ASTM D1492 is the ASTM standard for the Standard Test Method for Bromine Index of Aromatic Hydrocarbons by Coulometric Titration. It provides a technical basis for measuring bromine index in aromatic hydrocarbon materials using a coulometric titration approach, helping users evaluate sample quality and chemical behavior with a consistent test method. For laboratories, suppliers, and buyers working with aromatic hydrocarbons, this standard supports more reliable comparison, specification control, and routine testing.

Purpose of ASTM D1492

The purpose of this standard is to define a controlled test method for determining the bromine index of aromatic hydrocarbons by coulometric titration. As an ASTM standard, ASTM D1492 helps align testing practices so results can be generated and interpreted in a more consistent way. That makes it useful when bromine index is part of material assessment, incoming inspection, or product verification. The standard is intended to support repeatable laboratory measurement rather than informal testing.

Common use cases of ASTM D1492

This standard is commonly used in laboratory and quality control settings where aromatic hydrocarbons are evaluated for bromine index. It may be applied during material testing, batch comparison, or supplier certification work when a defined analytical method is needed. ASTM D1492 is also relevant for organizations that rely on coulometric titration equipment and need a standardized procedure for reporting results in technical or procurement documents. Its value is greatest where consistent measurement is important.

Why ASTM D1492 matters

ASTM D1492 matters because a standardized test method helps reduce variation in how bromine index is measured and reported. That consistency supports better compliance decisions, clearer specifications, and more dependable product evaluation. In practice, it can help limit disputes between buyers and suppliers, improve quality control records, and provide a dependable reference for laboratory work. Using a recognized ASTM standard also strengthens confidence in test results across different facilities.
