BS ISO 36:2020 pdf download.Rubber, vulcanized or thermoplastic — Determination of adhesion to textile fabrics
1 Scope
This document specifies a method of test for measuring the force required to separate, by stripping, two plies of fabric bonded with rubber, or a rubber layer and a fabric ply bonded together. The method is applicable when the ply surfaces are approximately plane or when they are in the form of a cylinder having an internal diameter greater than approximately 50 mm. The method is not applicable when the ply surfaces contain sharp bends, angles or other gross irregularities which cannot be excluded when cutting out test pieces. This document does not apply to coated fabrics, which are tested in accordance with ISO 2411, or textile conveyor belts, which are tested in accordance with ISO 252.

3.1 adhesion strength
force per unit width required to cause a separation at the interface between the assembled components
Note 1 to entry: Any separation occurring at any other point, for example inside either component under test,is a failure of the component material, and does not indicate an adhesion strength. In such cases, the adhesion strength is greater than the strength of the weakest component involved.
7.2 Test piece prepared in laboratory
Test pieces with dimensions as described in 7.1 shall be prepared masking one end for a distance of approximately 50 mm with pressure sensitive tape or a plastic film, in order to leave the edge of the test sample adhesion free, so that the separated ends can be fixed/attached to the test machine grips (see Figure 2).
