This Standard specifies a method for the determination of the thickness loss of textile floor coverings under dynamic loading. It is applicable to all types of textile floor coverings with a surface that is level in height and construction. It does not apply to other textile floor coverings unless the areas of different thickness or construction can be tested separately.

This Standard describes a method for determining the strength of the bond between the backing components of a textile floor covering which can be peeled apart. This method is applicable to tufted carpets which have primary and secondary backing materials forming a bonded composite substrate.
