Info

An important source of practice codes, standards, and recommendations for NDT is given in the Annual Book of the American Society of <strong>Testing</strong> and Materials, ASTM. Volume 03.03, Nondestructive <strong>Testing</strong> is revised annually, covering acoustic emission, eddy current, leak testing, liquid penetrant, magnetic particle, radiography, thermography, and ultrasonics. There are many efforts on the part of the National Institute of Standards and Technology (NIST) and other standards organizations, both national and international, to work through technical issues and harmonize national and international standards.
Reference Reflectors: are used as a basis for establishing system performance and sensitivity.
