This document specifies a test method for the determination of the relaxed elastic modulus of light conveyor belts according to ISO 21183-1 or other conveyor belts where ISO 9856 does not apply.
Abstract
Overview
ISO 21181:2025 specifies a test method for determining the relaxed elastic modulus of light conveyor belts (the “k 1% value”) used where does not apply, and for belts covered by . The standard describes sample preparation, conditioning, cyclic stretching, data collection and a logarithmic regression procedure to calculate the long-term (relaxed) tensile stiffness that reflects both elastic relaxation and any small permanent stretch.
