On 27th August 2014, the FCC published a Draft OET Laboratory Publication (KDB 640677 D01) – “RF Lighting Products Must Meet All FCC Standards to Mitigate potential Harmful Interference to Radio Services”.
This new publication clarifies the requirements for lighting devices that are subject to Part 15 or Part 18 rules, outlining a requirement for radiated measurements to be performed up to 1000 MHz. This supersedes the Part 18.309 rule, whereby radiated emissions measurements were not routinely required.
Industry Canada has announced that ICES-005 Issue 4 – “Radio Frequency Lighting Devices” - will be revised to adopt IEC CISPR 15 standard, Edition 8, May 2013. Interim guidelines extend the frequency range of the radiated emission limits up to 1 GHz.
The changes mean that the current radiated emission limit (applicable at 300 MHz) would also apply in the 300 MHz-1GHz frequency range. A wider range of lighting equipment such as dimmers which are currently not covered by ICES-005 (i.e. RFLDs) will be included in the upcoming version of ICES-005.
It is anticipated that from 1st January 2015, manufacturers will be required to ensure compliance with these new requirements. To avoid enforcement actions and possible sanctions, the FCC and Industry Canada strongly encourage manufacturers to resolve any instances of harmful interference that may occur, recommending the use of accredited test laboratories to ensure that testing is carried out in accordance with these new procedures.
