Abstract

The lack of intercomparisons in surface tension measurements, and the need to establish the degree of equivalence of such measurements, lead to a comparative study on this subject carried out by 3 National Metrology Institutes (from Poland, Portugal, and Turkey), within the scope of the Project 17RPT02-rhoLiq. For this purpose, the surface tension of 6 liquids, was determined at 20 °C, using force tensiometers, with 2 different measuring probes (Du Noüy ring and Wilhelmy plate), and by applying different correction factors. The results of this work allowed to conclude on the degree of equivalence of surface tension measurement results, obtained by each NMI, by using different probes and measurement models.

表面张力测量 - 对比研究

由于缺乏表面张力测量的相互比较，以及需要确定此类测量的等效程度，3 个国家计量研究院（分别来自波兰、葡萄牙和土耳其）在 17RPT02-rhoLiq 项目范围内就这一主题开展了一项比较研究。为此，使用拉力张力计和两种不同的测量探头（杜诺伊环和威尔海米板），并应用不同的修正系数，测定了 6 种液体在 20 °C 时的表面张力。根据这项工作的结果，可以得出结论：使用不同的探头和测量模型，每种 NMI 所获得的表面张力测量结果的等效程度。

期刊介绍： The main goal of this journal is the enhancement of academic activities of IMEKO and a wider dissemination of scientific output from IMEKO TC events. High-quality papers presented at IMEKO conferences, workshops or congresses are seleted by the event organizers and the authors are invited to publish an enhanced version of their paper in this journal. The journal also publishes scientific articles on measurement and instrumentation not related to an IMEKO event.
