GB/T 18946-2003 stipulates that the direct tensile method is used to determine the adhesive strength of rubber and fabric in rubber-coated fabrics. The standard specifies the required test equipment and sets requirements for the accuracy and range of the Tensile machine. Detailed sample prepative method, covering the size, shape and number of specimens. During the test, the sample is clamped on a tensile machine, and the tensile force is applied at a specified rate until the rubber and fabric are separated, the maximum tensile force value is recorded and the adhesive strength is calculated. The standard provides a unified method for the production and mass inspection of rubber-coated fabrics, helping enterprises control the mass of products and promote the standardization of the industry.
