DESCRIPTION

BS EN 351-1:2023 - TC


This standard BS EN 351-1:2023 - TC Tracked Changes. Durability of wood and wood-based products. Preservative-treated solid wood is classified in these ICS categories:
  • 79.040 Wood, sawlogs and sawn timber
  • 71.100.50 Wood-protecting chemicals
This part of EN 351 establishes a classification of preservative-treated wood in terms of preservative penetration and gives guidance on a classification of retention. These shall be used as a basis for specifying preservative treatments for particular products. This part of EN 351 provides terminology to be used by the specifier when preparing a preservative treatment specification or product standard. It is not a treatment specification in itself. This part of EN 351 is applicable to the production of preservative-treated solid wood, including glued laminated timber, suitable for use in those service conditions defined by the use classes in EN 335. It does not apply to any subsequent examination of treated wood in service. This part of EN 351 is applicable to the protection of wood against attack by wood-destroying and wood-disfiguring fungi, insects and marine organisms. NOTE Protection against wood-disfiguring fungi is an optional property verified by testing in accordance with EN 599-1. This part of EN 351 does not consider other properties of treated wood, for example odour, compatibility with other materials, such as corrosivity of fasteners. Nor does it consider any properties from the health, safety and environmental point of view. This part of EN 351 does not apply to wood to be treated with formulations which are applied to timber in service to eliminate or control an existing fungal or insect infestation, or the prevention of attack by sapstain fungi, or insects in green timber. Annex A (informatives) provides a decision process for defining preservative treatment requirements. Annex B (informative) gives an example of the marking system.
