EWPAA members manufacture standardised engineered wood products to Australian and New Zealand Standards under the EWPAA product certification scheme:
 |
AS/NZS 2269:2008 Structural Plywood. Note This standard has been divided into 3 sub parts
 |
2269.0 is the specifications for structural plywood |
|
2269.1 is the test methods for structural plywood |
|
2269.2 is the evaluation of structural properties for structural plywood |
|
|
AS/NZS 2270:2006 Plywood and Blockboard for Interior Use |
|
AS/NZS 2271:2004 Plywood and Blockboard for Exterior Use (with 2006 Amendment) |
|
AS/NZS 2272:2006 Plywood - Marine |
|
AS/NZS 4357:2005 Structural Laminated Veneer Lumber, which has 5 sub parts :
|
4357.0:2005 Specifications (Revision of Existing AS/NZS4357.0) |
|
4357.1:2005 Methods of Test for measurement of dimensions and shape |
|
4357.2:2006 Determination of structural properties - Test methods |
|
4357.3:2006 Determination of structural properties – Evaluation |
|
4357.4:2005 Determination of formaldehyde emissions |
|
|
AS 6669 Formwork Plywood |
The following standards are used in relation to sampling and testing:
|
AS/NZS 2097:1998 Methods of Sampling Veneer Plywood
|
|
AS/NZS 2098:Parts 1-8 2006, and Part 9 1995 and Part 11 2005 Methods of Test for Veneer and Plywood |
|
AS 2754.1: 1985 Adhesives for Plywood Manufacture |
|
AS/NZS 4357 Parts 1 and 4 2005, Parts 2 and 3 2006 Structural Laminated Veneer Lumber |
The following standards are also applicable to plywood and Laminated Veneer Lumber (LVL):
|
AS 1684 : Part 1 1999 and parts 2, 3 and 4 2006 Residential Timber-Framed Construction Code
-
details the application of structural plywood in residential flooring and structural wall bracing applications.
The Standard also covers the application of structural plywood in residential roofing applications.
|
|
AS 1720.1 : 1997 with amendments 1 to 4 Timber Structures Code
-
provides details for the use of plywood and LVL in engineered timber structures. The code contains the design
methodology for both plywood and LVL as well as information on the design capacity of various fastener types. Structural plywood is the only wood based panel product specified in the code. Characteristic strengths and moduli of elasticity and rigidity are given for eight stress grades of structural plywood. This code is important for all designers, architects and engineers involved with timber structures.
|
|
AS 3610 : 1995 with amendment 1 Formwork for Concrete - provides details of the application of plywood in concrete formwork |
|
AS/NZS 1604.3 and AS/NZS 1604.4 Specification for preservative treatment
Part 3 : Plywood, Part 4 : LVL, both issued in 2004 with amendments in July 2006 and March 2008 |
The following standards are being reviewed in regard to the development of a testing and evaluation standard specific to LVL:
- AS/NZS4063 – Structural Products – Strength & Stiffness Evaluation
- ASTM5456 – Evaluation of Structural Composite Lumber
- ASTM D198 – Static Tests of Lumber in Structural Sizes
- ASTM D143 – Shear Test Method Only
- PrEN 408 – Structural Timber and Glue Laminated Timber – Determination of some physical and mechanical properties
- Research Paper – Characteristic Shear Strength Values based on Tests according to EN 1193
- EN1058 – Determination of Characteristic values of mechanical properties and density
