色漆和清漆.抗凹陷性评定

[中文适用范围]： 本国际标准描述了评估油漆、清漆和类似涂料（涂层）在施用于基材并保持垂直位置时的抗流挂性（抗流挂性）的测试方法。 抗流挂性的评估可以在涂层施涂后进行，如下：a) 在水平放置的测试板上使用流挂指数涂抹器，然后将其置于垂直位置，或 b) 使用喷枪在处于垂直位置的基板。 注：如果涂层均匀，也可以使用刷涂或滚筒涂敷。 本国际标准仅适用于液体涂料。 [外文原描述]： ISO 16862:2003 describes test methods for evaluating the sag resistance (resistance to sagging) of paints, varnishes and similar coating materials (coatings) when applied to a substrate and held in a vertical position. Evaluation of the sag resistance can be carried out after the coating has been applied as follows: using a sag index applicator on a horizontally placed test panel which is afterwards put into a vertical position or using a spray gun for application on a substrate in a vertical position. This International Standard is applicable to liquid coatings only.
