AATCC TM118, Test Method for Oil Repellency: Hydrocarbon Resistance

Developed in 1966 by AATCC Committee RA56; reaffirmed 1972, 1975, 1978, 1983, 1989, 2002, 2012; editorially revised 1985, 1986, 1990, 1995, 2004, 2008, 2010, 2016, 2019, 2021; revised 1992, 2007, 2013, 2020; editorially revised and reaffirmed 1997. Technically equivalent to ISO 14419.

1. Purpose and Scope

1.1 This test method is used to detect the presence of a fluorochemical finish, or other compounds capable of imparting a low energy surface, on all types of fabrics, by evaluating the fabric's resistance to wetting by a selected series of liquid hydrocarbons of different surface tensions.

2. Principle

2.1 Drops of standard test liquids, consisting of a selected series of hydrocarbons with varying surface tensions, are placed on the fabric surface and observed for wetting, wicking, and contact angle. The oil repellency grade is the highest numbered test liquid which does not wet the fabric surface.
