Errata are limited to discrepancies between the balloted and published version of the standard and typographical errors in the published version of the standard. Errata are approved by the Chair and need not be processed as a proposed revision in accordance with these Rules.
Supplements require balloting by the consensus body (standards committee), a public comment period, and approval of the process by the appropriate institute standards council and the ASCE Codes and Standards Committee.
Supplements and errata are posted with the Standard record
in the ASCE Library: ASCE Standards.
