This International Standard defines the general principles for the application of the time-of-flight diffraction
(TOFD) technique for both detection and sizing of discontinuities in low alloyed carbon steel components. It
can also be used for other types of materials, provided the application of the TOFD technique is performed
with necessary consideration of geometry, acoustical properties of the materials, and the sensitivity of the
examination.
