ASTM D1319 is a standard test method for determining hydrocarbon types in liquid petroleum products by fluorescent indicator adsorption. It is used to help characterize the relative amounts of hydrocarbon classes in a sample, supporting more informed product evaluation and quality control. By providing a defined laboratory approach, ASTM D1319 helps users compare results consistently across testing programs and align reporting with an established ASTM standard for petroleum analysis.

Purpose of ASTM D1319

The purpose of this standard is to describe a test method for identifying hydrocarbon types in liquid petroleum products using fluorescent indicator adsorption. Its technical context is focused on compositional characterization rather than general product performance. ASTM D1319 gives laboratories and technical teams a common procedure for separating and evaluating hydrocarbon groupings in a sample, which can support consistent measurement, comparison, and documentation in routine petroleum testing workflows.

Common use cases of ASTM D1319

This standard is commonly used in laboratory and quality control settings where liquid petroleum products need compositional review. It may be applied during incoming inspection, product release testing, or comparative evaluation of petroleum samples. ASTM D1319 is especially relevant when a test report must reflect hydrocarbon type information in a clear, repeatable way. It is a practical reference for analytical workflows centered on petroleum product characterization and specification compliance.

Why ASTM D1319 matters

ASTM D1319 matters because hydrocarbon type information can influence how a liquid petroleum product is evaluated, handled, and compared against requirements. Using a recognized test method helps reduce variation between laboratories and supports more consistent procurement and compliance decisions. For organizations that rely on analytical data, the standard provides a dependable basis for quality control, product assessment, and technical communication across testing and supply chains.
