CISPR 15:2018

CISPR 15 is an EMC emission standard that specifies limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment. Currently, the 9th edition of this standard (CISPR 15:2018, published in 2018) is available and valid.

The CISPR 15:2018 EMC emission measurement standard specifies the EMI emission limits (conducted & radiated), methods of measurements, test procedure, and other related details for emission measurement tests for electrical lighting equipment & similar equipment. This standard covers a frequency range of 9 kHz to 400 GHz. This standard ensures that the electrical lighting equipment & similar equipment that complies with this standard do not emit more than the EMI emission limit specified in this standard and do not interfere with other devices or systems in the same environment.

This standard applies to the emission requirements (both radiated and conducted) of radiofrequency disturbances from the following:  

• Lighting equipment ;        
• Multi-function equipment's lighting part where this lighting part is a primary function;
• IR and UV radiation equipment used for residential and non-industrial applications;
• Advertising signs;
• Decorative lighting;
• Emergency signs.
• The scope of this document excluded the following:
• The components or modules intended to be built into lighting equipment and which are not user-- replaceable;
• The lighting equipment that uses/operates in the ISM frequency bands (as defined in Resolution 63 (1979) of the ITU Radio Regulation);
• Lighting equipment used for aircraft and airfield facilities (e.g., runways, service facilities, platforms);
• Video signs;
• Installations;
• The equipment for which the EMC emission requirements in the radio-frequency range are explicitly formulated in other CISPR standards, even if they have a built-in lighting function.

This document says that no measurement tests are needed at frequencies where no limits are specified in this document. Also note that for equipment outside the scope of this document/standard 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 in operation during the assessment in accordance with the applicable standard. This document's radiated emission requirements do not apply to any deliberate transmissions from a radio transmitter, as defined by the ITU (International Telecommunication Union), nor to any spurious emissions that may arise from these intentional transmissions.

This ninth third edition supersedes the eighth edition, which was published in 2013, and its Amendment 1:2015. This ninth edition features significant technical changes from the previous edition, some of which are listed below.

• This document is a full editorial revision and restructured;
• This document deleted the restriction to mains and battery operation;
• Document deletes   the insertion-loss requirements and the associated Annex A;
• Introduced three basic ports: wired network ports, local wired ports, and the enclosure port;
• Introduced a more technology-independent approach;
• Modified requirements for the metal holes of the conical housing are provided in this document;
• This document features new conducted disturbance measurement method for GU10 self-ballasted lamp;
• In addition to voltage limits and measurement methods, this document has current probe measurement method and limits for various types of ports;
• This document has modified specifications for the stabilization times of EUTs;
• This document introduced the term ‘module’ (Instead of independent auxiliary).
