ENNon-destructive testing — Ultrasonic examination — Part 1: This European 122680-2 applies to the ultrasonic examination of steel castings which have usually received a grain refining heat treatment and which have wall thicknesses up to and including mm. Denne publikations overensstemmelse er: Figure 4 — Recording and acceptance limits for volumetric indications with measurable dimensions in the core zone see also Figures C.
This standard is not included in any packages. Please first verify your email before subscribing to alerts. Subscription pricing is determined by: The maximum distance between discontinuities as criterion for evaluation as an individual indication in through-wall direction or lateral to the surface, 12680-22 be 10 mm. You may delete a document from your Alert Profile at any time.
Dimension of indication range equal to or larger than sound-beam diameter DF. NOTE 2 Annex C gives information on types of indications and on the determination of their dimensions.

When can I know if one 126680-2 is higly stressed or not? It’s easy to join and it’s free. This investigation can be achieved by altering the ultrasonic test technique e.
These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. This type of indication should only be evaluated if, due to geometrical reasons, a back-wall echo cannot be obtained. Already Subscribed to this document. Annexes B and C are informative. ENNon-destructive testing — Characterization and verification of ultrasonic examination equipment — Part 3: For wall thicknesses greater than mm, agreement shall be made between the parties concerned on the test procedure and also on the recording and acceptance levels.
For the identification of the type of indication, the test sensitivities can be changed according to: Unless other requirements have been agreed by the time of acceptance of the order, for finishing welds, the requirements for the parent metal shall apply. The same coupling medium shall be used for calibration and all subsequent examination operations. Defense manufacturing is all about project manufacturing and project accounting. Download Now Defense manufacturing is all about project manufacturing and project accounting.
In special cases, specific agreements can be made. A simultaneous reduction of backwall echo should be evaluated in accordance with Figure C. The sound transmission can be checked by ensuring one or sn stable backwall echoes in areas with parallel 5. The location of reflection points shall be documented, e.
Figure 3 — Recording and acceptance limits for volumetric indications with measurable dimensions in the rim zone see also Figures C. Group of indications, mainly non-resolvable individual indication.
The maximum distance between discontinuities as criterion for evaluation as an 1680-2 indication in through-wall direction or lateral to the surface, shall be 20 mm.
