Still under development:

The original plan to amalgamate two LVL standards is still unresolved.  The two standards are EN 14374 (structural LVL) and EN 14279 LVL: Definitions, classification and specification and include guidance on resistance to fire and fire protection ability.

18 standards are currently under review:
