ASTM D847

ASTM D847 is the standard test method for acidity in benzene, toluene, xylenes, solvent naphthas, and similar industrial aromatic hydrocarbons. It provides a recognized approach for evaluating whether these materials meet expected acidity limits, which can be important for product quality and downstream use. For buyers, laboratories, and quality teams, this standard supports consistent testing and clearer acceptance decisions for aromatic hydrocarbon materials used in industrial applications.

What is ASTM D847?

ASTM D847 is a technical test method focused on measuring the acidity of selected aromatic hydrocarbon products. As titled, it applies to benzene, toluene, xylenes, solvent naphthas, and similar industrial aromatic hydrocarbons. The standard is used to help assess whether these materials contain acidic characteristics that may affect handling, storage, or suitability for use. In practice, ASTM D847 gives users a common reference for comparing test results and supporting quality control programs.

Where is ASTM D847 used?

This standard is commonly used in laboratories, refinery or petrochemical quality control settings, and purchasing or receiving inspections for aromatic hydrocarbon products. It is relevant wherever benzene, toluene, xylenes, solvent naphthas, or comparable industrial aromatic hydrocarbons are tested before use or shipment. ASTM D847 helps support routine product evaluation, specification checks, and batch-to-batch verification when acidity is a concern in material acceptance or processing.

Why is ASTM D847 important?

ASTM D847 matters because acidity can influence product performance, stability, and compatibility in industrial use. A standardized test method helps reduce variation between laboratories and makes results easier to compare across suppliers and lots. For procurement and quality control teams, ASTM D847 can support compliance checks, specification reviews, and risk reduction when evaluating aromatic hydrocarbon materials. It also provides a clearer technical basis for acceptance decisions than informal testing practices.
