General Information

Overview
ISO 13061-12:2017 is an internationally recognized standard developed by the International Organization for Standardization (ISO) that specifies a test method for determining the static hardness of wood. This method focuses on measuring the resistance of small clear wood specimens to penetration by a plunger under a gradually increasing load. The standard is part 12 of the ISO 13061 series, which covers physical and mechanical properties of wood through test methods for small clear wood specimens.
By providing a precise and repeatable procedure for assessing static hardness, ISO 13061-12:2017 supports quality control and material evaluation in timber and wood-based industries globally.
Key Topics
- Scope and Purpose: Defines the method to quantify static hardness by applying a gradually increasing load to a plunger that penetrates the wood specimen.
- Sample Preparation: Test pieces must be clear wood sections in prism shape with a square cross-section of 50 mm × 50 mm and minimum length of 50 mm along the grain. Moisture content requirements include testing in green or air-dry conditions, with specific conditioning guidelines.
- Equipment: Uses a testing machine capable of precise load application and a hemispherical plunger with a radius of 5.64 mm ± 0.01 mm. The testing apparatus must measure both load and penetration depth accurately.
- Testing Procedure: Load is applied at a constant speed (3 mm/min to 6 mm/min) until the plunger achieves an indentation depth equal to the radius of the hemispherical tip or encounters splitting. Load is recorded at maximum penetration to determine static hardness.
- Calculations: Static hardness is expressed as the load required to achieve an indentation with a projected area of 1 cm². Calculations consider penetration depth and moisture content adjustments, typically normalized to 12% moisture content when applicable.
- Test Reporting: Specifies comprehensive reporting requirements including sample sizes, moisture content, penetration depth, test speed, and statistical analysis of results.
Applications
ISO 13061-12:2017 provides valuable insights into the mechanical behavior of wood, lending crucial support for:
- Wood Product Manufacturing: Ensuring consistency and mechanical performance in furniture, flooring, and structural timber products.
- Quality Control and Material Assessment: Evaluating wood hardness for grading, suitability for specific applications, and durability assessment.
- Research and Development: Characterizing wood materials to optimize processing techniques and develop enhanced wood composites.
- Regulatory and Certification Bodies: Standardized testing supports compliance with international timber standards and certification schemes.
This test method plays a key role in optimizing wood usage by quantifying a fundamental mechanical property relevant for end-use performance and safety.
Related Standards
ISO 13061-12:2017 integrates with and references several important standards within the ISO 13061 series and related documentation:
- ISO 13061-1: Determination of moisture content for physical and mechanical tests of small clear wood specimens.
- ISO 13061-2: Determination of density for physical and mechanical tests of wood specimens.
- ISO 3129: Wood sampling methods and general requirements for physical and mechanical tests, ensuring representative and consistent sample preparation.
- ISO 24294: Timber vocabulary, providing definitions for terms related to wood and wood-based products.
Compliance with these standards ensures comprehensive evaluation of wood properties with consistent and internationally accepted methodologies.
By adhering to ISO 13061-12:2017, wood scientists, engineers, and quality professionals can reliably measure static hardness - a key mechanical characteristic that supports sound decision-making in timber utilization, enhancing product quality and advancing sustainable forestry and manufacturing 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.
