UOP 46-85 is a petroleum laboratory test method for determining the paraffin wax content of petroleum oils and asphalts. For buyers evaluating analytical standards, this method is relevant when wax content needs to be understood as part of product characterization, material comparison, or quality review. It supports technical teams that work with heavy petroleum materials where wax presence can affect handling, performance, and consistency. UOP 46-85 is a practical reference for laboratory use when a defined method is needed to assess wax content in oils and asphalts.

UOP 46-85 method scope

The scope of UOP 46-85 centers on the analytical determination of paraffin wax content in petroleum oils and asphalt materials. As a UOP test method, it is intended for laboratory evaluation rather than general field screening, making it suitable for controlled technical work and documented testing programs. The method is especially relevant when a refinery or laboratory needs a consistent way to examine wax-related properties in heavy petroleum samples. It supports method selection, product review, and standardized reporting within petroleum and chemical analysis workflows.

Where is UOP 46-85 used?

UOP 46-85 is commonly used in refinery laboratories, petroleum testing labs, and technical review settings where oils and asphalts are evaluated for wax content. Laboratory analysts, refinery QA/QC teams, and petroleum specialists may rely on it when reviewing sample composition or comparing materials across batches. It is also useful for analytical chemists and process or product quality personnel who need a recognized method for wax-related characterization. In practice, it fits workflows tied to sample evaluation, documentation, and internal quality decisions.

Why professionals use UOP 46-85

Professionals use UOP 46-85 because wax content can be an important factor in petroleum material behavior and quality assessment. A defined test method helps teams produce consistent results, support product comparison, and strengthen laboratory documentation. For organizations handling oils and asphalts, the method can improve technical clarity during routine QA/QC, product review, or supplier evaluation. It is a useful reference when the goal is to apply a standardized approach to paraffin wax content analysis without relying on informal or ad hoc testing practices.
