American Society of Mechanical Engineers 

ASMEAmerican Society of Mechanical Engineers was founded in 1880. It is the American equivalent of the UK's Institute of Mechanical Engineers. Today's ASME promotes the art, science and practice of mechanical and multidisciplinary engineering and allied sciences around the globe. It has an influence on NDT through the ASME Boiler and Pressure Vessel code. A code is a standard that has been adopted by one or more (American) governmental bodies and has the force of law.

The ASME BPV is 28 volumes containing the necessary information for material specifications, rules for construction, fabrication and inspection of boilers and pressure vessels, including nuclear components. The requirements for inspections are given within the code but there are two main sections which are of particular relevance NDT.

Section V: Nondestructive Examination – this section gives details on all the NDE methods and has recently added an article, Article 14 Examination System Qualification, which gives information on qualifying inspection systems including information on the calculation of PoDs.

Section XI: Rules for Inservice Inspection of Nuclear Power Plant Components – this section gives requirements for the ISI of components on nuclear plant which are operated in accordance with the ASME code.
