1 Scope
This European Standard specifies a static test method for measuring the strength of a conveyor belt mechanical fastening; the mechanical joints can be either of the type employing a connecting rod or of a type which does not employ a connecting rod.
This standard does not cover vulcanized joints.
NOTE The purpose of the test specified in this standard is to eliminate mechanical fastenings of insufficient static strength. A dynamic test will be established at a later date.
The standard is not applicable or valid for light conveyor belts as described in EN 873.

This EN specifies two methods of measuring the total thickness and the cover thickness of steel cord conveyor belts. Method A, (Micrometer method) can be used for all steel cord conveyor belts for measurement of both total thickness and cover thickness. Method B (Optical method) is recommanded for the measurement of cover thicknesses only. It is not suitable if there is a textile or metal weft, or if the ends of the steel cords become twisted when cut.

This Standard describes a method of test for determining the full thickness tensile strength, elongation at break and elongation at the reference load of conveyor belts having a textile construction. Methods are in development for tensile strenghts greater than 2500 N/mm. This standard is not suitable or valid f for light conveyor belts as described in EN 873.

This European Standard describes four methods for the measurement of thickness of conveyor belts having a textile carcass. Method A describes a method for the determination of total belt thickness. Method B describes a method for the determination of thickness of covers. Method C describes a method for the determination of thickness of carcass. Method D describes a method for the determination of the thickness of the interlayers.
