This Standard specifies methods of test for the full thickness breaking strength in the longitudinal direction and the elongation at the reference load in the longitudinal direction of conveyor belts having a textile carcass. It also specifies methods for the determination of breaking strength in the transverse direction and elongation at break in the longitudinal direction, for use when the manufacturer is requested by the purchaser to state values for these properties. This Standard is not suitable or valid for light conveyor belts as described in ISO 21183-1.
