Proposed methodology for the assessment of safety indexes
1990 - IRG/WP 3562
Safety Indexes (SI)s are developped on the same concept as Efficacy Indexes (EI)s: EIs are retentions of wood preservatives (percentages of the critical values "efficacy") which are presumed efficient for a given biological class of risk. In the same way, SIs are retentions of wood preservatives (percentages of the critical values "safety") which are taken as acceptable for human health and the ge...
Coding scheme for samples for IRG world-wide co-operative field experiment
1975 - IRG/WP 360
Each sample has been given a number containing six digits (eg 16 23 05). The first 2 digits indicate the country and person supplying the timber, the second 2 digits indicate the species of timber, and the last two digits indicate the treating concentration. All samples which end with the numbers 26 to 50 are to be placed in one site in the United Kingdom, probably at the Imperial College site at ...

Quality and safety scheme for wood in food contact
1995 - IRG/WP 95-50040-11
When there is no tolerance concerning the content in food of potential contaminants the scheme is limited to a ban of any contaminant with objectives of undetectable amounts at the limits of detection of the chemical analysis. When some tolerances exist, there is a need to check the compliance of a production to such requirements, putting in place the necessary prevention of any accidental situati...
Experiences with supervision schemes for treated timber in Denmark
1984 - IRG/WP 3315
Since 1967 a voluntary supervision scheme for vacuum-pressure treatment was established in Denmark. In 1976 the Nordic Wood Preservation Council - NWPC - established a scheme based on wood preservation classes for treated timber as a joint technical standard valid in Denmark, Finland, Norway and Sweden. This paper deals with inspection results over 17 years for CCA treatment within our organizatio...
Evaluating the performance of wood preservatives against fungi
1974 - IRG/WP 247
A compilation is made of results published by various workers for agar/block laboratory tests of the effectiveness of wood preservatives against 11 species of wood destroying Basidiomycetes and one species of soft rot fungus. Preservatives include creosote, boron, metal/arsenic mixtures, metallic naphthenates, chlorinated naphthalene, chlorinated phenols and tri-n-butyl tin oxide. The results are ...
Issues Facing Wood Preservation in Australia Today
2003 - IRG/WP 03-30327
Timber and timber products are a major part of the Australian building industry and preservative treatment is a common consideration for most timber users. Despite this however, there is a major lack of awareness by the users of the various issues associated with preservative treatment. Australian treatment specifications are logical, concise and uncomplicated. There are three agencies in Austr...
A field study on the suitability of the European lap-joint test
2001 - IRG/WP 01-20239
Within the framework of the European SM&T Research Project "Co-normative research on field tests for wood preservatives out of ground contact in conjunction with methods for preconditioning test specimens prior to test" (FACT) one aim was to establish the suitability of the European lap-joint test (as it is described in ENV 12037:1996) to assess wood preservatives in the field in EHC 3. Scots ...

IRG/COIPM INTERNATIONAL MARINE TEST - To determine the effect of timber substrate on the efectiveness of different preservatives in sea-water: Coding scheme
1976 - IRG/WP 420
It was agreed in Wildhaus on 15 May 1976 that preparations for the test detailed in Document No: IRG/WP/414 should commence immediately, but that initially only two water-borne preservatives should be used - a copper/chrome/arsenic (CCA) and a copper/chrome/boron (CCB) formulation respectively. PRL, England (R Cockcroft) would be responsible for supplying only the reference species treated with th...
