Resumen: 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.Although it is applicable, in general terms, to discontinuities in materials and applications covered by ISO 16810, it contains references to the application on welds. This approach has been chosen for reasons of clarity as to the ultrasonic probe positions and directions of scanning.Unless otherwise specified in the referencing documents, the minimum requirements of this International Standard are applicable.Unless explicitly stated otherwise, this International Standard is applicable to the following product classes as defined in ISO 16811:- class 1, without restrictions;- classes 2 and 3, specified restrictions apply.NOTE 1 See Clause 9.The inspection of products of classes 4 and 5 requires special procedures, which are also addressed.NOTE 2 See Clause 9.NOTE 3 Techniques for the use of TOFD for weld inspection are described in ISO 10863.NOTE 4 The related acceptance criteria are given in ISO 15626.
