ASME is built with the most modern web standards, which give you a better & more reliable experience.
The ASME PRD Laboratory Accreditation Program covers laboratories that perform capacity certification tests of pressure relief valves manufactured in accordance with the ASME Boiler & Pressure Vessel Code.
Laboratories must also comply with the ASME PTC 25 standard for pressure relief devices. This Code provides standards for conducting and reporting tests on reclosing and non-reclosing pressure relief devices in boilers, pressure vessels, and related piping equipment.
Engineers make up ASME, and it's that passion and knowledge that literally runs the world.
By volunteering you can learn new skills, help the world, and influence the ASME of tomorrow.
