All such standards are developed by a consensus standards process managed by the ASCE Codes and Standards Co

15、mmittee (CSC). The consensus process includes balloting by a balanced standards committee and reviewing during a public comment period. All standards are updated or reaf rmed by the same process every ve to ten years. Requests for formal interpreta- tions shall be processed in accordance with Sectio

16、n 7 of ASCE Rules for Standards Committees, which are available at www.asce.org.
