This document specifies a method for the assessment of the surface resistance to microscratching and relates to rigid surfaces of all finished products, considering the following exceptions: Method A is suitable for all types of surface coatings and coverings except for lacquers with pearly or metallic effects. Method B is suitable for all types of surface. No method applies to finishes on leather and fabrics. The test is intended to be carried out on a part of finished furniture, but can be carried out on test panels of the same material, finished in an identical manner to the finished product, and of a size sufficient to meet the requirements of the test. It is essential that the test is carried out on unused surfaces.
