This part of IEC 61000 relates to the conducted immunity of electrical and electronic equipment to electromagnetic disturbances coming from intended and/or unintended broadband signal sources having frequency contributions in the frequency range 150 kHz up to 80 MHz. The object of this standard is to establish a common reference to evaluate the immunity of electrical and electronic equipment when subjected to conducted disturbances caused by intended and/or unintended broadband signal sources (such as power line telecommunication systems) on AC mains ports. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. Equipment not having at least one AC mains port is excluded. Power ports not connected to AC mains are not considered AC mains ports and therefore they are excluded. The standard is applicable only to single phase equipment having rated input current d" 16 A; the application of the broadband disturbance to multiple phase equipment and/or equipment with rated input current > 16 A is under consideration. NOTE 1 As described in IEC Guide 107, this standard is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products. NOTE 2 Power Line Telecommunications (PLT) is also known as Broadband Power Line (BPL) and as Power Line Communication (PLC).
