The standard, titled the "Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation," is a critical laboratory protocol used globally to determine moisture levels in fuels, lubricants, and tars. This method is essential for industries where water contamination can degrade product quality, cause equipment corrosion, or lead to inaccurate volume calculations during trade. Scope and Applicability
The method relies on to separate water from a sample. It is effective for measuring water content ranging from 0% to 25% by volume . For concentrations outside this range, or for specific materials like crude oil, alternative standards like ASTM D4006 are typically used. Astm D95 Pdf
