Anotace

This document specifies three methods for the measurement of total belt thickness and the thickness of covers of steel cord conveyor belts.
Methods A1 and A2 (micrometer methods) can be used for all steel cord conveyor belts for the measurement of both total belt thickness and cover thickness.
Method B (optical method) is intended for the measurement of cover thickness only. It is not suitable if there is a textile or metal weft, nor if the ends of the steel cords become twisted when cut
