Rubber- or plastics-coated fabrics - Determination of tensile strength and elongation at break (ISO 1421:2016); German version EN ISO 1421:2016
Mit Kautschuk oder Kunststoff beschichtete Textilien - Bestimmung der Zugfestigkeit und der Bruchdehnung (ISO 1421:2016); Deutsche Fassung EN ISO 1421:2016
Overview
This International Standard specifies two methods for the determination of the tensile strength of fabrics coated with rubber or plastics: Method 1 - the strip test method, which is a method for the determination of tensile strength and elongation at break; Method 2 - the grab test method, which is a method for the determination of tensile strength only. The methods apply to test pieces in equilibrium with specific standard atmospheres for testing and to wet test pieces. Both methods require the use of a constant rate of extension (CRE) tensile-testing machine. The responsible German standardization committee is Working Committee NA 054-04-04 AA "Kunststoff-Folien und kunststoffbeschichtete Flächengebilde (Kunstleder); allgemeine Eigenschaften" ("Plastic films and plastics-coated fabrics (artificial leather); general characteristics") at DIN Standards Committee Plastics (FNK).
