AATCC TM171-2019, Carpets: Cleaning of; Hot Water Extraction Method
Developed in 1987 by AATCC Committee RA57; reaffirmed 1988, 1989, 2000, 2005, 2014; editorially revised 1991,1997, 2008; revised 1995 (with title change), 2019; editorially revised and reaffirmed 2010.
Over the years, Committee RA57, Floor Covering Test Methods, has evaluated various techniques for on-site cleaning of carpets as they have emerged. Information exchanged with professional carpet cleaning organizations led to the selection of the system described in this test method as typical of a majority of actual cleaning operations.
1. Purpose and Scope
1.1 This test method provides a laboratory procedure to clean textile floor coverings by a technique simulating cleaning of installed floor coverings by hot water extraction, sometimes erroneously called "steam cleaning."
1.2 This test method may be used to clean a carpet in a manner that duplicates the most popular (70%) means of actual on-floor cleaning of carpets.
1.3 This test method prepares specimens that can be tested for many properties; e.g., colorfastness, dimensional stability, permanency of finishes, ease of cleaning, etc.
2.1 The test is performed by securing a specimen of carpet, face up, on floor or a mounting board. An extraction cleaning head is passed over each section of the specimen. The pile is erected with a brush or pile rake and the specimen is dried at room temperature.
