家具 表面涂层试验 第6部分：抗划伤性能评估

[中文适用范围]： 本文件规定了两种评估表面抗不同种类可见划痕性能的方法。该标准适用于所有成品的刚性表面，无论其材质如何，但不适用于皮革和织物的表面处理。方法A适用于除三聚氰胺饰面板（依据EN 14322）和HPL（依据EN 438-1）以外的所有类型的表面涂层和覆盖层。该方法模拟可测量的穿透性和/或变形性划痕。方法B适用于所有类型的表面，模拟首次可见的痕迹（例如划痕、印记），也可能表现为光泽的变化。该测试应在一个已完成的家具部件上进行，但也可以在与成品材料相同、处理方式一致、尺寸足够满足测试要求的测试面板上进行。测试应在未使用、无任何缺陷或损坏的表面上进行。 [外文原描述]： This document specifies two methods for the assessment of surface resistance to different kinds of visible scratches. It is applicable to the rigid surfaces of all finished products, regardless of their material. It does not apply to finishes on leather and fabrics. Method A is suitable for all types of surface coatings and coverings except for melamine faced boards (in accordance with EN 14322) and HPL (in accordance with EN 438-1). It simulates measurable penetrating and/or deforming scratches. Method B is suitable for all types of surfaces. It simulates first visible traces (e.g. scratches, marks) that can also be a change in the gloss. The test is intended to be carried out on a part of finished furniture. It can, however, 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 carried out on unused surfaces without any defects or damages.
