ASME Codes and Standards
ASME is one of the oldest standards-developing organizations in America. It produces approximately 600 codes and standards covering many technical areas, such as fasteners, plumbing fixtures, elevators, pipelines, and power plant systems and components. ASME’s standards are developed by committees of subject matter experts using an open, consensus-based process. Many ASME standards are cited by government agencies as tools to meet their regulatory objectives. ASME’s standards are used in more than 100 countries and have been translated into numerous languages.

Authorized repair organizations are issued symbol stamps for application to equipment nameplates signifying the integrity of work performed.
