Corrosion of fasteners in treated wood
1971 - IRG/WP 303
Surveying tests for determining the corrosion rates of some metals and alloys in wood untreated as well as treated have been made. It is shown that ordinary steel corrodes faster than other common fastener metals such as copper, brass, aluminium and stainless steel do. Zinc coatings, however, will prevent the steel corrosion effectively provided that the coatings are thick sufficiently. Catalytic ...

Controlling marine borer attack of timber piles with plastic wraps
1981 - IRG/WP 479
Plastic films 20 to 40 mils thick have been used for many years to wrap creosoted timber piles in service to protect them from attack by marine borers. As long as the wrap remains undamaged, this procedure provides complete protection to the pile. Properly applied, wraps generally provide protection for 25 yeara or longer. Polyvinyl chloride (PVC) and polyethylene (PE) films are specially formulat...

Overview of European discussions on Standardisation and list of proposed standards for WPC performance qualification
2006 - IRG/WP 06-20345
The standardisation is a driving force to promote the development of Wood Polymer Composites (WPC) by giving confidence to users and consumers. In Europe, the high interest of WPC require at this time a diffusion of information concerning the performances of WPC products. The WPC performances must be assessed according relevant standards in order to qualify the intrinsic properties of WPC (mechani...
