ASTM D890-12(2022) PDF

Overview

ASTM D890-12(2022) - Standard Test Method for Water in Liquid Pine Chemicals - defines quantitative methods for determining water content in various liquid pine chemicals. These products include turpentine, pinene, dipentene, pine oil, tall oil, and tall oil fatty acids, which may contain dissolved or occluded water from production processes. The standard provides three recognized test methods for water quantification, ensuring product quality consistency and process reliability across industries involved with pine-derived chemicals.

Key Topics

• Test Methods Included:

  • Karl Fischer Titration (preferred for tall oil): Utilizes a chemical reaction involving iodine to precisely measure low levels of water content.
  • Coulometric Titration: Employs electronic integration for generating required iodine and reacting with water in the sample.
  • Azeotropic Distillation: Uses differences in boiling points to collect and measure water, suitable for higher moisture levels.

• Applicable Products:

  • Turpentine
  • Pinene
  • Dipentene
  • Pine oil
  • Tall oil (crude and refined)
  • Tall oil fatty acids

• Result Reporting:

  • Results expressed in SI units and reported to the nearest 0.01% or 0.1%, depending on the method used.

• Principles of Standardization:

  • Developed according to internationally recognized principles, supporting global trade and regulatory compliance.

Applications

• Quality Control in Pine Chemicals Accurate moisture determination is crucial for manufacturers and quality control laboratories to ensure product consistency in pine oil, turpentine, and related derivatives.

• Optimizing Industrial Processes Understanding water content helps optimize further processing steps and prevents issues such as unwanted reactions, product instability, or yield loss.

• Regulatory and Trade Compliance Compliance with ASTM D890-12(2022) supports international regulatory requirements and smooth facilitation of pine chemical trade, aligning with the World Trade Organization (WTO) Technical Barriers to Trade (TBT) principles.

• Laboratory Operations Laboratories performing analyses on pine chemicals require standardized, reliable methods for water detection, both for internal process control and contract testing services.

Related Standards

• ASTM D1364 - Test Method for Water in Volatile Solvents (Karl Fischer Reagent Titration Method)

Following ASTM D890-12(2022) ensures laboratory and industrial laboratories use internationally accepted methods for quantifying water in liquid pine chemicals. Adhering to these standardized test methods safeguards product quality, enhances laboratory credibility, and ensures compliance with both domestic and international regulations.
