This International Standard specifies a method for the determination of rubber-to-fabric adhesion under direct tension. It is only suitable when the matrial to be tested is substantially uniform in thickness and flat or sufficiently flexible to be maintained flat under light pressure. It is particularly suitable for materials having a very thin rubber layer which are difficult to test by stripping or peeling methods. However it should be noted that the results obtained by this method will not necessarily correlate with those obtained by a stripping test such as that described in ISO/R 36, Determination of the adhesion strength of vulcanized rubbers to textile fabrics.
