GB/T 3686-2014 Belt drives - V-belts and V-ribbed belts - Tensile strength and elongation test method
1 Scope
This standard specifies the test methods for tensile strength, elongation at the reference force and elongation at break of V-belts and V-ribbed belts.
It is applicable to the determination of tensile strength and elongation of various driving V-belts and V-ribbed belts under specified conditions.
