Textiles - Test methods for nonwovens - Part 3: Determination of tensile strength and elongation
Application of a force longitudinally to a test piece of a specified length and width at a constant rate of extension. Determination of values for breaking strength and elongation from the recorded force-elongation curve. In order to meet the specific needs of nonwovens, alternative requirements to those listed in ISO 5081 are established in this part of ISO 9073. These are: a) a different sampling procedure b) a constant rate of extension (100 mm/ min).
