Early use of editions not yet declared in force is permitted, unless specifically prohibited by the Administrator.

In 2015, government enabled timely code adoption in the Pressure Equipment Safety Regulation. This means new codes and standards editions adopted under the PESR will come into force automatically one year after publication. It also means that the regulation will no longer be updated as new code editions come into force. This page will provide industry with which codes and standards editions are in force.
