将已知性质和特征的棉盘夹在手柄中，浸入已知浓度的表面活性剂溶液中。置换空气后，溶液渗透到布料中，棉盘开始下沉。润湿时间是通过测量棉盘浸入时刻和开始下沉时刻之间的间隔来确定的。测定两种标准溶液和五种不同浓度溶液的润湿时间，然后测定五种不同浓度的表面活性剂溶液的润湿时间。绘制并比较了三条“润湿时间/浓度”曲线。

A cotton disc of known nature and characteristics, held in a grip, is immersed in a solution of surface active agent of known concentration. After displacement of air an penetration of the solution into the cloth, the cotton disc starts to sink. The wetting time is determined by measurement the interval between the moment of immersion of the cotton disc and the moment when it begins to sink. The wetting time is determined of two standard solutions and for each of five different concentrations and then of the surface active agent solution under test for five different concentrations. The three curves "wetting time / concentration" are plotted and compared.
