Hello Brian, I've had one eye on this for a few years. I haven't had time to follow through the links you provide but I do have some possibly relevant info.
There is some interesting background here: http://ec.europa.eu/enterprise/sectors/rtte/chargers/index_en.htm The "Docs & Links" link on the left of the above page takes you to the original Memorandum of Understanding and some provisional technical requirements. There is also a mandate to CENELEC to produce harmonised standards for such a charger. There is a R&TTE Directive EMC Harmonised Standard for the common charger, EN 301 489-34 which is freely available here: http://webapp.etsi.org/ewp/copy_file.asp?wki_id=39521 Now some gossip. There have been murmurings in Brussels for many years about the inconvenience of a multitude of mobile phone chargers and some personal agendas (allegedly) to want to standardise. After many patient years of waiting, those parties have seized upon the 'green' policies of efficiency and waste to push this through. Personally, I think standardisation is a good thing for the consumer and the environment, but clearly not so good commercially for the manufacturers. So after years of resistance and under the threat of compulsory legislation the major manufacturers sign a voluntary Memorandum of Understanding to agree and comply with a common mobile phone charger. It's all a joke really. We're part way there in that most smart-phones at least adopt, by default, a micro USB serial data and power port but that's because you need to connect most smart-phones to a PC anyway. Plus, 'm pretty sure all manufacturers state that using non-approved accessories (i.e. not their own brand) can yield unpredictable results and invalidate warranties. It's clear that Apple have no immediate intention of complying, perhaps other than by the user purchasing special adapters. I know of one major smart phone manufacturer who declares in their technical documentation that their micro USB charger is not intended to comply with the Common Charger spec (therefore not having to test to EN 302 489-34). I know of another major phone manufacturer who declares their phones are for portable use only in the context of EN 301 489-1 and don't do any EMC conducted immunity or emissions testing at all, even though they supply chargers with their smart-phones. EN 301 489-1 is available here: http://webapp.etsi.org/ewp/copy_file.asp?wki_id=30979 Hope this is of interest. I've followed this a while and I'd appreciate any further information. Cheers, T ----- Original Message ----- From: Brian Oconnell Sent: 03/20/14 07:31 PM To: [email protected] Subject: [PSES] common charger for radio equipment So the EU releases something for the Radio Equipment Directive: <http://www.europarl.europa.eu/sides/getDoc.do?pubRef=-//EP//TEXT+TA+P7-TA-2014-0246+0+DOC+XML+V0//EN> Which say this: "A renewed effort to develop a common charger for particular categories or classes of radio equipment is necessary, in particular for the benefit of consumers and other end-users; this Directive should therefore include specific requirements in that area. In particular, mobile phones that are made available on the market should be compatible with a common charger" Had not given much thought to this until a scope statement or definition for the particular class of equipment affected was nowhere to be found. Can someone point me to this info? Will the EU scope the 'common' charger for all hand-held radio equipment, or just mobile phones? Or perhaps the King of Brussels intended to say "chargers for the commoners"?
