UOP 358-64 is a petroleum laboratory method for determining the bromine index of liquid butane and petroleum distillates by coulometric titration. For buyers evaluating analytical standards, this method is relevant when a plant or lab needs a controlled way to assess unsaturation-related quality in light hydrocarbon and distillate samples. It supports refinery QA/QC, fuel testing, and product review where a consistent bromine index result may help with specification checks, batch comparison, and technical documentation. UOP 358-64 is a practical fit for teams that rely on repeatable laboratory analysis for product verification.

Overview of UOP 358-64

UOP 358-64 is a UOP test method focused on measurement of the bromine index in liquid butane and petroleum distillates. As an analytical chemistry method, it provides a standardized approach for evaluating samples where bromine index is an important quality indicator. The official scope makes it most relevant to petroleum and fuel laboratories handling light hydrocarbon streams, distillate products, or similar process samples. For technical teams, the method helps align test results with a recognized procedure for comparison, reporting, and internal quality control.

Laboratory use of UOP 358-64

In practice, UOP 358-64 is commonly used by laboratory analysts, refinery quality control personnel, and technical reviewers who work with liquid butane or petroleum distillates. It may also support petrochemical and fuel-testing workflows where bromine index data is needed for sample evaluation or product comparison. Because the method is tied to a specific analytical measurement, it is useful in environments that require structured lab documentation and consistent interpretation across batches or supply streams. It can also assist engineering and quality teams reviewing product suitability.

Why UOP 358-64 matters in day-to-day work

UOP 358-64 matters because it gives laboratories a defined method for a specific quality check that can influence product handling and review decisions. When teams need dependable bromine index results, a recognized test method supports consistency across analysts, instruments, and reporting cycles. That consistency is valuable for QA/QC programs, incoming sample checks, and internal technical signoff. UOP 358-64 also helps reduce ambiguity in documentation, making it easier for laboratories and refinery teams to compare data and maintain orderly testing records.
