Try contacting http://www.timberframes.com.au/ to see who or how they get their structural wood certified, they are based in the Adelaide Hills.

I think if it is structurally sound, you know roughly what species it is and the dimensions, then you can pretty much grade it yourself and work out if it is suitable to do what you want. I have used a lot of recycled timber in my place and the building inspector has no issue with it.

Talk to your building inspector - he is the one that passes/fails it in the end.

We recently used some new ungraded cypress where our plans specified F7 oregon. I just made sure that it was nice straight grained timber and slightly over sized. Building inspector was happy.

With a previous building experience F8 hardwood was specified. We used recycled hardwood and once again inspector happy - said if the timber was graded it was likely to have been at least F32.

I reckon if you are using recycled timber it should be well seasoned (unless it has rot from being outdoors) so stronger than new stuff and 'reasonable' building inspectors would be happy for you to use it.

If your inspector is a worrier, you could offer to use larger sized timbers than specified in your plans (discuss this with your building designer / architect / draftsman as they will have span tables..and know what else it could impact).
