ASTM D1093
1. Scope
1.1 This test method covers the qualitative determination of the acidity of hydrocarbon liquids and their distillation residues. Warning-See Note 1.
Note 1-Many hydrocarbon liquids are extremely flammable. Harmful if inhaled. Hydrocarbon liquid vapors can cause a flash fire. %1.2 If desired to determine the basicity of a hydrocarbon liquid, proceed in accordance with 8.1 or 8.2 but substitute 3 drops of phenolphthalein indicator solution for the methyl orange indicator. A pink or red color in the aqueous solution when phenolphthalein is used indicates basicity.1.3 The results obtained by this method are qualitative expressions. However, for the preparation of reagents and in the procedure, acceptable SI units are to be regarded as the standard.
1.4 This standard does not purport to address all of the safety problems, 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.
