As specified in MIL-STD-1840, files of IGES data for interchange shall begin with a data block containing header records that characterize the IGES information. The header record data block shall be present in all data interchanges regardless of the physical media or transfer mechanism used. The MIL-STD-1840 "dtype" data header record specifies the IGES subset or protocol and shall have permissible values of 1, 2, 3, 4, or 5. This value shall be 1 to indicate Class I, 2 to indicate Class II, 3 to indicate Class III, 4 to indicate Class IV, or 5 to indicate Class V. AMSC N/A AREA IPSC DISTRIBUTION STATEMENT A.
