Conveyor Belt Testing

The total belt elongation consists of an elastic (which recovers) and a plastic (which remains) portion. As per ISO 9856, a belt sample is subjected to a sinusoidal cyclic stress that varies from 2 to 10 % of the belt's nominal breaking strength. 2 - 10 %, because this is a typical operating range for textile conveyor belts.
