Get out of jail cards (Statement of work authorizing access, was Re: Pentester convicted..)

I'd be very much interested in whether there is a consensus
document used by those performing vulnerability assessments
that specifically authorizes pen testing which is sufficiently
robust to protect the consultant from civil and criminal
action.

Would anyone care to share, comment, etc.?  Thanks in advance.
