This document gives test methods to determine the dimensional variance between elements of laminate floor coverings in a manufactured free-standing shape (unrestricted) in respect of thickness, length, width, squareness, straightness, width flatness, length flatness, openings between assembled elements and height differences between assembled elements.
NOTE    These test methods are also applicable to other mechanically assembled panels, e.g. modular multilayer floorings.
