Anthony, Charlie and Bob,
Thanks for all of your responses but, it appears the issue is not entirely resolved and probably won’t be until the replacement standard is issued. I think I understand the overall intent of the standard unfortunately, the terminology used in the standard leaves this open to interpretation. Charlie, like you, my initial interpretation of the applicability of this requirement would have been to restrict the use to intentional radiators. This initial view may have been due to my exposure to wireless certifications and the various requirements associated with the R&TTE Directive. If I were able to approach this standard without any prior knowledge of the R&TTE, strictly Product Safety or EMC then, my initial interpretation may have fallen on the other side of the fence. Wouldn’t it be ideal if the Scope of a standard were to clearly answer a few basic questions like; who or what is this requirement intended to protect, why is this protection required and how this standard is supposed to provide this protection.

It applies to safety relating to RF Exposure or Specific Absorbsion Rate (SAR). For Europe, it should be applied in conjunction with Council Recommendation 1999/519/EC (or IMHO the ICNIRP guidelines) which define RF exposure limits. It applies to apparatus where there is no dedicated RF exposure harmonised standard, i.e. everything except mobile phones (EN 50360), article surveillance / RFID (EN 50364), radio & telecoms fixed base stations (EN 50385 & EN 50401). Normally applies only to intentional transmitters having an average radiated power greater than 20mW, transmitters equal or lower than this are deemed to comply without further assessment. However, unintentional radiators with emissions above this level should be assessed, there is a responsibility for safety to RF exposure regardless of whether the RF is intentional or otherwise. Unintentioal emitters abover the 20mW threshold are likely to have serious EMC emissions issues! Incidentally, there is another generic RF exposure harmonised standard, EN 62311:2008 which covers the spectrum down to 0Hz and includes much detail regarding assessment methods.
