Overview

EN 14279:2004/prA1 is the CEN draft amendment addressing Laminated Veneer Lumber (LVL) definitions, classification and specifications. This European Standard (prepared by CEN/TC 112) sets out the terminology and classification system and specifies requirements for LVL intended for general purposes or for use in construction under dry, humid or exterior conditions. The prA1 amendment clarifies labelling for intended application - distinguishing "S" (structural) from "NS" (non-structural) use - and is submitted for Unique Acceptance Procedure by CEN members.

Key Topics

• Definitions: Establishes standardized terms for LVL products to ensure consistent interpretation across national standards and supply chains.
• Classification: Specifies how LVL is classified by intended application (structural vs non-structural), service condition (dry, humid, exterior) and relevant product characteristics.
• Specifications and requirements: Outlines the required information and general requirements manufacturers must declare for LVL products, supporting safe and compliant use in construction.
• Amendment detail: prA1 modifies Clause 8 to replace the labelling code "G" with "NS" to denote non-structural application; the letter "S" denotes structural application.
• Scope and applicability: Applies to LVL used for general purposes or construction, and informs national standard adoption when the amendment is approved.

Applications

EN 14279:2004/prA1 has practical value across the wood products and construction sectors:

• Architects and structural engineers: use the standardized definitions and classification to select appropriate LVL products for different service conditions.
• Manufacturers and suppliers: align product labelling and declarations with CEN requirements for market access and compliance.
• Certification and testing bodies: reference the standard when assessing LVL for intended structural or non-structural uses.
• Contractors and specifiers: apply the standard to ensure correct LVL selection for dry, humid or exterior installations.

Benefits include improved clarity in product specification, consistent labelling across Europe, and better alignment between national regulations and CEN requirements.

Related Standards

• Standards on wood-based panels and structural timber that address test methods, performance classification and durability may be referenced alongside EN 14279 for a complete compliance strategy.
• Relevant CEN/TC 112 outputs: documents covering terminology, test procedures and product marking for wood-based panels.

For practitioners, EN 14279:2004/prA1 is a central reference for LVL terminology, classification and declaration practices that supports safe, compliant use of LVL in a range of service conditions.

This draft amendment is submitted to CEN members for unique acceptance procedure. It has been drawn up by the Technical Committee
CEN/TC 112.
This draft amendment A1, if approved, will modify the European Standard EN 14279:2004. If this draft becomes an amendment, CEN
members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of this amendment
into the relevant national standard without any alteration.
This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made
by translation under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same
status as the official versions.
