scope:

Specifies a method to measure the total thickness of both the backing and adhesive layer comprising an adhesive tape. The thickness is a useful factor in defining and adhesive tape and checking its uniformity. It is used in the determination of physical and electrical properties. Since the width of adhesive tape shall be greater than the diameter of the pressure foot on the micrometer, and as this can be up to 12 mm, the method is therefore not strictly applicable to adhesive tapes having a width less than the diameter of the foot. Nevertheless, this method can be applied to adhesive tapes of width less than the diameter of the circular foot on the micrometer. However, in this case, the value obtained can only be approximate.
