Studies on the resistance of wood/wood products to wood-destroying organisms including its durability classification

Changes in the legal situation and the emergence of new materials require valid information on biological resistance in order to optimally use wood and wood products according to their durability.

Background and Objective

Wood has been used as a building material for centuries. However, it is also known that wood as a renewable raw material can be degraded by wood-destroying organisms depending on the conditions of use (EN 335). In order to counteract this natural process and to guarantee the longest possible service life of the timber construction, various measures, which are often standardised (e.g. EN 350, EN 15228 or DIN 68800), are used to protect timber.
Within the framework of pre-normative research, we are therefore continuously concerned with their application for the purpose of determining characteristic data of wood and wood products. At the same time, these methods must be further developed, as modified woods are increasingly being offered on the market.
Our aim is to make a contribution to ensuring product quality during the service life of wood and wood-based materials while using as little wood preservative as possible.


Target Group

Approval bodies, standardization bodies, construction industry, consumers

Approach
