Certification/Standard: American Society of Mechanical Engineers (ASME)
Category: Certification: Quality management
Type: Third-party certification
ASME codes and standards cover engineering disciplines ranging from hand tool and elevator to bioprocess equipment manufacture. ASME standards provide guidelines, procedures, and recommended practices for designing, operating, maintaining, and testing equipment and systems.
ASME and the American Welding Society (AWS) work together to develop welding standards. The main difference is that addresses fabrication, erection, inspection, and welder and welding procedure qualification, whereas ASME covers welder and welding procedure qualification. Generally, certification to both standards is acceptable. If a job involves pressure vessels or piping, however, the ASME boiler and pressure vessel code must be followed.
ASME offers four types of product certification programs:
ASME certification is relevant to the pressure vessel industry, including: nuclear vessels, pumps, valves, transport packaging and concrete containers; thermoset plastic (RTP) vessels; and welding materials such as electrodes, wires, flux, and filler metal.
It is estimated that over 100 countries accept the ASME boiler and pressure vessel code as a means of meeting their government safety regulations. ASME currently has over 6,000 certified companies in more than 70 nations around the world.
