本文件规定了三种测量钢绳芯输送带总厚度和盖板厚度的方法。 方法A1和A2（千分尺法）可用于所有钢丝绳芯输送带，以测量皮带总厚度和盖板厚度。 方法B（光学法）仅用于测量覆盖层厚度。如果有织物或金属纬线，或者钢丝绳的末端在切割时扭曲，则不适用。

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.
