U.S. DOT Conversion to ISO Standards U.S. DOT Conversion to ISO Standards ironcaster (Industrial) (OP) 13 Aug 02 06:54 I am looking for information about the U.S. DOT conversion to ISO Standards. I know the status of the FAA and the U.S. Coast Guard. I am more interested in Ground Transportation issues. RE: U.S. DOT Conversion to ISO Standards namdac (Civil/Environmental) 12 Oct 04 14:06 The only standards that are available are at the individual state level. i.e. All D.O.T. have standards on their respective web sites.
