Latest Updates to European Standards

See full list of  individual standards for plywood, OSB and LVL.

As part of the official five year review process:

  • Six standards are currently under review.
  • No further standards relevant to wood-based panels have been added this year.
  • One new laminated veneer lumber standard is still under development.  It will amalgamate EN 14374 with EN 14279 to create a universal classification for structural and non-structural LVL.
Under review:

EN 318:2002 Wood-based panels – Determination of dimensional changes associated with changes in relative humidity

EN 325:2012   Wood-based panels – Determination of dimensions of test pieces

EN 14272:2011  Plywood – Calculation method for some mechanical properties

EN 1087-1:1995 Particleboards – Determination of moisture resistance – Part 1: Boil test (this refers to OSB)

EN 594: 2011 Timber structures – Test methods – Racking strength and stiffness of timber frame wall panels

EN 596: 1995 Timber structures – Test methods – Soft body impact test of timber framed walls

Under development:

EN 14374 Timber structures – Laminated veneer lumber (LVL) – Requirements

This is being merged with EN 14279 (referenced in EN 13986) to create a universal classification for structural and non-structural LVL. This will include:

  • Specific rules for LVL with cross band veneers
  • Test methods and definitions for strength and stiffness properties
  • Strength classes
  • Tolerance modifications
  • Included for the first time – guidance on resistance to fire and fire protection ability.
