IEC 61000-6-3:2011 pdf – Electromagnetic compatibility (EMC)- Part 6-3: Generic standards -Emission standard for residential, commercial andlight-industrial environments.
3,2 3.1.2
enclosure port
physical boundary of the apparatus which electromagnetic fields may radiate through or impinge on
32 3.1.3
cable port
port at which a conductor or a cable is connected to the apparatus
NOTE Examples are signal, control and power porte.
3.4 3.1.4
telecommunlcatlonslnetwork port
point of connection for voice, data and signalling transfers intended to interconnect widely dispersed systems via such means as direct connection to multi-user telecommunications networks (e.g. public switched telecommunications networks (PSTN) integrated services digital networks (ISDN). x-type digital subscriber lines (XDSL). etc.). local area networks (e.g. Ethernet, Token Ring, etc.) and similar networks)
NOTE A port generally intended for interconnection of components of an ITE system under test (e.g. RS-232.RS-
485, field buses in the scope of IEC 61158. IEEE Standard 1284 (parallel printer). Universal Serial Box (USBI.
IEEE Standard 1394 lFlre Wire). etc.l and used in accordance with its functional specifications (e.g. for the
vnaxmum length of cable connected to it). is not considered to be a telecommunications porl.
3.5 3.1.5
power port
port at which a conductor or cable carrying the primary electrical power needed for the operation (functioning) of an apparatus or associated apparatus is connected to the apparatus
36 3.1.6
public mains network
electricity lines to which all categories of consumers have access and which are operated by
a supply or distribution undertaking for the purpose of supplying electrical energy
3.-i 3.1.7
low voltag.
low tension
voltage having a value below a conventionally adopted limit
[1EV 601-01-26. modified]
NOTE For the distnbution of AC electric power, me upper limit Is generally accepted to be 1 000 V.
3.1 3.1.8
d.c. power network
local electricity supply network in the infrastructure of a certain site or building intended for flexible use by one ore more different types of equipment and guaranteeing continuous power supply independently from the conditions of the public mains network
NOTE Connection to a remote local battery Is not regarded as a DC power network, If such a link comprises Only power supply for a single piece of equipment.
low voltage AC mains port
4 Conditions during testing
The equipment under test (EUT) shall be tested in the operating mode producing the largest emission in the frequency band being investigated, e.g. based on limited pretests and consistent with normal applications. The configuration of the test sample shall be varied to achieve maximum emission consistent with typical applications and installation practice
If the apparatus is part of a system, or can be connected to auxiliary apparatus, the apparatus shall be tested while connected to the minimum representative configuration of auxiliary apparatus necessary to exercise the ports in a similar manner to that described in CISPR 22.
In cases where a manufacturer’s specification requires external filtering and/or shielding devices or measures that are clearly specified in the user’s manual, the measurement requirements of this standard shall be applied with the specified devices or measures In place.
The configuration and mode of operation during the measurements shall be precisely noted in the test report. If the apparatus has a large number of similar ports or ports with many similar connections, a sufficient number shall be selected to simulate actual operating conditions and to ensure that all the different types of termination are covered.
The measurements shall be carried out at one single set of parameters within the operating ranges of temperature, humidity and atmospheric pressure specified for the product and at the rated supply voltage, unless otherwise indicated in the basic standard.
Where applicable, additional information on EUT configuration can be found in the CSPf 10-2 series and CISPR 22.
5 Product documentation
The purchaserluser shall be informed if special measures have to be taken to achieve compliance, e.g. the use of shielded or special cables,
6 ApplIcabIlity
The application of measurements for emission(s) depends on the particular apparatus, its configuration. its ports, its technology and its operating conditions
Measurements shall be applied to the relevant ports of the apparatus according to Tables 1 to 4. Measurements shall only be carned out where the relevant ports exist.
It may be determined from consideration of the electrical characteristics and usage of a particular apparatus that some of the measurements are inappropriate and therefore unnecessary. In such a case it Is required that the decision and justification not to measure shall be recorded in the test report.
