Machine-made textile floor coverings. Determination of dimensional changes after exposure to heat and/or water
1 Scope This International Standard 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.
