2006 - IRG/WP 06-20337
Because of the international approve of use class system for the biological degradation of wood by ISO/DIS 21887 and ISO/DIS 21892, Japanese committee of ISO/TC165/SC1 asked to the JWPA for classify the wooden commodities by use class of these draft ISO. The JWPA was prepared a draft use class model in Japan. Japanese building code systems are described and Japanese draft use class system is also ...

A roadmap for performance-based specification of wooden components based on service life prediction
2007 - IRG/WP 07-20351
The need for an unified and harmonised system for performance classification and specification of wood and wood-based products in Europe emanates from requirements of users and the European Construction Products Directive, CPD. A road to a feasible specification system is outlined. Exposure-related performance prediction was worked out as a key task on the way to product specification. Therefore s...

Laboratory durability testing of preservative treated wood products – first attempts and observations
2023 - IRG/WP 23-20697
In the past, durability classes (DC) had been assigned to wood species, sometimes also to homogenously modified wood-based materials such as thermally modified wood. More recently, some standards allow for classifying the biological durability of chemically modified wood, preservative treated wood and wood composites. Even treated products may be subject to durability classification, but necessary...
