1.1This test method covers the determination of salt in crude oils. For the purpose of this test method, salt is expressed as % (m/m) NaCl (sodium chloride) and covers the range from 0.0005 % to 0.15 % (m/m).
1.2The limit of detection is 0.0002 % (m/m) for salt (as NaCl).
1.3The test method is applicable to nearly all of the heavier petroleum products, such as crude oils, residues, and fuel oils.
