Overview

SIST EN 14081-2:2010/kFprA1:2012 is a European standard developed by CEN’s Technical Committee TC 124, focusing on machine grading of strength graded structural timber with rectangular cross sections. This standard sets forth additional requirements for initial type testing of timber that is strength graded using machines. It complements and expands upon the general requirements detailed in EN 14081-1.

The scope of this standard covers timber shaped by sawing, planing, or other methods, ensuring that the graded timber's dimensions are in compliance with deviations allowed according to EN 336. It is specifically concerned with strength grading machines, test equipment, and proof loading graded materials used during initial type testing.

Key Topics

• Initial Type Testing Requirements
  Defines mandatory procedures and standards for conducting initial type testing of machine graded structural timber to verify accuracy and reliability.

• Machine Grading Systems
  Outlines performance criteria and operational parameters for strength grading machines used in assessing timber quality.

• Test Equipment Standards
  Details the technical specifications and calibration requirements for equipment used in load testing and grading verification.

• Dimensional Deviations
  Sets acceptable tolerance levels for timber cross-sectional dimensions, based on EN 336 specifications, enabling uniformity in grading and machining processes.

• Normative References Update
  Incorporates amendments to normative references, ensuring alignment with the latest versions of related standards such as EN 14081-1.

Applications

• Structural Timber Quality Assurance
  SIST EN 14081-2:2010/kFprA1:2012 is pivotal for manufacturers, graders, and testing laboratories to ensure structural timber meets specified strength criteria before use in construction.

• Machine Grading Process Validation
  Enables grading machine operators to verify and maintain the precision of grading results, contributing to consistent product performance.

• Construction and Timber Engineering
  Supports construction professionals by providing assurance that timber components used in load-bearing structures conform to regulated strength classifications.

• Certification and Compliance
  Assists certification bodies in approving grading systems and test equipment, facilitating compliance with European timber construction regulations.

Related Standards

• EN 14081-1: Timber Structures - Part 1: General Requirements
  The foundational standard on strength graded structural timber serving as the baseline document for grading procedures.

• EN 336: Structural Timber - Sizes
  Specifies the nominal sizes and permissible deviations for structural timber, which EN 14081-2 references for defining dimension tolerances.

• EN 1912: Structural Timber - Strength Classes - Assignment Rules
  Provides guidelines for assigning timber strength classes essential for grading conformity.

• EN 408: Timber Structures - Structural Timber and Glued Laminated Timber - Determination of Some Physical and Mechanical Properties
  Describes test methods for physical and mechanical properties that complement grading procedures.

---

By adhering to SIST EN 14081-2:2010/kFprA1:2012, stakeholders in the timber industry can ensure machine grading accuracy, enforce consistent material quality, and maintain compliance with European structural safety standards. This standard is essential for advancing the reliability of structural timber products used across various construction applications.
