10.7.1 Scope
10.7.1.1 This section describes the procedure for the determination of water in crude oils by Karl Fischer titration (volumetric). This test method covers the determination of water in the range from 0.02 to 2 mass percent in crude oils. Mercaptan and sulfide (S= or H2S) sulfur are known to interfere with the method (see 10.7.5).
10.7.1.2 This test method is intended for use with standard Karl Fischer reagent or pyridine-free Karl Fischer reagents.
CAUTION: This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use (see Appendix A).
