strength, in Newtons per millimeter (N/mm) (see Table 3); f) Number of layers or type of conveyor belt; g) Thickness of the upper covering layer, in millimeters (mm); h) Thickness of the lower covering layer, in millimeters (mm); For conveyor belts made of synthetic fiber fabrics, type B specimens shall be used. For conveyor belts containing natural fiber fabrics as belt cores, type C specimens shall be used. 5.9 The interlayer adhesive strength of the belt shall be tested according to the provisions of Method A in GB/T 6759-2013. 5.10 The combustion performance of the belt shall be tested according to the provisions of GB/T 3685. 5.11 The electrostatic conductivity of the belt shall be tested according to the provisions of GB/T 3684. 5.12 The troughability of the belt shall be tested according to the provisions of GB/T 7983. 5.13 Belt straightness measurement: Unfold the belt on a flat surface. Straighten a 7m long wire along any part of the belt edge, so that the ends of the wire are on the edge of the belt. The maximum vertical distance from the measured belt edge to the straight line is the straightness. Pull a 5m-long wire with a belt width not greater than 500mm or a belt length not greater than 20m.6 Inspection rules
6.1 Inspection items 6.1.1 During the exit-factory inspection, the length, width, total thickness, entire thickness tensile strength and elongation of the belt, physical properties of the covering layer (excluding aging properties), interlayer bonding strength, straightness and safety performance shall be inspected. 6.1.2 Type inspection shall not be less than once a year during normal production. When major changes occur, type inspection shall be carried out. Inspect all technical requirements specified in Chapter 4 (except 4.10). 6.2 Sampling The sampling quantity is shown in Table 9. The length of each sample is not less than 450mm. The width is the full width of the belt. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
