ASTM D482

Ash from Petroleum Products

Applicability: ASTM D482 is a standard test method specifically designed to determine the ash content in various petroleum products. Ash, in this context, refers to the inorganic residue left after a sample is ignited and burned until all carbonaceous material is removed. The presence of ash in petroleum products is often considered undesirable and can indicate contamination from sources like dirt, rust, or other solids.

Purpose: The primary purpose of ASTM D482 is to determine the ash content of petroleum products, which are materials like fuels, lubricating oils, and waxes.
