标准范围

ISO 19403-7:2017规定了一种动态测量固体表面上液滴滚转角的方法。通过动态测量,还可以确定液滴滚动的前进角和后退角。例如,在评估易清洁表面或防粘表面时,滚落角度起着一定作用。

ISO 19403-7:2017 specifies a method for the dynamic measurement of the roll-off angle of a liquid drop on a solid surface. From the dynamic measurement, the advancing and receding angles of the drop rolling off can also be determined. The roll-off angle plays a role when evaluating, for example, easy-to-clean or anti-adherent surfaces.
