30、eement on technical cooperation between ISO and CEN (Vienna Agreement).This second edition cancels and replaces the first edition (ISO 9934-3:2002), which has been technically revised.ISO 9934 consists of the following parts under the general title Non-destructive testing Magnetic particle testing:
31、Part 1: General principles Part 2: Detection media Part 3: EquipmentDIN EN ISO 9934-3:2015-12 EN ISO 9934-3:2015 (E) 4 1 ScopeThis part of ISO 9934 describes three types of equipment for magnetic particle testing: portable or transportable equipment; fixed installations; specialized testing systems
32、for testing components on a continuous basis, comprising a series of processing stations placed in sequence to form a process line.Equipment for magnetizing, demagnetizing, illumination, measurement, and monitoring are also described.This part of ISO 9934 specifies the properties to be provided by t
33、he equipment supplier, minimum requirements for application and the method of measuring certain parameters. Where appropriate, measuring and calibration requirements and in-service checks are also specified.2 Normative referencesThe following documents, in whole or in part, are normatively reference

36、quipment design shall take into account all international, European, national and local regulations which include health, safety, electrical and environmental requirements.4 Types of devices4.1 Portable electromagnets (AC1)4.1.1 GeneralHand-held portable electromagnets (yokes) produce a magnetic fie
37、ld between the two poles. When testing according to ISO 9934-1, DC1)electromagnets should only be used if agreed at enquiry and order stages.1) AC = alternating current, and DC = rectified current.DIN EN ISO 9934-3:2015-12 EN ISO 9934-3:2015 (E) 5 Magnetization shall be determined by measuring the t
38、angential field strength, Ht, at the centre of a line joining the centres of the pole faces of the electromagnet with pole extenders where used. The electromagnet with a pole spacing, s, is placed on a steel plate as shown in Figure 1. The plate shall have the dimensions (500 25) mm (250 13) mm (10
39、0,5) mm and shall be of steel conforming to C22 (1.0402) of EN 10250-2. Periodic functional checks can be carried out either by the method described above or by a lift test. The electromagnet shall be capable of supporting a steel plate or rectangular bar conforming to C22 (1.0402) of EN 10250-2 and
40、 having a minimum mass of 4,5 kg, with the magnet poles set at their recommended spacing. The major dimension of the plate or bar shall be greater than the pole spacing, s, of the electromagnet.NOTE To lift a steel plate with a mass of 4,5 kg requires a lifting force of 44 N.Dimensions in millimetre

45、F switch, preferably mounted on the handle.Generally electromagnets should be usable with one hand.4.2 Current generators4.2.1 GeneralCurrent generators are used to supply current for magnetizing equipment. A current generator is characterized by the open circuit voltage, U0, the short circuit curre
46、nt, Ikand the rated current, Ir(RMS-values).The rated current, Ir, is defined as the maximum current for which the generator is rated at the duty cycle of 10 % and for a current “ON” time of 5 s if not otherwise specified.The open circuit voltage, U0, and the short circuit current, Ik, are derived f
47、rom the load-characteristic of the generator at maximum power (with any feedback controls disconnected). The load line of the generator can be derived by connecting two widely different loads, such as different lengths of cable, in turn to the generator. For the first cable, the current, I1, through
48、 the cable and voltage, U1, across the output terminals are measured and plotted, to give point P1on Figure 2. The process is repeated with a second load to give point P2. The load line is constructed by drawing a straight line between P1and P2. The open circuit voltage, U0, and short circuit current, Ik, are then given by the intercepts on the axes, as shown in Figure 2.DIN EN ISO 9934-3:2015-12 EN
