Answer from Randy: What type of standards, locking, thickness, etc. I am not aware of any.
Answer from Andy: That's the thing about the security requirements - most banks are doing more than the minimum now so the standards are rarely enhanced in an attempt to keep up with technology because banks are far ahead already. Banks do more for their own protection, personnel, and to save on insurance and the like. As to the integrity of the doors, why would you set the predominant door superior to others? That just makes the others the "weaker link" and the target for a robbery. Those doors are likely less visible and that worsens this scenario.
