1 Scope
This part of GB/T 21196 specifies requirements for the Martindale testing apparatus and auxiliary materials for use in the test methods specified in parts 2 to 4 of GB/T 21196 for determination of the abrasion resistance of fabrics.
This part is applicable to apparatus for the testing of:
a) woven and knitted fabrics;
b) pile textiles having a pile height of up to 2 mm;
c) nonwovens;
d) Coated fabric: base cloth is woven or knitted fabric, and the coating form a continuous film on the fabric surface.
Note: The choice of method of abrasion testing is established before the start of the testing and recorded in the test report, since the results of the different methods cannot be compared with each other. The determination of resistance to pilling of fabrics using the Martindale apparatus is given in ISO 12945-2 Textiles — Determination of the resistance to pilling and change of appearance of fabrics — Part 2: Modified Martindale method).
