While ASTM D95 is a reliable workhorse for industrial laboratories, it is helpful to understand how it compares to alternative testing methods: Method Standard Optimal Range Best Used For Distillation 0.05% to 25% Astm D95 Pdf
The volume of water is read directly from the graduated markings on the trap. Importance in Industry
ASTM D95 is a standardized test method used to determine the water content of petroleum products and certain bituminous materials by the laboratory distillation of a measured sample. It is widely applied for fuels (gasoline, diesel, kerosene), lubricating oils, fuel oils, and bituminous binders where bound or free water may be present. The method separates volatile hydrocarbons and other constituents from water by heating the sample under controlled conditions and collecting the distilled water. Results are usually reported as percent mass (w/w) of water in the original sample. A glass receiver (usually 2 mL to 25

Water contamination in petroleum products and bituminous materials can lead to severe operational issues, including corrosion, reduced lubrication efficiency, and catalyst poisoning in refining processes. Consequently, the accurate measurement of water content is a fundamental requirement in the petroleum industry.
ASTM D95 is jointly sponsored by ASTM Committee D02 on Petroleum Products and Lubricants and the API Committee on Petroleum Measurement, ensuring its relevance across both standardization and industry practice. The standard also carries several parallel designations:
