BS ISO 19403-3:2017规定了用光学方法测量液体表面张力的试验方法 使用吊坠。该方法可用于液体涂层材料的表征。 适用性可能会受到非牛顿流变性液体的限制1）。注:关于测定表面张力的其他方法，参见EN 14370和ISO 1409。交叉引用:ISO 2811（所有部分）ISO 4618:2014 ED2ISO 15528:2013 ED2ISO 19403-1:2017 ISO 19403-4:2017DIN 1342-1:1983（英译）ISO 19403-2:2017ISO 1409:2006 Ed 5ISO 19403-5:2017ISO 3270:1984（R08）ISO 5725-2EN 14370:2004ISO 2808:2007 Ed 4（R10）购买本文件时，包括所有当前可用的修改件。

BS ISO 19403-3:2017 specifies a test method to measure the surface tension of liquids with an optical method using the pendant drop. The method can be applied for the characterization of liquid coating materials. The applicability can be restricted for liquids with non-Newtonian rheology1).NOTE For other methods to determine the surface tension, see e.g. EN 14370 and ISO 1409.Cross References:ISO 2811 (all parts)ISO 4618:2014 ED2ISO 15528:2013 ED2ISO 19403-1:2017 ISO 19403-4:2017DIN 1342-1:1983 (Eng Trans)ISO 19403-2:2017ISO 1409:2006 Ed 5ISO 19403-5:2017ISO 3270:1984 (R08)ISO 5725-2EN 14370:2004ISO 2808:2007 Ed 4 (R10)All current amendments available at time of purchase are included with the purchase of this document.
