Collaborative soft rot tests
1981 - IRG/WP 2151
There appears to be need for reconsideration of attitudes towards Standardisation of laboratory tests for determining the toxicity of preservatives to soft rot fungi. The original approach was that a limited number of test methods were available and that collaborative effort would determine the suitability of the methods for Standardisation. It has been established so far that pure culture testing...

Draft Business Plan of CEN/TC 38 - Durability of wood and wood-based products - Introduction
2000 - IRG/WP 00-20207
CEN Technical Committees and Business Planning. The extension of formal business planning to CEN Technical Committees (CEN/TCs) is an important measure which forms part of a major review of business processes (known as 'Optimization'). The aim is to align the CEN work programme with expressed market needs and to ensure the adequate resourcing of projects through their development...

LCA applied for wooden products
1995 - IRG/WP 95-50059
This paper presents some of the international developments within ISO and SETAC to standardize and harmonize LCA methodologies. In this framework it is also important to be aware of the problems that companies have to generate and validate data for the complete product chain from cradle to grave. This concerns problems in nomenclature of substances and processes, system boundaries, allocation prob...

Practical consideration in developing an international hazard class standard: The hazards and risks
1996 - IRG/WP 96-20091
This paper discusses the concept of hazards and risks in relation to the way in which the hazard class philosophy may be used for international standardization. The difference between hazard and risk is considered as a basis for a simple classification of biological hazards for timber in use based upon its service environment. The paper proposes that the moderating influences within a service envi...

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 ...

Standardisation of sapstain tests - A challenge
1992 - IRG/WP 92-2403
In the last decade many new anti-sapstain products have been tested world-wide under laboratory and field conditions. Several extensive test programmes have been executed with different non-standardized test methods and procedures, with the result that the biological findings cannot be compared with each other. In this paper, gathered recommendations will be given in order to standardize test meth...

Wood Protection in China
2009 - IRG/WP 09-30516
The wood protection has been recognised in ancient China, and has made the tremendous contribution to the knowledge and techniques of wood protection. The paper mainly introduced the development and situation of China wood protection industry, including industry organization, policy guidance, standardization system, quality supervision, training, technical exchange, project HYPERLINK "http://dj.i...

A technique for determinging the efficacy of wood preservatives for partially treated timber
1988 - IRG/WP 2322
A technique is described for determining the efficacy of wood preservatives either for certain wood species where a full penetration cannot be achieved by normal vacuum-pressure methods or for more permeable species to look at efficacy of treated zone in preventing decay of an untreated core. Both sapwood and heartwood planks of spruce (Picea abies) and pine (Pinus sylvestris) were treated by CCA ...

Establishing standard principles for laboratory bioassays of termiticides with subterranean termites - progress, problems and prospects
1993 - IRG/WP 93-10013
Laboratory bioassays of termiticides, including wood preservatives, aim to give an indication of the likely concentrations effective in preventing damage to timber products and other materials in the field. In laboratory bioassays field conditions should be simulated as closely as possible. With a wide range of procedures in use around the world it may often be difficult to compare results between...

Standardization of preservative treated timber species for conductor, insulator and transformer packing of REB
1996 - IRG/WP 96-40071
In order to resolve the post landing failure problem of wooden packing for conductor, insulator, transformer of REB, the names of the suitable timber species from different parts of the world, irrespective of countries of origin have been standardized along with their strength and treatability grades. The CCA treatability of some Pakistani timber species have been presented for example which was t...

Standardization of CCA treated 45 hardwood species grown in Bangladesh for REB crossarms
1995 - IRG/WP 95-20059
Researches on 45 hardwood species grown in Bangladesh regarding density, moduli of rupture (MOR), colour and treatability of sapwood and heartwood, seasoning property and natural durability of heartwood revealed that both sapwood and heartwood of 17 species could be full cell pressure treated with CCA at impregnation pressure of 14-18 kg/cm² and only sapwood of rest 28 species could be pressure t...

Methodologies for termiticide testing and standardization
1993 - IRG/WP 93-10043
Standardization of testing methodologies for termiticides has been one of the main topics of discussion for Working Group 1b in recent IRG meetings. While it is agreed that there is a need to provide a standardized testing procedure for industry and regulatory agencies, concerns remain that such a standardized procedure may become an obstacle for developing better testing methods or innovations in...

Towards a unified international hazard class system
1996 - IRG/WP 96-20081
Working party 2.5 on International Standardisation has set the development of a unified hazard class system as a short-term objective. This document is intended to stimulate the discussion required to work towards such a system. Two possible approaches are discussed, the compromise approach and the development of a basic system from first principles. For the second approach, the factors impacting ...

Characterization and differentiation of wood rotting fungi by protein and enzyme patterns
1999 - IRG/WP 99-20177
Standardized tests for wood preservatives are performed with defined fungal strains to ensure comparability between laboratories. However, changes of virulence and variation of results are well known events. Suitable and reliable measures to control the stability of the test organisms are necessary.Comparison of protein patterns produced by SDS-electrophoresis was already described by several auth...
