The National Board of Boiler and Pressure Vessel Inspectors (NBBI) is composed of chief boiler and pressure vessel inspectors representing states, cities, and provinces enforcing pressure equipment laws and regulations. These laws and regulations represent the collective input of National Board members. [1]
The ASME Boiler & Pressure Vessel Code (BPVC) is an American Society of Mechanical Engineers (ASME) standard that regulates the design and construction of boilers and pressure vessels. [1] The document is written and maintained by volunteers chosen for their technical expertise . [ 2 ]

Boiler repair in the United States is governed by the National Board of Boiler and Pressure Vessel Inspectors and the American Society of Mechanical Engineers (ASME) under a classification called R Stamp Welding. In order to perform R Stamp welds and repairs, boilermakers are tested and certified in the quality of their weld joints through a ...
The ASME definition of a pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. [2]The Australian and New Zealand standard "AS/NZS 1200:2000 Pressure equipment" defines a pressure vessel as a vessel subject to internal or external pressure, including connected components and accessories up to the connection to external ...
The National Board of Boiler and Pressure Vessel Inspectors recommends a daily testing procedure described by the American National Standards Institute, chapter 2 part I-204.3 water level gauge.
EN 13445 was introduced in 2002 as a replacement for national pressure vessel design and construction codes and standards in the European Union and is harmonized [1] with the Pressure Equipment Directive (2014/68/EU or "PED"). New updated versions of all parts were published between 2009 and 2012.
The Pressure Equipment Directive (PED) 2014/68/EU (formerly 97/23/EC) [1] of the EU sets out the standards for the design and fabrication of pressure equipment ("pressure equipment" means steam boilers, pressure vessels, piping, safety valves and other components and assemblies subject to pressure loading) generally over one liter in volume and having a maximum pressure more than 0.5 bar gauge.
