Standard Test Method for
Salts in Crude Oil (Electrometric Method)1

This standard is issued under the fixed designation D 3230; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This test method covers the determination of the approximate chloride (salts) concentration in crude oil. The range
of concentration covered is 0 to 500 mg/kg or 0 to 150 lb/1000
bbl as chloride concentration/volume of crude oil.

1.2 This test method measures conductivity in the crude oil
due to the presence of common chlorides, such as sodium,
calcium, and magnesium. Other conductive materials may also
be present in the crude oil.

1.3 The values stated in SI units are regarded as standard.
Acceptable concentration units are g/m3 or PTB (lb/1000 bbl).

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. For specific
warning statements, see 7.3, 7.4, and 7.11.
