WHAT DO THE ALPHA-NUMERIC DESIGNATIONS MEAN?
The capital letters S, EP, D, and X designate the document classifications of Standard, Engineering Practice, Data, and Project, respectively. The capital letter, T, after the numeric designation indicates Tentative classification. The base 3-digit number has no significance other than to identify the standard. The base number was assigned when development of the standard began as an ASABE project. The digit following the decimal identifies a specific technical revision of the original document. The date after the document number indicates the most recent action on the document (adoption, revision, or reaffirmation).
