Methods of test for petroleum and its products. BS 2000-438. Petroleum products. Determination of content. Coulometric Karl Fischer titration method Ingestion-build-146508 and the total nonconformity beyond1 Scope This International Standard specifies a method for the direct determination of water in petroleum products boiling below 390 C. It covers the mass fraction range 0,003 % (m m) to 0,100 % (m m). It is not applicable to products containing ketones or to residual fuel oils. This International Standard may be applicable to lubricating base oils. However, the precision has not been established for these materials. The precision given in clause 12
