<p>ISO 1421:2016 specifies two methods for the determination of the tensile strength of fabrics coated with rubber or plastics.</p>
<p>- Method 1 ? the strip test method, which is a method for the determination of tensile strength and elongation at break.</p>
<p>- Method 2 ? the grab test method, which is a method for the determination of tensile strength only.</p>
<p>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.</p>
