This Publicly Available Specification specifies procedures for the determination of both planar and out-of-plane dimensional changes that take place when machine-made textile floor coverings are subjected to heat, water or varied heat and water conditions. The following methods are applicable to all machine-made textile floor coverings including those produced in tile form. — Method 1: Determination of dimensional changes after exposure to heat. — Method 2: Determination of dimensional changes after immersion in water. — Method 3: Determination of dimensional changes due to the effects of varied heat and water conditions. — Method 4: Dimensional changes out of the plane.
