BS DD ENV 583-6:2000 Non-destructive testing - Ultrasonic examination - Time-of-flight diffraction technique as a method for detection and sizing of discontinuities
This European hestandard defines the general
principles for the application of the Timeof-flight
diffracton ('T0FD) technique for both detection and
sizing of discontinuities in low alloyed carbon steel
components. It could also be used for other types of
materials, provided the application of the TOFD
technique is performed with necessary consideration of
geomeixy, acoustical properties of the materials and the
sensitivity of the examinati on
Although it is applicable, in general terms, to
discontinuities in materials and applications covered by
EN 583-1, it contallis references to the application on
welds. This approach has been chosen for reasons of
clarity as to the ultmsonic probe positions and
directions of scanning.
Unless otherwise specified in the referencing
documents, the minimum requirements of this
hestandard are applicable.
Unless explicitly stated otherwise, this hestandard is
applicable to the following product classes as defined
in EN 583-2
- class 1, without restrictions;
- classes 2 and 3, restrictions will apply as stated in
clause 9.
The inspection of products of classes 4 and 5 wiil
require special procedures. These are addressed in
clause 9 as well.
