AATCC TM165-1999e7(2013)e3, Colorfastness to Crocking: Textile Floor Coverings-Crockmeter Method
Developed in 1986 by AATCC Committee RA57; reaffirmed 1987, 1988; editorially revised and reaffirmed 1993, 2008 (with title change), 2013; revised 1999 (with title change); editorially revised 1996, 2011, 2002, 2004, 2009, 2010, 2011, 2016, 2019. Partially equivalent to ISO 105-X12.
1. Purpose and Scope
1.1 This test method is designed to determine the degree of color transfer from the surface of textile floor coverings to other surfaces by rubbing. The intent is to reproduce as nearly as possible true-to-life situations in all constructions whether dyed, printed or otherwise colored.
1.2 Test procedures employing white test cloths, both dry and wet with water, are given.
1.3 As the use surface of a textile floor covering may be exposed to various conditions in true-to-life situations, such as soils, stains, cleaning, shampooing and application of chemical treatments such as antisoils, antistats, antimicrobials, etc., the test may be made before, after, or before and after such situations.
2.1 A colored test specimen held on the base of a crockmeter is rubbed with a white test cloth under controlled conditions.
2.2 Color transferred to the white test cloth is rated by comparison with the AATCC 9-Step Chromatic Transference Scale or Gray Scale for Staining and a grade is assigned.
