Does anyone know what guidelines are used by engineers/RTA in NSW for installation of hard brake lines to a vehicle?

what type of clamps etc are acceptable, can they run against underbody, or need to be suspended away?

I've learned one from scott @ mad dat, that lines must not be in contact with metal surfaces, due to risk of vibration wearing a hole in line.
E.g. line that runs across front x member, i've used 6mm p clamps to support away from metal.

any comments or directions to specific pages on net would be of great help.

Thanks
