Scope

This standard applies to electrical equipment using signals in the frequency range 1,6 MHz to 30 MHz
to transmit information on low voltage electrical systems, either on the public supply system or within
installations in consumers’ premises.
It does not specify the signal modulation methods nor the coding methods nor functional features.
Environmental requirements and tests are not included.
The immunity requirements have been selected so as to ensure an adequate level of immunity for
apparatus at residential, commercial and light industrial premises (Class 1 environment), and industrial
premises supplied from a dedicated HV/MV or MV/LV transformers (Class 2 environment).

The severity levels required by this standard may not cover extreme cases which may occur in any
location but with a low probability of occurrence. In special cases situations will arise where the level
of disturbances may exceed the levels specified in this standard (e.g. where a hand-held transmitter is
used in proximity to an apparatus). In these instances special mitigation measures may be required.

Objective

The objective of this standard is to define the immunity test requirements for apparatus defined in the
scope in relation to continuous and transient, conducted and radiated disturbances including
electrostatic discharge.
Test requirements are specified for each port considered.

Description of locations

Locations which are characterized by being supplied directly at low voltage from the public mains
network are considered to be Class 1 environments.
Examples of Class 1 locations are as follows:
–

residential properties, e.g. houses and apartments;

–

retail outlets, e.g. shops and supermarkets;

–

business premises, e.g. offices and banks;

–

areas of public entertainment e.g. cinemas, public bars and dance halls;

–

outdoors locations e.g. petrol locations, car parks, amusements and sports centres;

–

light-industrial locations e.g. workshops, laboratories and service centres.

ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ


Class 2 locations are characterised by the existence of one or more of the following conditions:
–

a power network exists powered by a high or medium voltage power transformer dedicated for
the supply of an installation feeding manufacturing or similar plant;

–

industrial, scientific and medical (ISM) apparatus are present;

–

heavy inductive or capacitive loads are frequently switched;

–

currents and associated magnetic fields are high.

6

Conditions during testing

A minimum test configuration consists of two pieces of powerline communications equipment
interconnected with manufacturer specified physical cable. Associated equipment necessary to the
function of the powerline network shall be included in the test configuration.
The system shall be capable of transmitting and receiving data at the nominal transmission rate
specified by the manufacturer.
The powerline equipment shall execute a programme that exercises all the functions available to the
end user. As a minimum the functions described in Clause 7 of this standard “Performance criteria”

shall be tested.


EN 50412-2-1:2005

Performance criteria

Performance criterion A

During and after the test, the EUT shall operate without
–

protocol failure,

–

loss of link,

–

any other loss of functions relevant to the user,

–

reduction in performance below that declared by the manufacturer. The manufacturer shall
choose the most appropriate performance measurement criteria for their apparatus or system e.g.

bit error rate, block error rate, throughput, re-transmissions etc.

Performance criterion B

Degradation of the performance beyond that as described in criterion A is permitted during the
application of the test provided that the normal operation of the EUT is self-recoverable to the
condition immediately before the application of the test.
Performance criterion C

Degradation of the performance beyond that as described in criterion A is permitted during the
application of the test provided that the normal operation of the EUT is self recoverable to the
condition immediately before the application of the test or can be restored after the test by the
operator.

Narrow band responses & radio-frequency continuous conducted tests

This clause is applicable to Clause 10, Applicability, tests 3.1, 4.1, 5.1, 6.1, 7.1, 8.1 and 9.1
8.1

Tests on narrow band devices

A narrow band device is defined as a device that uses a maximum of two simultaneous carriers e.g.
one upstream and one downstream carrier.
Narrow band devices shall benefit from exclusion bands in which radio-frequency continuous conducted
common mode tests are not made.


The exclusion bands are determined the same way for both the transmitter and the receiver of a
device.
Exclusion band definition for receivers or receivers which are part of transceivers:

Responses of receivers or the receiver part of (duplex) transceivers occurring during the immunity
tests at discrete frequencies which are narrow band responses (spurious responses), are identified by
the following method.
If during the test, the immunity RF test signal causes non-compliance of the receiver with the specified
performance criteria (see Clause 7), it is necessary to establish whether this non-compliance is due to
a narrow band response or a wideband phenomenon. Therefore, the frequency of the test signal is
increased by an amount equal to twice the nominal 6 dB bandwidth of the IF filter immediately
preceding the demodulator of the receiver, or if appropriate, the bandwidth over which the apparatus is
intended to operate, as declared by the manufacturer. The test is repeated with the frequency of the
test signal decreased by the same amount.


–9–

EN 50412-2-1:2005

If the receiver is then in either or both frequency offset cases in compliance with the specified
performance criteria, the response is considered as a narrow band response.
If the receiver still does not comply with the specified performance criteria, this may be due to the fact
that the offset has made the frequency of the unwanted signal correspond to the frequency of another
narrow band response. Under these circumstances the procedure is repeated with an increase and
decrease of the frequency of the test signal adjusted two and a half times the bandwidth referred to
above.
If the receiver still does not comply with the specified performance criteria in either or both frequency
offset cases, the phenomena is considered wide band and therefore an EMC problem and the
equipment fails the test.

For immunity tests, narrow band responses shall be disregarded.
It is recommended that for narrow-band systems the manual should contain a warning that the
equipment may be susceptible to interference.
8.2

Tests on broad band devices

A broadband device is a device that uses 3 or more carriers simultaneously, OFDM, multicarrier
modulation, spread spectrum technologies etc.
Broadband devices shall not benefit from an exclusion band for the radio-frequency continuous conducted
common mode tests.

ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ

Broadband devices may incorporate adaptive algorithms that interact with the swept frequency test
signal used for radio-frequency continuous conducted tests. Radio frequency ingress, in practice, will
typically be a combination of multiple single frequency fixed interferers and broadband noise.
Consequently, the dwell time of the swept frequency test signal shall be chosen such that the
apparatus or system performance is not adversely affected beyond that which would occur with a fixed
or broadband interferer.

9

Product documentation

The specification used by the manufacturer to define the performance criteria for the testing required
by this standard shall be made available upon request.

10 Applicability
Tests shall be applied to the relevant ports of the equipment according to Tables 1 to 9. Tests shall

only be carried out where the relevant port exists.
It may be determined from consideration of the electrical characteristics and usage of a particular
equipment that some of the tests are inappropriate and therefore unnecessary. In such a case, it is
required that both the decision and the justification not to apply any particular test to any particular port
be recorded in the test report.
