AATCC Test Method 116-2005

Colorfastness to Crocking:  Rotary Vertical

Crockmeter Method

Developed in 1966 by AATCC Committee RA38

1.  Purpose and Scope

1.1  This test method is used to determine the amount of color transferred from the surface of colored textile materials to other surfaces by rubbing.  It is applicable to textiles made from all fibers in the form of yarn or fabric, whether dyed, printed or otherwise colored and especially to prints where the singling out of areas smaller than possible to test with the standard AATCC Crockmeter (AATCC Test Method 8) is required.
1.2  Test procedures employing test squares either dry or wet with water or other liquids are within the scope of this method.

2.  Principle

2.1  A test specimen held at the base of the Rotary Vertical Crockmeter is rubbed with standard test squares under controlled conditions.
2.2  Color transferred to the test squares is assessed by comparison with the Gray Scale for Staining or AATCC Chromatic Transference Scale.
