UOP 587-92 is a laboratory test method for Acid Number and Naphthenic Acids by Colorimetric Titration, giving petroleum and chemical teams a practical way to evaluate acidity-related properties in a sample. For buyers comparing analytical methods, this standard helps define a controlled approach to identifying and measuring acidic behavior that can matter in refining, product quality review, and sample acceptance work. UOP 587-92 is most relevant when consistent laboratory documentation and comparable results are needed for technical decision-making, especially where acidity can affect materials performance or process suitability.

UOP 587-92 method scope

This UOP method focuses on the colorimetric titration approach for assessing acid number and naphthenic acids in a petroleum or related chemical sample. As a UOP test method, it is best viewed as a measurement-oriented analytical procedure used to support laboratory evaluation rather than a broad product specification. UOP 587-92 is suited to organizations that need a defined method for acidity-related characterization, method selection, or internal quality documentation. Its scope is centered on analytical determination of acid-related components as indicated by the official title.

Where is UOP 587-92 used?

UOP 587-92 is commonly used in petroleum laboratories, refinery QA/QC groups, and analytical chemistry teams that review acid number or naphthenic acid behavior in process or product samples. It may also be relevant to technical reviewers and fuel or refining specialists who need a recognized laboratory method for comparing results across batches or sites. In practice, this type of standard supports routine sample evaluation, troubleshooting, and technical reporting where acidity is a meaningful quality or compatibility factor. It is especially useful in environments that rely on consistent UOP method references.

Why professionals use UOP 587-92

Professionals use UOP 587-92 because acidity-related testing can influence product handling, corrosion awareness, and quality interpretation in petroleum work. A defined method helps laboratory analysts and refinery teams maintain consistency when comparing samples, reviewing trends, or documenting results for internal records. UOP 587-92 also supports clearer communication between testing teams and engineering or quality personnel by providing a shared analytical reference. For organizations that depend on repeatable laboratory data, this method can improve confidence in acid number and naphthenic acid evaluation without adding unnecessary complexity.
