Abstract
Overview
ISO 10337:1997 specifies a coulometric Karl Fischer titration method for the direct determination of water in crude petroleum. The method covers typical oil laboratory practice, defining sampling, sample handling, apparatus, reagents and the titration procedure. It is intended for water contents in the range from about 0.02 % to 5.00 % (m/m) depending on the level of interfering sulfur species (mercaptans or ionic sulfides). The standard also includes a normative Annex A on sample handling and an informative Annex B describing an alternative volumetric test-portion measurement.
