General Information

Overview
EN 14081-2:2018/FprA1 is a key European standard developed by CEN (European Committee for Standardization) that focuses on strength grading of structural timber with rectangular cross-sections. Specifically, this part of the EN 14081 series addresses machine grading and establishes additional requirements for type testing of these machine-graded timbers. The standard applies to timber shaped by sawing, planning, or other shaping methods, with size deviations conforming to EN 336.
This amendment to the original 2018 standard outlines enhanced verification protocols for machine grading equipment to ensure consistent, reliable measurement of timber strength characteristics-critical for safe timber construction.
Key Topics
Type Testing Requirements
EN 14081-2 defines additional type testing criteria beyond those set by EN 14081-1 to ensure grading machines reliably classify wood according to strength classes.Sampling Procedures
The standard requires random sampling of at least 40 specimens per grade, species, size, and timber source, emphasizing thorough statistical validation of grading accuracy.Machine Settings Verification
Verification is mandatory for all machine settings where characteristic mechanical properties-such as bending strength, tension strength, density, and modulus of elasticity-must meet or exceed declared class values. Settings must be re-adjusted if verification fails, and the process repeated.Output-Controlled Systems
The document references EN 14081-3 regarding verification procedures for output-controlled grading systems, stressing the importance of integrated quality control mechanisms.Scope of Application
Applies to rectangular cross-section timber used for load-bearing structural purposes, serving industries involved in timber construction, manufacturing, and quality assurance.
Applications
EN 14081-2 is essential for anyone involved with the production, grading, and certification of structural timber used in construction:
Timber Manufacturers and Processors
Ensures that machine grading systems deliver consistent quality and classification, improving throughput and reducing human error.Construction Industry
Provides assurance that timber used in building frameworks meets required strength criteria for safety and durability.Certification Bodies and Inspectors
Standardizes methods for testing and verifying grading machines to uphold market trust and regulatory compliance.Research and Development
Facilitates advancement in machine grading technologies and the development of new grading algorithms compliant with European regulations.
Related Standards
EN 14081-1: This part outlines the general principles for strength grading of structural timber, serving as the foundational standard to which EN 14081-2 adds detailed type testing and machine grading requirements.
EN 14081-3: Specifies verification procedures for output-controlled grading systems, referenced within EN 14081-2 to guide sampling and verification logistics.
EN 336: Establishes nominal sizes and size deviations for structural timber cross-sections, the dimensional reference framework for timber graded under EN 14081 series.
Adherence to EN 14081-2:2018/FprA1 supports compliance with European timber grading regulations, enhances machine grading reliability, and promotes the structural safety of timber constructions across Europe. It is a crucial standard for ensuring precision in modern machine-based timber grading systems used in the wood industry today.
