Ordinary conveyor belts shall comply with the GB7984-2001 standard.

Ordinary conveyor belt: covering layer: tensile strength not less than 15Mpa, elongation at break not less than 350%, wear Less than or equal to 200mm3; average value of interlayer adhesion strength longitudinal sample between layers not less than 3.2N/mm; covering adhesive and cloth layer not less than 2.1N/mm; longitudinal elongation at break not less than 10% for full thickness; longitudinal reference force elongation not more than 1.5% for full thickness.

Nylon (NN) and polyester (EP) conveyor belt cover layer, with tensile strength not less than 15Mpa and elongation at break not less than 350%. The average value of interlayer adhesion strength of longitudinal specimens between layers is not less than 4.5N/mm, and the thickness of the covering adhesive is not less than 3.2N/mm. The longitudinal elongation at break is not less than 10%, and the longitudinal reference elongation at full thickness is not more than 4%. The covering adhesive is made of rubber plastic blend, and the skeleton has a national standard tensile strength coefficient, which can be overlapped into a circular shape.
