ISO 304:1985 表面活性剂.用拉起液膜法测定表面张力
标准编号:ISO 304:1985
中文名称:表面活性剂.用拉起液膜法测定表面张力
英文名称:Surface active agents — Determination of surface tension by drawing up liquid films
发布日期:1985-12
标准范围
测量最大力,该力是垂直作用在与放置在量杯中的被检查液体表面接触的箍筋或环上,以便将其与该表面分离,或作用在边缘与该表面接触的板上,以便拉起已形成的膜所必需的。纯液体或其他溶液的表面张力也可以用这种方法测量。
The maximum force is measured which is necessary to act vertically on a stirrup or a ring, in contact with the surface of the liquid being examined placed in a measuring cup, in order to separate it from this surface, or on a plate with an edge in contact with the surface, in order to draw up the film that has formed. The surface tension of pure liquids or other solutions can also be measured by this method.
