ASTM D848

ASTM D848 – Standard Test Method for Acid Wash Color of Industrial Aromatic Hydrocarbons

Description:

Significance and Use

5.1 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.

5.2 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.
