Keeping plywood up to standard
Getting together at Plywood House in Brisbane for deliberations on a number of plywood standards are, seated from left, Kevin Lyngcoln (chairman), Simon Dorries, general manager, Engineered Wood Products Association of Australasia, Andrew Powell, Timber Development Association (NSW), and Warwick Banks (observer), and standing, Ch-nam Si, Standards Australia, John Barber, New Zealand Wood Processors Association, Doug Gaunt, Scion New Zealand, Sharon Adlam, Building Products Innovation Council, and Graeme Beattie, BRANZ New Zealand.
The revision of the standards, funded by Forest and Wood Products Australia, assures they are consistent with the latest version of AS1720.1 – Timber Structures Code; “The updates will ensure plywood can continue to be used in all building applications governed by the Building Code of Australia,” Simon Dorries said.
“The funding by FWPA is greatly appreciated by industry.”
Mr Dorries said extensive revisions of LVL standards would take place in 2012.
Stakeholders at a meeting of the TM006 committee in Melbourne recently addressed changes required to the AS/NZS 1604 series.
The 5-part standard covers solid sawn and round wood (part 1), as well as engineered products like various wood-based panels (part 2), plywood (part 3), LVL (part 4), and glulam (part 5).
[Only part 1 (sawn and rounds) is an Australian product; the other four parts are joint Australia/New Zealand standards]. The AS/NZS 1604 series was extensively revised and published in 2010, but since that time there have been significant changes to biocides, formulations (e.g. carrier system) and product manufacturing (e.g. veneer thickness, application of biocide to veneer surfaces), in addition to the gluelines and/or the veneers themselves.
There were also a number of operational-type changes such as the route to introducing preservatives to the standard, clarification of branding requirements, and the designation of some new preservative numbers.
“Taken together, these changes were sufficient in numbers and significance to warrant another revision of the five parts of the standard,” committee chairman Dr Harry Greaves said.
Key industry bodies at the Melbourne meeting included the Australian Forest Products Association, APVMA, Australian Timber Importers Federation, DEEDI, Engineered Wood Products Association of Australasia, Forests NSW, Glued Laminated Timber Association of Australia, Monash University, NZ Pine Manufacturers Association, Responsible Care New Zealand, NZ Timber Industry Federation, Timber Preservers Association of Australia, Timber Queensland / FWPA, and the Wood Processors Association NZ.
The Engineered Wood Products Association of Australasia provides accreditation for plywood, LVL, particleboard, MDF and solid timber.Learn more
