ASTM D95-23 PDF

Overview

ASTM D95-23 is the internationally recognized standard test method for determining the water content in petroleum products, tars, and other bituminous materials using the distillation method. Published by ASTM International, this standard outlines a precise procedure to identify water presence in a range from 0% to 25% by volume. Accurate measurement of water content is critical in the petroleum industry for refining, purchasing, selling, and transferring petroleum products and bituminous materials.

This standard is widely used for quality control, contractual compliance, and custody transfer Applications. It supports both laboratory and field operations, ensuring consistent product quality and reliability in transactions involving petroleum products and bituminous materials.

Key Topics

• Water Determination by Distillation: Describes a method where the test sample is mixed with a water-immiscible solvent and heated under reflux. Water distills along with the solvent and is quantitatively measured in a calibrated trap.
• Range of Applicability: Measures water content in various liquid and semi-solid petroleum products, tars, and bitumen from 0% up to 25% by volume.
• Importance in Industry:
  • Determines compliance to specifications and contracts, as water content may affect product value.
  • Used for volumetric correction during the custody transfer process.
  • Supports operational decisions in refining and production.
• Accurate Reporting and Precision: Results are reported to the nearest 0.05% or 0.1% by volume, depending on the measuring trap, ensuring traceability and accuracy.
• Sampling and Verification: Specifies adherence to referenced ASTM practices for sample collection, homogenization, and calibration, maintaining integrity throughout the test process.

Applications

ASTM D95-23 is essential in various sectors within the petroleum industry, including:

• Refining Operations: Precise water measurement helps maintain product quality, avoid equipment corrosion, and prevent process inefficiencies.
• Product Specification and Compliance: Ensures products meet customer and regulatory requirements, supporting both buyers and sellers during commercial transactions.
• Custody Transfer and Logistics:
  • Used to adjust volumes for water content during the handover of product ownership.
  • Minimizes disputes and ensures fair valuation.
• Research and Quality Assurance: Laboratories employ this standard for routine analysis and special investigations related to petroleum or bituminous materials.

Through its detailed methodology and strict sampling guidelines, ASTM D95-23 promotes reproducibility and comparability of results across operators and laboratories.
