scope:

NEN-ISO 17984 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.
