BS EN 16392-2:2014EN 16392-2:2014 (E) 4 1 Scope This European Standard covers linear phased array probes used for ultrasonic non-destructive testing in contact technique (with or with
17、out a wedge) or in immersion technique, with centre frequencies in the range 0,5 MHz 10 MHz. This European Standard specifies the characterisation tests that have to be done at the end of the fabrication of a phased array probe. It defines both methodology and acceptance criteria. This document does
18、 not describe methods and acceptance criteria to characterise the performance of an ultrasonic phased array instrument or the performance of a combined system. These are described in prEN ISO 18563-1 and in prEN ISO 18563-3. 2 Normative references The following documents, in whole or in part, are no

35、 periodically. Testing shall be carried out with the probe cables and matching devices specified on the probe data sheet. In addition to the ultrasonic phased array instrumentation or laboratory pulser-receiver, the following equipment or its equivalent is essential to test phased array probes in ac
36、cordance with this document: a) an oscilloscope with a minimum bandwidth of 100 MHz; b) a frequency spectrum analyser with a minimum bandwidth of 100 MHz, or an oscilloscope/digitiser performing Fast Fourier Transform (FFT). 6.2 Tests block and other equipment Phased array probes can be used in cont

Depending on this, the performance tests shall be carried out under corresponding conditions: a) Contact technique with wedge (integrated or not integrated); A block of the same material as the wedge and proper dimensions so that the
38、 total ultrasonic path is the same for each element shall be used; If the wedge can be removed, the test shall preferably be performed without the wedge. b) Contact technique without wedge; A block of the material to be tested shall be used so that the total ultrasonic path is the same for each elem
39、ent. If no material is specified a block of steel grade according to EN ISO 2400 shall be used. c) Immersion technique. Performance tests shall be carried out in immersion fluid using a defined reflector at a specified distance, which has to be reported in the data sheet. If no fluid is specified wa

42、 and for physical damage. For contact probes measure the flatness of the contact surface of the probe. 7.2.2 Acceptance criterion For flat faced probes, over the whole probe face the gap shall not be larger than 0,05 mm. 7.3 Frequency, bandwidth and pulse duration 7.3.1 General Measurements shall be
43、 done on each element of the probe. 7.3.2 Method Measurements are performed in transmit-receive mode according to 6.2. The transmitter pulse shall be a negative square pulse, the duration of which is equal to half the period corresponding to the nominal probe frequency. The echo of the reflector sha
44、ll be placed in a time window, the duration of which is at least twice the duration of the echo pulse measured at -20 dB of the signal amplitude. The frequency spectrum shall be determined on the signal in the used time window. The frequencies intersecting the spectrum at -6 dB of the maximum amplit
45、ude of the spectrum shall be determined. From the upper and lower frequencies thus obtained, respectively named, fu, and, fl, the centre frequency ,f0, is calculated as follows: 2lu0fff+= (1) the bandwidth is defined as follows: lufff = (2) And the relative bandwidth is calculated in %, as: ( ) 100
46、/ 0rel= fff (3) 7.3.3 Acceptance criteria Values obtained for the frequency, bandwidth and pulse duration, are the values for each element. The centre frequency shall be within 10 % of the frequency stated in the data sheet. The -6 dB bandwidth shall be equal to or larger than the bandwidth stated i
47、n the data sheet. The pulse duration shall be smaller or equal to the value stated in the data sheet.
