29、 EN 50199: 1995 BSI 1996 1 Scope This standard is applicable to equipment for arc welding and allied processes designed for use in industrial and domestic establishments. Included are welding power sources, wire feeders and ancillary equipment, e.g. water coolers and arc striking and stabilizing dev
30、ices. The frequency range covered is from 0 Hz to 400 GHz. This standard is not applicable to: arc welding torches, guns, electrode holders, cables and coupling devices. NOTE 1. Allied processes are, for example, plasma cutting and arc stud welding. NOTE 2. Limits are not specified over the whole fr
31、equency range. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendmen
32、ts to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

40、ing 3 Objectives 3.1 Emission The objective of this standard is to define limits and test methods for electromagnetic emissions which may cause interference in other apparatus. These emission limits represent essential electromagnetic compatibility requirements. They have been selected to minimize t
41、he disturbances generated by the welding equipment when operated normally. NOTE 1. The limits in this standard may not, however, provide full protection against interference to radio and television reception when the welding equipment is used closer than 30 m to the receiving antenna(e). NOTE 2. In
42、special cases, when highly susceptible apparatus is being used in close proximity, additional mitigation measures may have to be employed further to reduce the electromagnetic emissions.

43、 EN 50199: 1995 BSI 1996 3.2 Immunity The objective of this standard is to define immunity requirements and test methods for continuous and transient, conducted and radiated disturbances including electrostatic discharges. The test requirements represent essential electromagnetic compatibility immun
44、ity requirements. They have been selected to ensure a level of immunity for apparatus at industrial establishments. These levels do not, however, cover extreme cases which may occur with an extremely low probability of occurrence in any location. NOTE. This standard does not specify basic safety req
45、uirements for welding equipment such as protection against electric shock, unsafe operation, insulation coordination and related dielectric tests. 4 Definitions Definitions related to EMC and to the relevant phenomena may be found in IEV 50, chapter 161 and in CISPR publications. Definitions related
46、 to arc welding equipment may be found in IEV 50 chapter 851 and in EN 60974-1. 4.1 conventional valueEN 60974-1 A 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 actua
47、l welding process. 4.2 conventional loadEN 60974-1 A practically non-inductive constant resistive load as defined in IEC 974-1. 4.3 duty cycle; duty factor (X)EN 60974-1 The ratio for a given time interval of the on-load duration to the total time. NOTE 1. This ratio, lying between 0 and 1 may be ex
48、pressed as a percentage. NOTE 2. For the purposes of this standard, the time period of one complete cycle is 10 min, e.g. in the case of 60 % duty cycle (duty factor), load is applied continuously for 6 min, followed by a no-load period of 4 min. 4.4 conventional welding current (I2) EN 60974-1 The
49、current delivered by a welding power source to a conventional load at the corresponding conventional load voltage. NOTE. The values ofI2are given as r.m.s. values for a.c. and arithmetic mean values for d.c. 4.5 conventional load voltage (U2)EN 60974-1 The load voltage of a welding power source having a specified linear relationship to the conventional welding current. NOTE 1. The values of U2are given as r.m.s. values for a.c. and arithmetic mean values for d.c. NOTE 2. The specified linear relation
