ASTM D4776-98

1.1 This test method covers the measurement of adhesion of reinforcing cords that are bonded to rubber compounds. This test method is applicable to textile cord structures from both natural and manmade fibers, other than steel. For adhesion testing of steel tire cords, refer to Test Method D 2229.

1.2 This test method is primarily used to evaluate tire cords, using a suitable tire cord adhesive and a suitable rubber compound. This test method is also used to evaluate (1) tire cord adhesives, and (2) the process of adhesive reaction on the cord using one consistent form of tire cord and one consistent rubber compound. This test method may be used to evaluate cords in industrial hose and belting products and other cord reinforced rubber products.

1.3 This test method is written in SI units. The inch-pound units which are provided in this test method are not necessarily exact equivalents of the SI units. Either system may be used in this test method.

1.4 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
