API MPMS 10.9-2013 Manual of Petroleum Measurement Standards Chapter 10.9 Standard Test Method for Water in Crude Oils by Coulometric Karl Fischer Titration (Third Edition)
This test method covers the determination of water in the range from 0.02 to 5.00 mass or volume % in crude oils. Mercaptan (RSH) and sulfide (S? or H2S) as sulfur are known to interfere with this test method@ but at levels of less than 500 ??/g [ppm(m)]@ the interference from these compounds is insignificant (see Section 6). This test method can be used to determine water in the 0.005 to 0.02 mass % range@ but the effects of the mercaptan and sulfide interference at these levels has not been determined. For the range 0.005 to 0.02 mass %@ there is no precision or bias statement. This test method is intended for use with standard commercially available coulometric Karl Fischer reagent. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. This standard does not purport to address all of the safety concerns@ if any@ associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements@ see Section 8. *A Summary of Changes section appears at the end of this standard
