NOCSAE Document Numbering
Each NOCSAE document (ND) has a unique document number (NDXXX). After the document number there is a hyphen and further notation (NDXXX-YYmZZ) to mark the year the document was last revised (YY). The year following the “m” is the year the document was last modified (ZZ or ZZa, etc.). For example document number ND001-17m23 was last revised in 2017 and it was last modified in 2023.
