If you have searched for the term , you are likely looking for the official document, a technical summary, or a way to understand its contents before purchasing. This article serves as a comprehensive guide to the ASTM D95 standard, explaining its methodology, applications, and how to legitimately access the PDF.
ASTM D95 covers the determination of water in crude petroleum, tars, and other petroleum products. It is applicable to materials where water is a distinct phase and not chemically combined with the sample. The method is capable of determining water content ranging from trace amounts up to significant percentages, typically exceeding 0.1% by volume. Astm D95 Pdf

The ASTM D95 glassware set typically includes a glass or metal still (boiling flask), an electric heater or burner, a reflux condenser, and the graduated trap. Maintaining is essential for accuracy and safety, often requiring ground glass joints or O-rings for metal-to-glass connections. A thin film of stopcock grease is recommended to prevent these joints from "freezing" or seizing during the high-heat process. Industrial Significance and Quality Control
ASTM D95 is a standardized distillation method used to measure water content (0–25% by volume) in petroleum products and bituminous materials, crucial for ensuring quality and accurate custody transfer. Utilizing the Dean-Stark principle, this method employs solvent reflux to separate water, preventing operational hazards like corrosion and refining inefficiencies. For technical specifications and the full standard, refer to Shanghai Minglan Chemical Co.,Ltd.
The volume of the separated water is measured directly from the graduations on the trap and expressed as a percentage of the original sample volume. Apparatus and Safety
