___________
CISPR 15 interpretation sheet on the worst-case mode of operation
Introduction
Subclause 7.5 specifies the operating modes of lighting equipment that must be considered
during an emission test. A few examples are given to support the explanation of what ‘different
operating modes’ means. The list of examples is of course not exhaustive. Apparently, the
example of ‘colour shifting’ is not clear enough and it is sometimes interpreted as if any possible
colour and/or correlated colour temperature (CCT) setting that lighting equipment may produce
shall be assessed during measurements. Many types of LED lighting may be set in many
different colours and CCTs. Compared to other operational-mode related influence quantities
such as light level regulation, flashing or radio communication, the risk of not capturing the
maximum level of electromagnetic (EM) disturbances due to different colour or CCT settings is
very small, provided that all channels of a LED driver used to change colour or CCT are
operative. The ‘colour shifting’-example was meant for example for a mode where the light
output continuously switches from one colour to another with a certain repetition frequency (e.g.

CISPR 14-1:2020(Main)

Electromagnetic compatibility - Requirements for household appliances, electric tools and similar apparatus - Part 1: Emission

CISPR 14-1:2020 specifies the requirements that apply to the emission of radio-frequency disturbances in the frequency range 9 kHz to 400 GHz from appliances, electric tools and similar apparatus as defined below, whether powered by AC or DC (including a battery). This document is applicable to the following equipment:
- household appliances or similar equipment;
- electric tools;
- similar apparatus.
Also included in the scope of this document are separate parts of the above mentioned equipment such as motors and switching devices (e.g. power or protective relays). However, no emission requirements apply to such separate parts, unless otherwise stated in this document. Products which incorporate radio transmit/receive functions are included in the scope of this document. Equipment under the scope of this document making use of IPT is also in the scope. Excluded from the scope of this document are:
- equipment for which all emission requirements in the radio-frequency range are explicitly formulated in other CISPR standards;
- equipment intended to be used only on a vehicle, ship or aircraft;
- equipment used only in industrial environment
- the effects of electromagnetic phenomena relating to the safety of the equipment.
Multifunction equipment may be required to comply with clauses in this and other standards. The details are given in 6.5. The emission requirements in this document are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU including their spurious emissions. This seventh edition cancels and replaces the sixth edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant changes with respect to the previous edition:
- extension of the frequency range for radiated measurements above 1 GHz;
- revision of general test conditions and addition of new specific test conditions (e.g. for robotic equipment);
- introduction of additional requirements for equipment making use of inductive power transfer technology;
- remove from the normative text any compliance requirement based on statistical evaluation;
- revision of clicks analysis, with particular relevance to the determination of the observation time and the application of the upper quartile method for different types of click analysers.
Refer to the Foreword of the document for examples of equipment.

CISPR 15:2018(Main)

Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment

CISPR 15:2018 applies to the emission (radiated and conducted) of radiofrequency disturbances from:
- lighting equipment (3.3.16);
- the lighting part of multi-function equipment where this lighting part is a primary function;
- UV and IR radiation equipment for residential and non-industrial applications;
- advertising signs;
- decorative lighting;
- emergency signs.
Excluded from the scope of this document are:
- components or modules intended to be built into lighting equipment and which are not user-replaceable;
- lighting equipment operating in the ISM frequency bands (as defined in Resolution 63 (1979) of the ITU Radio Regulation);
- lighting equipment for aircraft and airfield facilities (runways, service facilities, platforms);
- video signs;
- installations;
- equipment for which the electromagnetic compatibility requirements in the radio-frequency range are explicitly formulated in other CISPR standards, even if they incorporate a built-in lighting function.
The frequency range covered is 9 kHz to 400 GHz. No measurements need to be performed at frequencies where no limits are specified in this document.
Multi-function equipment which is subjected simultaneously to different clauses of this document and/or other standards need to meet the provisions of each clause/standard with the relevant functions in operation.
For equipment outside the scope of this document and which includes lighting as a secondary function, there is no need to separately assess the lighting function against this document, provided that the lighting function was operative during the assessment in accordance with the applicable standard. The radiated emission requirements in this document are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions.
Within the remainder of this document, wherever the term "lighting equipment" or "EUT" is used, it is meant to be the electrical lighting and similar equipment falling in the scope of this document as specified in this clause. This ninth edition cancels and replaces the eighth edition published in 2013 and its Amendment 1:2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) full editorial revision and restructuring;
b) the restriction to mains and battery operation is deleted in the scope;
c) radiated disturbance limits in the frequency range 300 MHz to 1 GHz have been introduced;
d) the load terminals limits and the CDNE (alternative to radiated emissions) limits have changed;
e) deletion of the insertion-loss requirements and the associated Annex A;
f) introduction of three basic ports: wired network ports, local wired ports and the enclosure port;
g) introduction of a more technology-independent approach;
h) replacement of Annex B (CDNE) by appropriate references to CISPR 16-series of standards;
i) modified requirements for the metal holes of the conical housing;
j) new conducted disturbance measurement method for GU10 self-ballasted lamp;
k) addition of current probe measurement method and limits for various types of ports (in addition to voltage limits and measurement methods);
l) introduction of the term ‘module’ (instead of independent auxiliary) and requirements for measurement of modules using a host (reference) system;
m) modified specifications for stabilization times of EUTs;
n) for large EUT (> 1,6 m), addition of the magnetic field measurement method using a 60 cm loop antenna at 3 m distance (method from CISPR 14-1) as an alternative to the 3 m and 4 m LAS.

CISPR TR 30-2:2012(Main)

Test method on electromagnetic emissions - Part 2: Electronic control gear for discharge lamps excluding fluorescent lamps

CISPR/TR 30-2:2012(E), which is a technical report, details with the aid of reference luminaires, an independent method by which the radio disturbance characteristics of built-in electronic control gear for discharge (excluding fluorescent) lamp luminaires with protection classes I and/or II may be compared against the requirements of CISPR 15. The scope of the part is limited to electronic lamp control gear with an output power (lamp power) up to and including 150 W. Independent electronic lamp control gears are not covered by this technical report; they are within the scope of CISPR 15. This first edition of CISPR/TR 30-2 is published in conjunction with CISPR/TR 30-1. Each part of CISPR 30 series is independent and describes the test set-up for electronic control gear use together with a special lamp family.
