标准摘要
[中文适用范围]： 本文件规定了根据涂料或产品规范的要求测定漆膜、涂料体系和相关产品耐冷凝条件的方法。 该方法适用于木材、石膏和石膏板等多孔基材上以及金属等非多孔基材上的涂层。 它表明了在表面发生连续凝结的恶劣暴露条件下可能获得的性能。 该程序可以揭示涂层的故障（包括起泡、染色、软化、起皱和脆化）和基材的劣化。 注：本文件不包括试验样品的形状和制备、试验持续时间以及试验结果的评估。 [外文原描述]： ISO 6270-1:2017 specifies a method for determining the resistance of paint films, paint systems and related products to conditions of condensation in accordance with the requirements of coating or product specifications. The method is applicable to coatings, both on porous substrates such as wood, plaster and plasterboard and on non-porous substrates such as metal. It provides an indication of the performance likely to be obtained under severe conditions of exposure where continuous condensation occurs on the surface. The procedure can reveal failures of the coating (including blistering, staining, softening, wrinkling and embrittlement) and deterioration of the substrate. NOTE The shape and preparation of the test specimens, the duration of the test and the assessment of the test results are not covered by this document.
