ASTM D6470 for salt in crude oils (Potentiometric method)
1. Scope1.1 This 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).1.2 The limit of detection is 0.0002 % (m/m) for salt (as NaCl).1.3 The test method is ...

ASTM D189 for Conradson carbon residue of petroleum products
1. Scope1.1 This test method covers the determination of the amount of carbon residue (Note 1) left after evaporation and pyrolysis of an oil, and is intended to provide some indication of relative coke-forming propensities. This test method is generally applicable to relatively nonvolatile petroleum ...
