WARNING — Persons using this International Standard should be familiar with normal laboratory
practice. This standard does not purport to address all of the safety problems, if any, associated with
its use. It is the responsibility of the user to establish appropriate safety and health practices and to
ensure compliance with any national regulatory conditions.
CAUTION — Certain procedures specified in this International Standard may involve the use or
generation of substances, or the generation of waste, that could constitute a local environmental
hazard. Reference should be made to appropriate documentation on safe handling and disposal after use.
This International Standard specifies a method for the determination of the static adhesion of textile cord to
vulcanized rubber using the H-pull test. It is applicable to cords made from natural or man-made fibres.
The property levels obtained with this method are affected considerably by the history of the cord and the
rubber compound. The method yields data, however, on which a judgement as to the service quality of the
material can be based.
The method is primarily intended for use with tyre cord. However, it can be applied, if desired, to similar cords
for use in other rubber products, but it is limited to cords of linear density not exceeding 800 mg/m (tex).
