Overview

CEN/TS 14464:2010 is a Technical Specification published by the European Committee for Standardization (CEN) that sets out a method for the assessment of case-hardening in sawn timber. Specifically, it details a destructive test based on measuring distortion in a slice taken from a timber specimen, allowing for an accurate evaluation of case-hardening. This standard is applicable to both softwood and hardwood sawn timber, as well as timber that has been planed or otherwise surfaced, with a thickness not exceeding 100 mm.

Case-hardening, a common condition resulting from timber drying processes, poses significant challenges in woodworking and timber utilization. Accurate identification and assessment of case-hardening improves product quality, ensures structural reliability, and reduces manufacturing problems in subsequent processing stages.

Key Topics

• Destructive Test Method
  The standard specifies a slicing test method, requiring the removal of a section from the timber piece. The distortion (warping or cupping) observed in this test slice after being cut and conditioned provides an indicator of case-hardening severity.

• Applicable Timber Types

  • Sawn timber
  • Planed timber
  • Surfaced timber
  • Both softwoods and hardwoods (up to 100 mm thickness)

• Detailed Procedure

  • Selection and preparation of a test slice (15 mm length, full cross section)
  • Requirements for clean, defect-free test samples
  • Proper marking and division of the test slice
  • Moisture conditioning in sealed bags (24 hours for softwood, 48 hours for hardwood)
  • Measurement of distortion using a specially designed test jig

• Interpretation of Results
  Results are measured in millimetres, accounting for jig variables, and further calculations personalize the assessment to the width of the timber.

Applications

Implementing CEN/TS 14464:2010 brings practical benefits across the wood industry:

• Quality Control:
  The assessment method helps sawmills and timber processors detect case-hardening before further processing or sale, reducing the risk of product failure or customer complaints.

• Process Optimization:
  Identification of case-hardening informs improvements to drying and conditioning processes, such as controlling humidity and temperature cycles.

• Supplier and Purchasing Standards:
  Timber suppliers and buyers can use the standard to specify quality requirements and ensure uniformity across sourced materials.

• Research and Development:
  Standards-based testing accelerates R&D initiatives in timber treatment, drying technology, and the development of new wood-based products.

Related Standards

To ensure consistency and precise understanding, CEN/TS 14464:2010 references a range of essential terminology standards:

• EN 844 Series:
  • EN 844-1 to EN 844-12: Specific parts cover general terms, dimensions, features, anatomical structure, moisture content, stains, fungal attack, insect degradation, and additional index terms relating to round and sawn timber.

Organizations and professionals working in forestry, lumber manufacturing, and timber construction can significantly benefit from aligning with these related standards, allowing for seamless integration of timber quality assessments and improved communication across the supply chain.
