: Results are typically reported to the nearest 0.05% or 0.1% , depending on the equipment used. Key Technical Details ASTM D95-13(2018).pdf
Q: What are the applications of ASTM D95? A: The test method has applications in crude oil quality control, pipeline and transportation monitoring, storage tank monitoring, and regulatory compliance.
Typically a short-neck, round-bottom flask (500 mL or 1000 mL) or a metal still.
The test determines the water content in a variety of petroleum products, lubes, tallows, and bituminous materials within the range of 0% to 25% water by volume. Scope and Applications
A specialized glass trap (often a Dean-Stark apparatus) graduated from 0 to 2 mL, 5 mL, 10 mL, or 25 mL, depending on the expected water content. Astm D95 Pdf
Refining crude oil with high water content causes rapid pressure spikes in distillation columns, putting refinery infrastructure at risk of explosions or emergency shutdowns. ASTM D95 vs. Karl Fischer Titration (ASTM E203 / D6304)
Best for trace amounts of water (ppm levels up to 2%). It is highly sensitive but can suffer from chemical interferences caused by additives or mercaptans in the petroleum sample. How to Access the Official ASTM D95 PDF
The full, official document contains proprietary information protected by international copyright laws. It includes exhaustive details regarding equipment dimensions, precision limits (repeatability and reproducibility criteria), and specialized troubleshooting protocols.
Crude oil contracts strictly regulate allowable basic sediment and water (BS&W) percentages. Buyers do not want to pay crude oil prices for water. ASTM D95 provides the legal benchmark data required for billing accuracy. Refining Efficiency : Results are typically reported to the nearest 0
To ensure precision and avoid common laboratory errors, implement these practices:
is the globally recognized Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation. It is a critical procedure used in the oil and gas industry to accurately measure water content, which directly impacts the quality, safety, and price of petroleum products during refining and trade. Core Method Overview The process uses a Dean-Stark distillation technique.

The American Society for Testing and Materials (ASTM) is a globally recognized leader in the development and delivery of voluntary consensus standards. Among its vast collection of standards, ASTM D95 stands out as a crucial test method for the petroleum industry. This article provides an in-depth look at ASTM D95, exploring its significance, test procedure, and applications. Typically a short-neck, round-bottom flask (500 mL or
ASTM D95, formally titled the "Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation," is an internationally recognized standard published by ASTM International. This method uses azeotropic distillation to quantify the volume of water present in a sample. The standard specifies a working range from , making it particularly useful for samples with relatively higher moisture content. Because of its direct, visual, and reliable measurement technique, it is a cornerstone procedure in quality control and material evaluation laboratories worldwide.
The co-distilled solvent and water vapors pass into a condenser and liquefy.
The percentage of water is calculated based on whether the original sample was measured by volume or by weight.
