Biological durability of wood and wood-based products – Testing the efficacy of wood preservatives against the attack by marine organisms - Part 1: Screening laboratory test for European Limnoria species CEN/TS 18327-1:2026

Publication date:   Jun 18, 2026

Scope

This document describes a laboratory method of testing which gives a basis for the assessment of the efficacy of a wood preservative against Limnoria species of European limnoriids.
This document allows the determination of the concentration at which the wood preservative prevents the attack of impregnated wood of a susceptible species by these crustaceans.
The described laboratory method can also be adapted to determine the value of inherent (natural) or enhanced (modified) biological durability of a given wood species, wood quality, or wood-based material against the attack by these crustaceans. In this case Annex C describes alterations of this document accordingly.
NOTE This method can be used in conjunction with an ageing procedure.
