EN ISO 1421 Rubber or Plastic Coated Fabrics, Determination of Tensile Strength and Elongation at Break

EUROLAB laboratory provides testing and compliance services within the scope of EN ISO 1421 standard. ISO 1421 specifies two methods for determining the tensile strength of rubber or plastic coated fabrics.

Method 1: Strip test method, which is a method for determining tensile strength and elongation at break.
Method 2: Grip test method, which is a method for determining tensile strength only.

The methods are applied to test pieces and wet test pieces that are in equilibrium with certain standard atmospheres for testing. Both methods require the use of a constant elongation rate (CRE) tensile testing machine.

A test piece is extended at a constant rate of extension until it breaks. For method 1, the maximum force and elongation at maximum force and, if necessary, the force at break and elongation at break are determined. For method 2, only the maximum force is determined.

Cut two sets of test pieces from each sample, one in the longitudinal direction and one in the transverse direction. Each set should consist of at least five test pieces. Test more test pieces if a higher degree of certainty is required by agreement between the parties involved.
