Typically a glass round-bottom or short-neck flask ranging from 500 mL to 1000 mL in capacity, or a metal still for bituminous materials. Astm D95 Pdf
An electric mantle or gas burner capable of precise temperature control.
ASTM D95 is a proprietary standard published by ASTM International. For the exact procedural steps, precision data, and official wording, consult the latest ASTM D95 standard document available from ASTM International.
Read the volume of the accumulated water layer at the bottom of the graduated trap directly from the meniscus. 📊 Calculating the Results This test method is applied to a broad
While ASTM D95 is highly reliable, it is important to understand when to use it over alternative methods like Karl Fischer (KF) titration. ASTM D95 (Distillation) Karl Fischer (Titration) High moisture levels (0.05% to 25%) Trace moisture levels (ppm to 5%) Sample Suitability Heavy oils, crude, bitumen, tars Light fuels, solvents, clean lubricants Interferences Minimal chemical interference Highly sensitive to sulfur and additives Execution Time 1 to 2 hours 5 to 10 minutes 🔍 How to Find and Download the Official ASTM D95 PDF
The ASTM D95 test method covers the determination of water in the range of 0% to 25% volume in petroleum products, asphalts, and bituminous materials.
The trap collects the condensed liquids and allows for measurement. Traps come in various capacities (e.g., 2 mL, 5 mL, 10 mL, or 25 mL) with distinct graduation marks to handle different expected water volumes accurately. Bituminous materials, tars, and asphalts
ASTM D95 specifies several acceptable solvent-carrier liquids, including: [20†L80-L89]
Crude oil is sold by volume; however, water content (often referred to as Basic Sediment and Water, or BS&W) is an impurity. Buyers utilize ASTM D95 to ensure they are paying for oil, not water.
ASTM D95 is a standardized distillation method used to determine water content in petroleum products and bituminous materials ranging from 0% to 25%. It serves as a critical, technically equivalent, industry benchmark for quality control in lab settings, aligning with ISO 3733 and IP 74 standards. For more details, visit ANSI Webstore .
