Scope

Single Test Cord8212; Adhesive treating of cords singly or adhesive treating individual ends simultaneously (referred to as “multi-cord treating” as opposed to “fabric treating”) and winding the cords as single ends is the most common laboratory method of preparing reinforcement materials for evaluation in reinforced rubber articles such as tires, belts, and hoses. This system of adhesive treating facilitates the study of a large number of adhesion variables at minimum cost. This test method provides a good comparison of variables on adhesion because it produces both an average numerical value of peel force over several linear centimetres of cord and provides convenient specimens for assessing appearance (see 11.3) of the peeled area as well. It may be used for purchase specification requirements for adhesive treated cords, steel tire cord, adhesives, rubber compounds, or manufacturing control of such products.

Preparation of weftless fabric from single cord is not recommended for acceptance testing of commercial shipments of tire cord fabric because single cords of long length cannot be conveniently obtained from fabric for drumwinding. See 5.2.2.

This test method is usually not preferred for acceptance testing of commercial shipments of adhesive treated cord, such as single end cord for hose. The more usual and convenient method for acceptance testing of such single cords is to prepare from a shipment a test piece or article in the same manner as the commercial article to be produced and to test cord-adhesion characteristics in this piece in a manner that compares its adhesion characteristics against a previously established, acceptable control. “H” and“ U” tests (Test Methods ) provide convenient and rapid adhesion results for acceptance testing of textile cords if needed. For steel cord, Test Method D2229 provides convenient and rapid adhesion results.

Using Woven Fabric8212;The woven fabric method of 4.2-4.4 is often chosen for rapid adhesion testing of textile woven fabric being adhesive treated in large volume. Fabric is tested “as is” and, through experience, constitutes a valuable process control tool. The same basic test can be conveniently executed by the receiving customer for process control purposes by sampling rubberized fabric from that to be processed into finished rubber articles.

This test method may be used for acceptance testing of commercial shipments of adhesive treated fabric, but duplicate numerical values for peel force and appearance are not to be expected between two testing locations. Rubber compound differences are only one of many parameters affecting peel force and appearance. Nevertheless, the expected range of values which characterize acceptable adhesion can be determined in any cord-rubber combination with experience. For this reason, the buyer normally establishes a minimum level of adhesion to be obtained by the seller in the seller's laboratory using either the seller's standard rubber compound or the buyer's rubber compound on the fabric made to the buyer's specification.

In case of a dispute arising from differences in reported test results when using Test Method D4393 for acceptance testing of commercial ship......
