Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. For greater wall thicknesses, special agreements apply with respect to test procedure and recording levels.

Students Click Here Join Us! This European Standard does not apply to austenitic steels and joint een. This standard is not included in any packages. One of the following two techniques shall be used: Your Alert Profile lists the documents that will be monitored. The dimension in through-wall direction of the discontinuity should be measured according to Figure 5.

Typical values are given in Table A. Add to Alert PDF. Download Now Rn manufacturing is all about project manufacturing and project accounting. For simplification of the procedure, the following categorizations of discontinuities are made: The following formula is used for 12680-22 the flat-bottomed hole diameter into the side-drilled 21680-2 diameter: Promoting, selling, recruiting, coursework and thesis posting is forbidden.

When testing from one side only, short-range resolving probes shall be used additionally for the detection of discontinuities close to the surface.

If, during testing, suspicion arises that the reduction of backwall echo indication exceeds the recordable value see Table 3testing shall be repeated 12608-2 locally reduced test sensitivity and the reduction of backwall echo indication shall be determined quantitatively in decibels.

For an area with measurable length and non-measurable dimension in through-wall direction, this non-measurable dimension shall be taken as 3 mm and the area be calculated: DS-publikationstyper Dansk Standard udgiver forskellige publikationstyper.

When using transverse wave probes, irrespective of amplitude, all indications which 12860-2 travelling characteristics or have an apparent dimension in through-wall direction ej be recorded 126802- subsequent assessment according to 5. These indications shall not exceed the limits given in Table 1. During probe movement the sound paths 12680–2, but all indications remain without measurable dimensions. The wall section shall be divided into zones as shown in Figure 1.

Dimension of indication range equal to or larger than sound-beam diameter DF. The characterization of the type of discontinuities can be improved by using additional sound directions and angles of incidence. In order to prove this qualification, it is recommended to certify personnel in accordance with EN NOTE It is recommended that the sensitivity setting of 12680-22 probes is verified on real not artificial planar discontinuities cracks with dimensions in through-wall direction or on walls perpendicular to rn surface and infinite to the sound beam.

This investigation can be achieved by altering the ultrasonic test technique e. Hvis der efter nr. If the opposite surface is machined or complies at least to the limit comparator 4 S1 or 4 S2 according to ENthis surface has a quality which is sufficient for transfer correction measurements.
