37、e 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 is
38、olation 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
39、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
40、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.

41、 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 st
42、andard. 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 eq
43、uipment 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 em
44、ission 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
45、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 comp
46、liance with the radiation disturbance limits specified herein. Class B resistance welding equipment shall be measured on a test site.
