Conforming to european standards for preservative-treated timber: Specifying with confidence
2000 - IRG/WP 00-20194
A four-year collaborative study between four industrial partners and BRE has assessed timber treated by current UK industrial practices in the light of current European Standards. Data were collected for CCA and creosote treated timber components, and compared with the requirements laid out in EN351-1 and -2. A number of difficulties were encountered that have been described in previous IRG papers...

The benefits to New Zealand of boron salt treatment of Pinus radiata
1992 - IRG/WP 92-3692
The historical reasons for New Zealand adopting boric salt diffusion of Pinus radiata are summarised, and present day processes and their associated costs are given. The biological hazards of using Pinus radiata untreated are then argued, using endemic fungal and insect species as examples, as well as a discussion of the risks from species that may yet be accidentally introduced into the country....

Work programme of CEN/TC 38 (April 1999) and European publications
1999 - IRG/WP 99-20165
Scope of the CEN/TC38: Standardization of the characteristics of natural or conferred durability of wood and its derived materials against biological agents, including the characteristics of protection products and associated processes to obtain this durability. This applies in particular to: - the identification of hazard classes-, - the test methods (wood preservatives and treated wood and wood ...

The treatment of Douglas fir fence posts: specification and compliance using new European standards
1999 - IRG/WP 99-20178
New European standards for the preservative pre-treatment of timber require the results of the treatment process to be specified and subsequently verified by examination of the treated timber for penetration and retention of the preservative. For penetration, the standards are restrictive in that there are only a limited number of options available to the specifier. Thus for ground contact service...

A review of the implementation of results-based standards for preservative treated timber
1999 - IRG/WP 99-20156
European standards for the specification of preservative treated timber are written in terms of the results achieved in the commodity by the treatment process. This is described in terms of penetration and retention of preservative. Results from a study on the commercial application of this approach in the UK show the difficulties associated with applying the new European standards; particularly w...

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...

Performance based specification of wood – Introducing project CLICKdesign
2019 - IRG/WP 19-20661
This paper introduces the new ForestValue research project CLICKdesign – delivering fingertip knowledge to enable service life performance specification of wood. This European consortium is working on the primary innovation to move from the complex, fragmented and general to the easy-to-use, consolidated and specific by provision of an accessible digital tool for specifiers. Competing materials ...
