25、llary equipment, for example wire feeders, liquid cooling systems and arc striking and stabilising devices. NOTE 1 Allied processes are, e.g., plasma cutting and arc stud welding. NOTE 2 This standard does not specify basic safety requirements for arc welding equipment such as protection against ele
26、ctric shock, unsafe operation, insulation co-ordination and related dielectric tests. Arc welding equipment type tested in accordance with, and which has met the requirements of, this standard is considered to be in compliance for all applications. 1.1 Emission The objective of this standard is to s
27、pecify a) test methods to be used in conjunction with CISPR 11 and its amendments 1 and 2 to determine electromagnetic emissions; b) relevant standards for harmonic current emission, voltage fluctuations and flicker. 1.2 Immunity The objective of this standard is to define immunity requirements and
28、test methods for continuous and transient, conducted and radiated disturbances including electrostatic discharges. NOTE 3 These requirements do not cover extreme cases, which may occur with an extremely low probability of occurrence in any location. 2 Normative references The following referenced do

Page 5 EN 6097410:2003 069-4710 IEC:02 20 6 4 General test requirements Tests shall be carried out within the specified operating conditions for the apparatus, as given in IEC 60974-1, and at its rated supply voltage and frequency.
39、 Results obtained at 50 Hz are valid for the same model operating at 60 Hz and vice versa. The conformity of the equipment shall be assessed in accordance with 11.2 or 11.3 of CISPR 11:1997. The measuring equipment shall comply with the requirements of CISPR 16-1 and the standards referred to in tab
40、les 1, 2 and 3 as applicable. 5 Test set-up for emission and immunity 5.1 General Emission and immunity testing shall be carried out on a typical arc welding installation according to figure 1. Arc welding equipment tested in such an installation shall be considered to have met the necessary require
41、ments of this standard. If due to the design of the arc welding equipment, these tests cannot be carried out as described, the manufacturers recommendations (e.g. temporary bypassing or disablement of control circuits) should be followed in order to match these test objectives. Any temporary changes
42、 to the arc welding equipment shall be documented. The configuration of the equipment under test shall be noted in the test report. 5.2 Welding power source If the welding power source is part of an installation, or can be connected to ancillary equipment, then the welding power source shall be test
43、ed whilst connected to the minimum configuration of ancillary equipment necessary to exercise the ports. If the welding power source 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 e
44、nsure that all the different types of termination are covered. Specific test set-up geometries for immunity tests can be found in tables 1, 2 and 3. The conventional load shall be insulated by an insulating mat (or blocks) not greater than 12 mm thick. The welding power source shall be similarly ins
45、ulated from the ground plane or insulated by its own undergear if appropriate. For radiated emission tests, the welding power source and conventional load shall be positioned equidistant from the test antenna, see figures 1 and 2.

The welding power source shall be connected to the conventional load by welding cables of suitable cross-section for the welding current, or the appropriate
49、torch or electrode holder with adapter. The welding cables shall have a minimum length of 2 m. The cables shall be allowed to fall naturally to the ground plane. Excess input, welding or torch cables shall be folded to and forth, as far as practicable to form a bundle not exceeding 0,4 m in length. Page 7 EN 6097410:2003 069-4710 IEC:02 20 8 5.3 Ancillary
