符合该欧洲标准的层压板被称为外部级紧凑型层压板，其特点是具有高抗拉强度、高抗冲击性、抗热震性以及耐候性和耐腐蚀性。它们有多种装饰颜色可供选择，在户外应用中具有很高的耐变色和耐老化性。当它们是自支撑的时，外部级紧凑型层压板已准备好安装，只需要切割尺寸、钻孔等以适应应用。EN 438-2 规定了与 EN 438 的这一部分相关的测试方法。 一、标准名称： EN 438-6:2005 High-pressure decorative laminates (HPL)-Sheets based on thermosetting resins (usually called Laminates)- Part 6: Classification and specifications for Exterior-grade Compact laminates of thickness 2 mm and greater EN 438-6:2005 装饰用高压层压制件(HPL).热固性树脂为基质的板材.*6部分:等于和大于2mm厚的外部用压实层压板材的分类和规范
