This document specifies a method for the assessment of the abrasion resistance of surfaces with foils, laminates, melamine faced boards, pigmented and transparent lacquers. It does not apply to leather and textile surfaces. It does not apply to the surfaces covered by EN 14434. The test is intended to be carried out on an unused part of the 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. The test is intended to be carried out on unused surfaces.<\/p>\n
