1 Scope
This document specifies a test method for determining the transverse flexibility (troughability)
of a conveyor belt, expressed as a ratio, F / L . The method is not suitable or valid for light conveyor belts as described in ISO 21183‑1 .
NOTE The transverse “flexibility” determined by the method described in this document is
only indirectly associated with the inverse of flexural modulus as specified in ISO 178 . Nor does it take into consideration the differences in “flexibility” as exhibited
by three-point and four-point bending, which takes account of the flexural strain
and the thickness of the test piece.
