ISO 1 2947-3: Textiles - Determination of Wear Resistance of Fabrics by the Martindale Method, Part 3: Determination of Quality Loss "is a textile wear resistance test standard published by the International Organization for Standardization (ISO). This standard specifies how to evaluate the wear resistance of fabrics through quality loss when testing the wear resistance of fabrics using the Martindale Method. The Martindale Method is a test method that simulates repeated friction of fabrics in actual use. The wear resistance of fabrics is quantitatively assessed by measuring the amount of quality reduction after a specific number of rubs. This standard applies to all types of fabrics and provides a scientific basis for the quality control and performance evaluation of textiles.
