General Information

Overview
ISO 13061-17:2017 is an international standard developed by the International Organization for Standardization (ISO) that defines test methods for determining the ultimate stress in compression parallel to the grain of small clear wood specimens. This standard provides a precise and reliable methodology to assess the physical and mechanical properties of wood, particularly focusing on its strength under compression load along the grain. It replaces ISO 3787:1976 with updated requirements on specimen size, moisture content, and adjustment for moisture effects.
This test method is fundamental for wood technology, structural engineering, and quality control processes where an accurate understanding of wood compression strength is essential. By establishing consistent test procedures, ISO 13061-17:2017 ensures comparability of data across laboratories and countries.
Key Topics
- Test Scope: Specifies how to measure the ultimate compressive stress parallel to grain on small defect-free wood specimens.
- Specimen Preparation: Requires prismatic specimens with square cross-sections at least 20 mm wide and lengths 1.5 to 4 times the side length, with considerations for growth ring widths.
- Moisture Conditioning: Specimens can be tested green (at or above fiber saturation point) or conditioned to moisture equilibrium at (65 ± 5)% relative humidity and (20 ± 2) °C.
- Test Equipment:
- Load testing machine capable of constant-load or constant-displacement application with 1% accuracy.
- Uniform loading device with hardened steel plates for even load distribution.
- Precision instruments for measuring specimen dimensions and moisture content.
- Test Procedure: Gradually apply compressive load along the grain until specimen failure, recording maximum load and test duration.
- Calculation: Ultimate stress calculated as max load divided by cross-sectional area, with potential normalization to a standard 12% moisture content using recognized national or international correction methods.
- Reporting Requirements: Comprehensive test reports must include specimen details, test conditions, moisture content, density, failure mode, and statistical analysis of results.
Applications
ISO 13061-17:2017's method for determining ultimate compressive stress parallel to grain is critical for:
- Structural Engineering: Design and safety verification of timber constructions where compressive strength along grain affects load-bearing capacity.
- Wood Material Research: Evaluating mechanical performance of new wood species, engineered wood products, or treatments.
- Quality Control: Inspection and grading of timber to ensure compliance with strength requirements.
- Product Development: Optimization of wood-based materials for applications requiring specific mechanical properties.
- Standards Harmonization: Providing a consistent test approach supports uniform assessment worldwide, facilitating international trade and certification.
The standard complements other ISO methods for wood property tests such as moisture content determination (ISO 13061-1) and density measurement (ISO 13061-2), enabling comprehensive mechanical characterization.

- ISO 24294: Wood - Round and sawn timber - Vocabulary.
- ISO 3787: Former version of the compression test method replaced by ISO 13061-17.
By integrating these standards, professionals gain a complete framework for wood mechanical property evaluation, ensuring precision, repeatability, and compliance with international best practices.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
