4 1 Scope This European Standard defines the general principles of the measurement of the magnetic properties of electrical sheets and strips by means of a single sheet tester and gives the technical details of the measurement of specific total loss and of magnetic field strength, excitation current and specific apparent power. This European Standard is applicable at power frequencies to : a) grain oriented magnetic sheet and strip :  for the measurement between 1,0 T and 1,8 T of :  specific total loss ;  specific apparent power ;  r.m.s. value of the magnetic field strength ;  for the measurement up to peak values of magnetic field strength of 1 000 A/m of :  peak value of the magnetic polarization ;  peak value of the magnetic field strength ; b) non-oriented magnetic sheet and strip :  for the measurement between 0,8 T and 1,5 T of :  specific total loss ;  specific apparent power ;  r.m.s. value of excitation current ;  for the measurement up to peak values of magnetic field strength of 10 000 A/m of :  peak value of the magnetic polarization ;  peak value of the magnetic field strength. The single sheet tester is applicable to test specimens obtained from electrical sheets and strips of any quality. The magnetic characteristics are determined for a sinusoidal induced voltage, for specified peak values of magnetic polarization and for a specified frequency. The measurements are made at an ambient temperature of 23 °C ± 5 °C on test specimens which have first been demagnetized. NOTE Throughout this European Standard the quantity "magnetic polarization" is used as defined in!IEC 60050-221". 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

6 3.2.2 Windings The primary and secondary windings shall be at least 440 mm in length and shall be wound on a non-conducting, non-magnetic, rectangular former. The dimensions of the former shall be as follows :  length : 445 mm ± 2 mm ;  internal width : 510 mm ± 1 mm ;  internal height : 520mm− mm ;  height : ≤ 15 mm. The primary winding can be made up of :  either five or more coils having identical dimensions and the same number of turns connected in parallel and taking up the whole length (see figure 3). For example, with five coils, each coil can be made up of 400 turns of copper wire 1 mm in diameter, wound in five layers ;  or a single continuous and uniform winding taking up the whole length. For example this winding can be made up of 400 turns of copper wire 1 mm in diameter, wound in one or more layers. The number of turns on the secondary winding will depend on the characteristics of the measuring instruments. 3.3 Air flux compensation Compensation shall be made for the effect of air flux. This can be achieved, for example, by a mutual inductor. The primary winding of the mutual inductor is connected in series with the primary winding of the test apparatus, while the secondary winding of the mutual inductor is connected to the secondary winding of the test apparatus in series opposition. The adjustment of the value of the mutual inductance shall be made so that, when passing an alternating current through the primary windings in the absence of the specimen in the apparatus, the voltage measured between the non-common terminals of the secondary winding shall be no more than 0,1 % of the voltage appearing across the secondary winding of the test apparatus alone. Thus the average value of the rectified voltage induced in the combined secondary windings is proportional to the peak value of the magnetic polarization in the test specimen. 3.4 Test specimen The length of the test specimen shall be not less than 500 mm. Although the part of the specimen situated outside the pole faces has no great influence on the measurement, this part shall be not longer than it is necessary to facilitate insertion and removal of the test specimen. The width of the test specimen shall be as large as possible and at its maximum equal to the width of the yokes. For maximum accuracy, the minimum width shall be not less than 60 % of the width of the yokes. The test specimens shall be cut without the formation of excessive burrs or mechanical distortion. The test specimen shall be plane. When a test specimen is cut, the edge of the parent strip is taken as the reference direction. The following tolerances are allowed for the angle between the direction of rolling and that of cutting :  ± 1° for grain oriented steel sheet ;  ± 5° for non-oriented steel sheet. For non-oriented steel sheet, two specimens shall be cut, one parallel to the direction of rolling and the other perpendicular unless the test specimen is square, in which case one test specimen only is necessary. SIST EN 10280:2001+A1:2007

± 0,1 %. The test specimen shall be loaded and centred on the longitudinal and transverse axes of the test coil, and the partly counterbalanced upper yoke shall be lowered. SIST EN 10280:2001+A1:2007

8 Before the measurement, the test specimen shall be demagnetized by slowly decreasing an alternating magnetic field starting from well above the value to be measured. 4.3.2 Source setting The source shall be adjusted so that the average value of the secondary rectified voltage is : JARRRNfUˆ4tii22+=
(1) where 2U is the average value of the secondary rectified voltage, in volts ; f is the frequency, in hertz ; iR is the combined resistance of instruments in the secondary circuit, in ohms ; tR is the total resistance of the secondary windings of the test apparatus and mutual inductor, in ohms ; 2N is the number of turns of the secondary winding ; A is the cross-sectional area of the test specimen, in square metres ; Jˆ is the peak value of magnetic polarization, in teslas. The cross-sectional area A is given by the equation : mlmA=
(2) where m is the mass of the test specimen, in kilograms ; l is the length of the test specimen, in metres ; m is the density of the test material determined in accordance with IEC 60404-13, in kilograms per cubic metre. 4.3.3 Measurements 4.3.3.1 The ammeter, if any, in the primary circuit shall be observed to ensure that the current circuit of the wattmeter is not overloaded. The ammeter shall then be short-circuited and the secondary voltage readjusted. After checking the waveform of the secondary voltage, the wattmeter shall be read. The value of the specific total loss shall then be calculated from the equation : ()mi222
