To identify the type of indication, the test sensitivity can be changed according to the distance from the test surface, the geometrical shape and the surface finish of the test surface. Clustering of indications, mainly resolvable with non-measurable dimensions. ENNon-destructive testing — Ultrasonic examination — Part 2: Download Now White Paper: By 1268-2 you are opting in to receive e-mail. The maximum distance between discontinuities as criterion for evaluation as an individual indication in through-wall direction or lateral to the surface, shall be 10 mm.

For simplification of the procedure, the following categorizations of discontinuities are made: This European Standard 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. For greater wall thicknesses, special agreements apply with respect to test procedure and recording levels.

The height of the echo indication is given as flat-bottomed or side-drilled hole diameter. This type of indication should only be evaluated if, due to geometrical reasons, a back-wall echo cannot be obtained.

This standard is not included in any packages. The severity level for special rim zones shall be specified by the purchaser.

The characterization of the type of discontinuities can be improved by using additional sound directions and angles of incidence. This European Standard specifies the requirements for the ultrasonic examination of steel castings with ferritic structure for highly stressed components and the methods for determining internal discontinuities by the pulse echo technique.

Testing with twin-crystal probes is only adequate for wall thicknesses up to 1268-02 mm. Standards Subsctiption may be the perfect solution. Proceed to Checkout Continue Shopping.

It’s easy to join and it’s free. Individual indication smainly in the same position in through-wall direction. Individual indications with measurable dimensions mainly in the through-wall direction: Individual echo with pronounced echo dynamics only in through-wall direction travelling indicationor both in through-wall direction and parallel to the test surface: The same coupling medium shall be used for calibration and all subsequent examination operations.

Typical values are given in Table A.
