Abstract

Abstract: According to ISO 17025:2017, the testing laboratories are required to confirm the measurementaccuracy with proficiency testings or international comparisons. For this purpose, the proficiency testings for pHand conductivity measurements in water and soil are organized by TUBITAK UME twice a year. In this study,the preparation and analysis of the samples according to BS EN ISO 10523:2012, ISO 7888:1985, ISO10390:2005 and ISO 11265:1996 and the evaluation of the results according to ISO 17043:2010 were carriedout. pH and electrolytic conductivity (EC) values were determined by a pH meter and a conductivity meter forthis study. Based on the results of the participants, they have a chance to improve the accuracy and reliability oftheir measurement results as observing the performances of other laboratories.
