Proof Testing to AS1720 App. D
Proof Testing to AS1720 App. D
(OP)
Has anyone specified timber elements to be proof tested as per AS1720 App. D?
I have existing trusses which are to be re-used and I don't know the stress grade amongst other things. Does anyone know of an acceptable means to establish the stress grade on-site.
If the trusses can be proof tested, what needs to occur for the proof testing to occur. Does the testing need to be performed by a person with some sort of accreditation?

There are qualified graders out there, visual grading is done to AS2082 or AS2858 (hardwood and softwood respectively).
