Paints and varnishes - Wettability - Part 3 : determination of the surface tension of liquids using the pendant drop method
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 rheology[1].NOTE For other methods to determine the surface tension, see e.g. EN 14370 and ISO 1409.[1] This term is defined in DIN 1342-1.

This document 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. If applied to liquids with non-Newtonian flow behaviour (as defined in ISO 3219-1:2021, 3.22), restrictions can apply. NOTE For other methods to determine the surface tension, see e.g. EN 14370 and ISO 1409.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
With Requirements, quickly access the main part of the normative text!
