The ASME Codes do not automatically adopt newly revised referenced standards (ie ASTM, API). Each revised Std have to be reviewed individually to ensure their content is still appropriate. This is a laborious task among Code Committee Members and is done between Code Meetings.
If you are interested in becoming apart of this process, attend any ASME BPV or Piping Code meeting. Vistors are welcomed to attend. A schedule of future meetings are perodicall posted in Mechanical Engineering Magazine.
