25、.1test objectpart to be tested3.2test surfaceareas of the surface of the test object to which probes have to be coupled4 Ultrasonic test system4.1 GeneralThe ultrasonic pulse-echo technique is used. For two-dimensional discontinuities parallel to the test surface and three-dimensional discontinuitie
26、s, straight beam probes (dual-element or single-element) shall be used for testing with longitudinal waves.4DIN EN ISO 17405:2014-10 EN ISO 17405:2014 (E) For discontinuities with any other orientation, dual-element angle-beam probes for longitudinal waves can be used.The nominal frequency shall be
27、selected according to the purpose of the test and the characteristics of the materials.Frequencies from 2 MHz to 6 MHz should be preferred.The instrument used shall comply with the requirements given in EN 12668-1, and the probes shall comply with the requirements of EN 12668-2The whole test system
28、shall be checked by the operator periodically as given in EN 12668-3.4.2 Requirements regarding probes4.2.1 Single-element straight beam probes for longitudinal wavesA depth zone providing optimum sensitivity is defined (see Annex A) by the size of the transducer used in the probes. The position of
29、this zone should be selected according to the expected position of the discontinuities.4.2.2 Dual-element straight-beam probes for longitudinal wavesA depth zone providing optimum sensitivity is defined (see Annex A) by the size of the transducers used in the probes and their roof angle. The positio
30、n of this zone should be selected according to the expected position of the discontinuities.4.2.3 Dual-element angle-beam probes for longitudinal wavesThe beam angle should be between 65 and 80. The skewing angle, and the shape and size of the transducers, shall be selected so that the depth range f
31、or optimum sensitivity (see Annex A) covers the expected position of the discontinuities.4.2.4 Matching probes to curved surfacesThe distance between the surface and the contact surface of the probe shall not exceed 0,5 mm when the centre of the probe is in contact. To achieve this, a flat probe sha
32、ll be matched to the curvature of the test object by grinding, using adaptors or other aids if the radius of curvature, R, is within the rangeRA4 dB Setting shall be corrected and all testing carried out with the equipment over the previous period shall be repeated.3 Increase in sensitivity 4 dB Set
33、ting shall be corrected and all recorded indications shall be re-examined.Range1 Deviations 2 % of the range Setting shall be corrected before testing is continued.2 Deviations 2 % of the range Setting shall be corrected and testing carried out with the equip-ment over the previous period shall be r
34、epeated.6.4 Recording levelsUnless the conditions of delivery or acceptance stipulate the recording levels, it is recommended to use the echo heights of the reference reflectors specified in Clause 4 as recording levels.The recording level for discontinuities oriented perpendicularly to the surface
35、shall be agreed upon for each case separately. A possible choice for the recording level in such a case is given in Annex A.7 Test reportThe test report shall give the following information for each test:a) a reference to this International Standard (i.e. ISO 17405:2014);b) general information on te

38、:1) positions of detected discontinuities in a reproducible coordinate system specified for the test object;2) depth position and echo height of discontinuities (referred to the echo height of the reference reflector) of any signals to be recorded;3) lengths and widths of discontinuities to be recor
39、ded using the 6 dB-drop technique;4) typical indications that cannot be avoided during the test (e.g. because of the surface condition or the dimensions of the test object).12DIN EN ISO 17405:2014-10 EN ISO 17405:2014 (E) Annex A (informative) Determination of focal zoneIf it is not specified by the
40、 manufacturer of the probe, the depth range giving optimum test sensitivity, the so-called focal zone, can be determined for dual-element straight beam probes with a reference block with flat-bottomed holes, which can also be used for the location of discontinuities as described in 4.4.1.Figure 1 sh
41、ows the probe and the recommended reference block for flat surfaces. The height of the echo from the various flat-bottomed holes can be plotted in a diagram against depth. From this, both the focal distance and the focal zone can be read off. The points at which the echo height has dropped by 6 dB a
42、re used for determining the focal zone. If the focal zone has not been specified by the manufacturer with dual-element angle-beam probes, a reference block as shown in Figure 2 with side-drilled holes parallel to the surface and perpendicular to the probe axis can be used. The echoes of the side-dri
43、lled holes at various depths can be used for determining the focal distance and also the focal zone.If the probes have to be matched to the curvature of the surface and the position of the focal zone has to be known for the test, it shall be determined on reference blocks as shown in Figure 1 or Fig
44、ure 2 with a surface of similar curvature.13DIN EN ISO 17405:2014-10EN ISO 17405:2014 (E)Bibliography1 ISO 7963, Non-destructive testing Ultrasonic testing Specification for calibration block No. 22 EN 1330-2, Non-destructive testing Terminology Part 2: Terms common to the non-destructive testing methods14DIN EN ISO 17405:2014-10 EN ISO 17405:2014 (E)
