GSO ASTM D6304:2022 Scope
1.1 This test method covers the direct determination of
water in the range of 10 mg ⁄kg to 25 000 mg ⁄kg entrained
water in petroleum products and hydrocarbons using automated instrumentation. This test method also covers the
indirect analysis of water thermally removed from samples and
swept with dry inert gas into the Karl Fischer titration cell.
Mercaptan, sulfide (S− or H2S), sulfur, and other compounds
are known to interfere with this test method (see Section 5).
1.2 This test method is intended for use with commercially
available coulometric Karl Fischer reagents and for the determination of water in additives, lube oils, base oils, automatic
transmission fluids, hydrocarbon solvents, and other petroleum
products. By proper choice of the sample size, this test method
may be used for the determination of water from mg/kg to
percent level concentrations.
1.3 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
standard.
1.4 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.
