Difficulties applying Heat Treatment according to ISPM No. 15, when fast growth species are used
2007 - IRG/WP 07-40386
In 2002, the Interim Commission on Phytosanitary Measures (ICPM) adopted the International Standard for Phytosanitary Measures (ISPM) No. 15 (Guidelines for regulating wood packaging material in international trade). Two treatments are recognized: Heat Treatment (HT), in which wood must be heated to a core temperature of 56°C for 30 minutes, and fumigation with methyl bromide. As the last treatme...

ISPM No. 15 and the Incidence of Wood Pests: Recent Findings, Policy Changes, and Current Knowledge Gaps
2011 - IRG/WP 11-30568
Largely as a result of international trade, hundreds of species of bark- and wood-infesting insects have become established in countries outside their native range. Many of these exotic insects have caused severe economic and environmental impact to urban and forest trees in the receiving countries. Most bark- and wood-infesting insects have been transported to new countries by means of the wood...

The overview of ISPM 15 implementation in Croatian wood-working companies
2011 - IRG/WP 11-30576
Croatia is a small European county, but in the same time a great country according to it’s tradition in the forestry and wood working industry. However, around 48% of it’s territory is afforested. As the export is one of the main directions in the Croatian development conception, the production and distribution of wood package intended for the international trade, is one of the most important ...

Is the SPM 15 effective? Survival of Pine Wood Nematode under thermal treatments
2017 - IRG/WP 17-40775
The pine wood nematode Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle (PWN) is the causal agent of “Pine wilt disease” affecting coniferous forests, and since its detection in 1999 in Portugal, has obligated the European Union to take action to prevent its spread (Decision 2006/133/CE). The main measure applied is the International Standard for Phytosanitary Measures ISPM No. 15 (ISPM ...

A comparison of soft rot, white rot and brown rot in CCA, CCP, CCF, CCB, TCMTB and benzalkonium chloride treated Pinus radiata IUFRO stakes, after 9-15 years exposure at five test sites in New Zealand
1991 - IRG/WP 1485
The aim of this study was to determine if decay type varies significantly between five field trial test sites of different soil type, aspect and climate in 9-15 year old, replicate CCA, CCF, CCP. CCB, TCMTB and AAC treated IUFRO stakes. A visual on-site assessment of decay type on every test stake was made and observations confirmed by microscopical examination. Regression analyses were used to de...

Risk reduction from curative treatments, restoration and maintenance of building and individual housing - simple precautions that make the difference
2005 - IRG/WP 05-50224-15
This document explores the potentialities of risk reduction, from activities of remediation in construction, developped at small scale by professionals or individuals on targets like moulds, rots, termites and other wood destroying insects, with products distributed for professional or do-it-yourself purposes. At the first stage, an inventory of the type / interest of products / processes is carri...

Management of treated wood waste in Canada - Technical and regulatory solutions
2001 - IRG/WP 01-50166-15
A major problem facing the wood preservation industry in Canada is the management of wastes. This refers to wastes generated during the treatment process as well as waste treated wood that is removed from service. The volume of oil borne preservative treated industrial products to be removed from service in Canada over the next 20 years is expected to be fairly constant at approximately 350,000 to...

Durable fibre for durable MDF – testing Tricoya®
2015 - IRG/WP 15-40704
The chemical modification of wood has been a commercial reality for a decade on release of technologies for the modification of solid wood including Accoya®. A challenge and an opportunity for the modification technologies which typically impart dimensional stability, water stability and enhanced biological durability was the adaptation of the technology to wood based panels. This paper presents ...

Variation of natural durability of sugi (Cryptomeria japonica) wood in 15 clones examined by decay test (Preliminary report)
2004 - IRG/WP 04-10526
Natural durability of wood in 27 trees from 15 clones of sugi (Cryptomeria japonica)  was investigated by an accelerated decay test. Thirty years old trees were collected from a clonal trial in Ibaraki prefecture, Japan. Natural durability is usually evaluated in heartwood. Mass losses of heartwood caused by a brown rot decay fungus, Fomitopsis palustris and a white rot decay fungus, Py...

Non leachability of arsenic, copper and chromium from 15 years old CCA-C treated southern pine poles used in brackish water as jetty piles in Bangladesh
1998 - IRG/WP 98-50103
Revealed that chromated copper arsenate type C (CCA-C) treated southern pine poles used in Central Warehouse Jetty of REB, Khulna are stable and resistant to chemical and biological attack without loss of any component from outer 0-12.5 mm zone after 15y of use. Slightly reduced retention (4.44% less) was noted in above water location of piles (bottom end of tree) which would be due to continuous ...

Evaluation of impact of CCA-treated wood on the marine environment
1995 - IRG/WP 95-50040-15
This paper reviews the literature relating to the potential of CCA-treated wood to affect the marine environment and outlines the compounds required for a model which could be used to predict the environemental impact of maritime construction using such timber. Marine pilings require high loadings of CCA to provide protection from marine borers. Though loadings of 32-48 kg/m³ provide long-term pr...

Occupational exposure risk assessment at a commercial treatment plant using copper azole preservative
1998 - IRG/WP 98-50101-15
Experience with traditional water-based preservatives such as chromated copper arsenate (CCA) applied in closed system vacuum pressure impregnation plants has shown that operator atmospheric exposure is low during normal operation. TANALITH E is a commercially available copper azole wood preservative introduced as a chrome and arsenic-free alternative to CCA based on the actives copper, tebuconaz...

Leaching of CCA from Bombax ceiba catamarans in operation for 15 years
2002 - IRG/WP 02-50191
Core samples of wood at random were collected from all the timber pieces of each of the three catamarans made of CCA treated logs of Bombax ceiba put to continuous service for the last 15 years at the Lawson's Bay fishing village, Visakhapatnam. The samples were dried to constant weight, powdered, digested and analyzed for the residual salts of the preservative. The residual content of ...
