About This Item
ASTM D8045 is the ASTM standard for determining the acid number of crude oils and petroleum products by catalytic thermometric titration. It provides a defined test method for measuring acidity in materials where acid number can affect handling, processing, and quality evaluation. For laboratories and purchasing teams, this standard helps support consistent testing and clearer product comparisons. ASTM D8045 is especially useful when a reliable, repeatable method is needed for routine analysis and technical documentation.
What is ASTM D8045?
ASTM D8045 is a test method focused on measuring acid number in crude oils and petroleum products using catalytic thermometric titration. In practical terms, it describes a standardized way to assess the acidic character of these materials through a controlled laboratory procedure. The standard is intended to support consistent analytical results and help users compare samples under the same method conditions. As an ASTM standard, it serves as a technical reference for laboratories, quality programs, and product evaluation workflows.
Where is ASTM D8045 used?
This standard is commonly used in laboratory environments that test crude oils and petroleum products for acidity-related properties. It may be applied in quality control, incoming inspection, routine product verification, or research and development settings where acid number is part of the evaluation. ASTM D8045 is relevant wherever catalytic thermometric titration is used as the chosen test approach, helping ensure that the same method is followed across different samples, batches, or testing locations.
Why is ASTM D8045 important?
ASTM D8045 matters because acid number results can influence decisions about product acceptance, processing suitability, and overall material consistency. A standardized test method helps reduce variation between laboratories and supports more dependable comparisons over time. For organizations that rely on analytical data, the standard can aid compliance efforts, procurement review, and quality control programs. Using ASTM D8045 also helps create a clearer technical record when documenting petroleum product performance.
