ASTM D848-09
(Test Method)Standard Test Method for Acid Wash Color of Industrial Aromatic Hydrocarbons
Standard Test Method for Acid Wash Color of Industrial Aromatic Hydrocarbons
SIGNIFICANCE AND USE
This test method is suitable for setting specifications on the materials referenced in 1.1. It may also be used as an internal quality control tool and in development or research work.
The color developed in the acid layer gives an indication of impurities which if sulfonated would cause the material to be discolored.
SCOPE
1.1 This test method covers the determination of the acid wash color of benzene, toluene, xylenes, refined solvent naphthas, and similar industrial aromatic hydrocarbons.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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 hazard statements, see Sections 8 and 12.1.
