Mr. Damien Owens:

It is important that we get it right. The existing standard was adequate for what it was designed to do. Since we have started taking samples and engineers have compiled reports, however, other mechanisms of deterioration have become visible. In this instance, when we are dealing with uncertainty, the standard becomes less reliable shall we say. If an interim standard is issued or there is an interim statement it would be most welcome. We welcome anything that can provide clarity as we move forward.
