About This Item
ASTM D8193 is a standard test method for measuring total oil and grease (TOG) and total petroleum hydrocarbon (TPH) in water and wastewater using solvent extraction with non-dispersive mid-IR transmission spectroscopy. It provides a defined laboratory approach for evaluating hydrocarbon-related contamination in liquid samples, helping users obtain more consistent results for monitoring, reporting, and decision-making. For organizations that rely on analytical testing, ASTM D8193 supports a more structured path to comparable measurements.
Purpose of ASTM D8193
The purpose of ASTM D8193 is to describe a test method for determining TOG and TPH in water and wastewater through solvent extraction followed by non-dispersive mid-IR transmission spectroscopy. This technical framework is designed to help laboratories and end users measure these constituents in a repeatable way. As an ASTM standard, it gives a clear reference for sampling and analysis workflows where oil-and-grease or petroleum-hydrocarbon results need to be handled consistently.
Common use cases of ASTM D8193
This standard is commonly used in water-quality testing, wastewater monitoring, and laboratory analysis where oil and grease or petroleum hydrocarbons may be present. It is relevant for environmental testing programs, industrial discharge monitoring, and other workflows that involve liquid samples requiring solvent extraction and infrared-based measurement. ASTM D8193 is especially useful when organizations need a recognized method to evaluate contamination trends or verify analytical results across routine testing programs.
Why ASTM D8193 matters
ASTM D8193 matters because it helps support consistent testing practices for TOG and TPH measurements in water and wastewater. A defined standard can improve comparability between laboratories, strengthen quality control, and support compliance-oriented reporting. It also helps reduce uncertainty in procurement and method selection by giving buyers and technical teams a clear document to reference when they need a recognized approach for oil and hydrocarbon analysis.
