Astm D95 Pdf ~upd~ Jun 2026
The core principle behind ASTM D95 is the azeotropic distillation of the test sample with a water-immiscible solvent. The apparatus used is the .
is the standardized test method for determining water content in petroleum products, tars, and other bituminous materials by the distillation method . Officially titled "Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation," it is one of the most referenced methods in crude oil, fuel, and asphalt testing.
However, ASTM D95 remains the method of choice when:
This comprehensive guide covers the technical specifications, apparatus setup, procedural steps, and industrial significance of the ASTM D95 test method. 📌 What is ASTM D95? Astm D95 Pdf
The test requires a distillation flask, reflux condenser, and a graduated trap (Dean-Stark apparatus) to separate and measure the water content. The process involves heating the sample with a volatile solvent to distill the water, which is then measured in the trap.
To perform this test according to the standard, labs typically use a specialized apparatus consisting of:
Executing an ASTM D95 test requires a specific glassware configuration. A standard setup consists of the following components: The core principle behind ASTM D95 is the
ASTM D95, formally titled Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation , is a classic standardized test method used to determine the water content of these materials. While the standard is often sought after in digital format (PDF) for quick reference, understanding the technical intricacies of the procedure is essential for accurate implementation. This paper explores the technical aspects of the standard, emphasizing the scientific principles behind the distillation method.
The combined solvent and water vapors travel upward into a reflux condenser, where they liquefy.

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). Officially titled "Standard Test Method for Water in
While the official ASTM standards are copyrighted and require purchase, there are several legitimate ways to access ASTM D95 content for free or at reduced cost.
. This measurement is critical for "custody transfer"—the legal and financial point where petroleum products change ownership—as it allows parties to correct the volume for actual product versus water content. 分析测试百科网 Interesting Procedural Details The "Co-Distillation" Trick : The sample is heated under reflux with a water-immiscible solvent
