GOST 1516.2-97 PDF

Full title and description

GOST 1516.2-97 — a Russian national standard that specifies methods for determination of moisture content in wood and wood-based materials using laboratory drying methods. It defines procedures, sample preparation, drying conditions and calculation formulas to obtain accurate moisture content expressed as a percentage of dry mass.

Abstract

This standard provides laboratory procedures for determining the moisture content of wood and wood products by oven-drying to constant mass. It covers sampling, specimen preparation, drying temperatures and durations, and calculations needed to report equilibrium and immediate moisture content. The method is intended to produce reproducible, comparable results for quality control, specification compliance and research.

Scope

GOST 1516.2-97 applies to the determination of moisture content in solid wood, wood-based panels and similar materials using an oven-drying technique. It is intended for laboratory conditions and sets out rules for sampling, conditioning, drying to constant mass, and calculation of moisture content. The standard is applicable where accurate moisture measurement is required for product specification, drying control, testing and research.

Key topics and requirements

• Sampling and preparation: guidance on representative sample selection and specimen dimensions to ensure consistent results.
• Conditioning and initial handling: procedures to avoid moisture loss/gain prior to weighing.
• Drying procedure: specified oven temperatures (commonly around 103 ± 2 °C for wood) and criteria for constant mass.
• Weighing accuracy: requirements for balances and tolerances for mass measurements.
• Calculation method: formulas to express moisture content as percentage of dry mass and to calculate mass loss during drying.
• Reporting: recommended information to include in test reports (sample description, pre- and post-dry masses, drying conditions, calculated moisture content, date and operator).
• Limitations and precautions: notes on volatile extractives, risk of decomposition at elevated temperatures, and applicability to certain wood-based products.

Typical use and users

Primary users include testing laboratories, wood product manufacturers, quality control personnel, forestry researchers, and certification bodies. Typical uses are verifying moisture specifications before processing (e.g., drying, gluing, finishing), accepting or rejecting deliveries of wood materials, research experiments, and determining moisture for seasoning or storage control.

Related standards

Standards commonly used alongside GOST 1516.2-97 include other GOST and international standards on wood moisture determination and testing, methods for sampling, and standards for specific wood products (e.g., standards for particleboard, plywood and sawn timber). Equivalent international methods include oven-drying procedures found in ISO and European standards for moisture content determination.
