This Standard specifies the methods for determination of fabric oil repellency with of a selected series of liquid hydrocarbons of different surface tensions.
This Standard is applicable to various textiles and their products.
This Standard is intended to provide a guide to oil stain resistance. It can provide a rough index of oil stain resistance as, generally, the higher the oil repellency grade, the better resistance to staining by oily materials, especially liquid oil substances. This is particularly true when comparing various finishes for a given substrate. This Standard can also be utilized in determining if washing and/or drycleaning treatments have any adverse effect on the oil repellency characteristics of a substrate.
Note: Washing and drycleaning treatment procedures are described in GB/T 8629 or GB/T 19981 (all parts), respectively.
This Standard is not intended to estimate the resistance to penetration of the substrate by oil-based chemicals.
