Adhesion Test

The adhesion test enables determination of ply adhesion between constitutive elements of items such as conveyor belts. The material specimen is prepared in accordance with EN ISO 252-1. At one end of the specimen (cut lengthways) the first layer is removed and clamped in the specimen grips. The document specifies two test methods A and B for determining the adhesive strength between the plies and between the covers and carcass of conveyor belts; the basic test conditions conform to ISO 36. The test is applicable to all types of conveyor belt, with the exception of belts with steel cord reinforcement and textile-reinforced belts with a full-thickness tensile strength of less than 160 N/mm.
