The objective of this Interim Standard is to provide recycled timber manufacturers, suppliers and users with requirements for visually grading recycled hardwood timber intended for use in decorative applications.
For structural applications, please see the relevant interim standard here.
The Standard is an Interim Standard, as this is the first time national visual grading rules have been developed for recycled timber in Australia. It is intended that after a period of application and use, the Interim Standard will be reviewed and amended and then will be submitted to Standards Australia for consideration for development as a formal Australian Standard. In respect of the application of this Standard, statements expressed in mandatory terms in notes to tables or diagrams are deemed to be requirements of this Standard.
This industry standard applies to recycled hardwood only and sets grade descriptions for decorative recycled timber products. Recycled timber is timber that has been previously used and served its initial purpose. Recycled timber may be recovered from use for re-use either in its original size or re-manufactured to smaller dimensions.
The Standard covers products that:
- are manufactured from timber that have been sawn from larger members (eg girders, roof framing) into products such as flooring, cladding, lining, bench tops, joinery/furniture stock
- have been recovered from previous use and will be re-used without further sawing or machining (eg flooring)
- are to be lightly-loaded non structural members of larger cross section (eg decorative beams and posts).
