液体粘附或“湿润”薄片表面或被该表面吸收或两者兼而有之的性质，在纸张制造和转化的许多方面以及许多转化纸产品的最终用途中都很重要。本试验方法是一种自动接触角测量方法，适用于界面接触角从接近零到接近180°的各种片状材料和液体。

The property of a liquid to adhere to, or "wet," a sheeted surface, or to be absorbed by that surface, or both, is important in many aspects of paper manufacturing and converting, as well as in the end use applications of many converted paper products.This test method is an automated approach to contact angle measurement applicable to a wide range of sheeted materials and liquids where interfacial contact angles range from near zero to near 180°.
