Astm D95 Pdf Instant
If water droplets adhere to the sides of the glass trap, push them down into the water layer using a copper wire or glass rod wetted with solvent.
Look for the current active version designation (e.g., ASTM D95-13R18, where the number after the hyphen indicates the year of original adoption or latest revision).
: Distillates, fuel oils, and lubricating oils. Bituminous Materials : Tars, asphalts, and related mixtures.
A glass reflux condenser (usually a straight-tube or Liebig type) with a jacket length of 400 mm ensures complete condensation of volatile vapors. 3. Graduated Glass Trap Astm D95 Pdf
Legally, no. Copyright law protects ASTM standards. However, many public technical libraries or university engineering departments provide access for reading. Some ASTM standards are also available for viewing at designated "Reading Rooms" without download rights.
Specific mixtures targeted for highly viscous or volatile asphalt samples. 4. Step-by-Step Test Procedure
The water content is calculated as either a volume percentage or a mass percentage, depending on how the initial sample was measured. Volume Percentage Formula: If water droplets adhere to the sides of
The method is elegantly simple: when a water-immiscible solvent is heated with a sample, the solvent and water co-distill. Because water and the solvent don't mix, they separate upon condensation, allowing the water to be collected and measured directly. [21†L4-L9]
: Refineries use the test to ensure that crude oil feedstocks meet quality specifications, helping to prevent operational issues and ensure the production of high-quality products.
ASTM D95 is used to measure water volume, specifically within a range of , which is critical for refining, product valuation, and safe handling of petroleum and bitumen products. The principle involves heating the sample with a water-immiscible solvent (like xylene) and measuring the water collected in a calibrated trap via a Dean-Stark apparatus. Procedure and Equipment Bituminous Materials : Tars, asphalts, and related mixtures

Searching for is the first step toward mastering water determination in petroleum products. However, nothing replaces the official document. The PDF contains critical details omitted in summaries, such as:
: A sample is heated under reflux with a water-immiscible solvent (like xylene or toluene) that co-distills with the water.
