ISO 9117-5:2012规定了一种确定涂层（包括使用多涂层系统生产的涂层）是否达到不同干燥阶段的方法。此外，它允许评估干燥速度。 对于塑料涂层，只能在有限的范围内确定是否已达到后期干燥阶段，因为无法根据涂层表面的临时可见变化来评估这些涂层的弹塑性行为。

ISO 9117-5:2012 specifies a method for determining whether coatings, including those produced using multi-coat systems, have reached various stages of drying. Furthermore, it allows the drying speed to be assessed. In the case of plastic coatings, it is only possible to determine to a limited extent whether the later stages of drying have been reached, as the elasto-plastic behaviour of these coatings cannot be evaluated on the basis of a temporary visible change in the coating surface.
