For more than 100 years, ASME (The American Society of Mechanical Engineers) standards and related product certifications have formed an interlocking system based on:

• Safety Standards:
  A set of requirements developed by volunteer technical experts using an open and transparent consensus process.
• Product Certifications:
  A program built upon the safety standards wherein the quality systems of a manufacturer are assessed and certified based on the manufacturer’s demonstrated ability to meet the requirements of an ASME standard.
• Certification Mark:
  A mark used by certified companies that is placed upon manufactured items. The symbol is designed to provide users with a high degree of confidence that the stamped items conform to established safety standards

The Standards & Certification process may involve independent, third-party inspection during the process, uniform qualification of inspectors, and acceptance by government entities. It is the common understanding and confidence and trust in this system that has enabled regulated equipment built in one jurisdiction to be readily accepted for installation in another.
