EU standard 55015 (CISPR15)
As/NZ standard 4051

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

This standard applies to the emission (radiated and conducted) of radio frequency disturbances from and to the immunity to radio frequency disturbances of:

all lighting equipment with a primary function of generating and/or distributing light intended for illumination purposes, and intended either for connection to the low voltage electricity supply or for battery operation;
the lighting part of multi-function equipment where one of the primary functions of this is illumination;
independent auxiliaries exclusively for use with lighting equipment;
UV and IR radiation appliances;
neon advertising signs;
street/flood lighting intended for outdoor use only;
transport lighting (installed in buses, trains, etc.).

Excluded from the scope of this standard are:

apparatus for which the electromagnetic compatibility requirements in the radio frequency range are explicitly formulated in other IEC or CISPR standards.
Note - Examples are:
- built-in lighting devices in other equipment, for example scale illumination or neon indicators;
- photocopiers;
- slide projectors.

Radiated:

Requires the use of a ‘Large Loop Antenna’ (van Leen Loop) antenna to measure the level of RF energy radiated from the product into ‘space’. Frequency range 9KHz to 30MHz.

Conducted:

The RF conducted back down the mains lead is measured preferably with a LISN (Line Impedance Stabilisation Network), or alternatively with a voltage probe if a LISN is not suitable. Frequency range 9KHz to 30MHz.

The signals from the antenna, LISN or voltage probe are all analysed in a CISPR16 EMC analyser.

The complete basic kit to cover both radiated and conducted emissions measurement in accordance with the standard, including a 16A single phase LISN and RF300 large loop antenna ...RFG-4L
A comprehensive range of alternative LISNs for up to 150A rating and 3 phases are available. If applicable, a voltage probe can be supplied in place of the LISN. ...RFG-5L
Recommended option: RF910 pre-selector. Essential if the EUT generates broadband noise (e.g. light dimmers, power controllers, phase angle controllers) ...add -R

SA1000 EMC analyser
RF300 large loop antenna

Help in the selection of the appropriate measurement techniques and automatic display of the relevant limit levels are standard features in the software provided with all Laplace EMC analysers.
