Terms and definitions relating to EMC may be found in IEC 60050-161 and in CISPR publications. In addition, the terms and definitions relating to resistance welding equipment may be found in IEC 60050-851, IEC 62135-1 and ISO 669. 3.1 cable port point at which a conductor or a cable is connected to the apparatus NOTE 1 Examples are signal, control and power ports. NOTE 2 The secondary circuit of resistance welding equipment is not a cable port but is part of the enclosure port. 3.2 conventional load load condition with the electrodes short-circuiting as defined in ISO 669:2000 3.3 conventional value standardized value that is used as a measure of a parameter for the purposes of comparison, calibration, testing, etc. NOTE Conventional values do not necessarily apply during the actual welding process. 3.4 enclosure port physical boundary of the apparatus through which electro-magnetic fields may radiate or impinge 3.5 idle state operating mode in which the power is switched on, but the welding circuit is not energized 3.6 port particular interface of the specified apparatus with the external electro-magnetic environment 4 General test requirements 4.1 Test conditions Tests shall be carried out within the specified operating conditions for the apparatus at its rated supply voltage and frequency as given in IEC 62135-1. Results obtained for r.f. emission and immunity at 50 Hz are valid for the same model operating at 60 Hz and vice versa. 4.2 Measuring instruments The measuring equipment shall comply with the requirements of CISPR 16-1-1 and the standards referred to in Tables 1, 2 and 3 as applicable. BS EN 62135-2:2008 7 Licensed CopyChinese University of Hong Kong, 21/10/2008 03:41, Uncontrolled Copy, (c) BSI The measuring equipment for low-frequency emission tests shall be in conformity with the requirements of IEC 61000-4-7 for harmonics and IEC 61000-4-15 for voltage fluctuation. 4.3 Artificial mains network Measurement of the mains terminal disturbance voltage shall be made using an artificial mains network consisting of 50 /50 H V-network as specified in CISPR 16-1-2. The artificial network is required to provide a defined impedance at r.f. across the mains supply at the point of measurement and also to provide for isolation of the equipment under test from ambient noise on the power lines. 4.4 Voltage probe A voltage probe shall be used when the artificial mains network cannot be used. The probe is connected sequentially between each line and the reference earth. The probe shall consist of a blocking capacitor and a resistor such that the total resistance between the line and earth is at least 1 500 . The effect on the accuracy of measurement of the capacitor or any other device which may be used to protect the measuring receiver against dangerous currents shall be either less than 1 dB or allowed for in calibration. 4.5 Antennas In the frequency range from 30 MHz to 1 GHz the antenna(s) used shall be as specified in CISPR 16-1-4. Measurements shall be made for both horizontal and vertical polarization. The nearest point of the antenna(s) to the ground shall be not less than 0,2 m. 5 Test set-up for emission and immunity 5.1 General requirements Emission and immunity testing shall be carried out on a representative resistance welding installation as described below. Resistance welding equipment tested in such an installation shall be considered to have met the necessary requirements of this standard. If the resistance welding equipment is part of an installation, or can be connected to auxiliary equipment, then the resistance welding equipment shall be tested whilst connected to the minimum configuration of auxiliary equipment necessary to exercise the ports. If the resistance welding equipment has a large number of similar ports or ports with many similar connections, then a sufficient number shall be selected to simulate actual operating conditions and to ensure that all the different types of termination are covered. Measurements to determine compliance with the low-frequency emission limits shall be made in accordance with the test procedures of relevant basic and referenced standards. Specific test set-up geometries for immunity tests are found in the basic standards referred to in Tables 1, 2 and 3. The configuration of the resistance welding equipment under test shall be precisely noted in the test report. Class A resistance welding equipment may be measured either on a test site or in situ as preferred by the manufacturer. NOTE Due to size, complexity or operating conditions, some resistance welding equipment may have to be measured in situ in order to show compliance with the radiation disturbance limits specified herein. Class B resistance welding equipment shall be measured on a test site.
