ASME has been setting the standard in personnel certification for over two decades. Acting by request of federal agencies, ASME provides particular industries with a uniform standard for evaluating professional competency. ASME certification is the clearest way to tell customers, supply chain, industry, and regulators that your company is committed to public safety and quality. Over 100 countries accept the ASME BPVC to meet government safety regulations.
The NB mark is used by manufacturers to identify items registered with the National Board. It is also used by pressure relief device manufacturers and assemblers to identify pressure relief devices that have been certified by the National Board.
This acceptance and certification is symbolized by the “U Stamp” for pressure vessels. The U Code Symbol on a vessel is used to confirm that the stamped item is in conformance to the latest edition of the Code and that the pressure vessel has been designed and manufactured in accordance with ASME.
The National Board offers the Certificate of Authorization and R symbol stamp for the repair and/or alteration of boilers, pressure vessels, and other pressure-retaining items.
