Rob and Steve,
Thanks for the input to the group. The TC100 NWI is also
located on the private pages of the website as is the MOU for the cell phone
chargers for your review.
The HGI-RD015-R3 http://www.homegatewayinitiative.org/publis/HGI-RD015-R3.pdf
shows 3 different dc connectors and also supplies references to a selection of
national standards for mains attachment.
This will be most useful if the groups decides to attack the
supply side of the adapter. There is resistance noted to this direction. I
sense most want to restrict our effort on the DC side.

Subject: Re: Standards references for certification
...and the closely-related ETSI draft standard EN 301
489-34, resulting from the same MoU / EC Mandate M455, dealing with EMC aspects
of (universal) mobile phone chargers. I'd expect that power supplies which aim
to be compatible with a wide variety of user devices will need to have a great
deal of attention paid to EMC.
Although these universal mobile phone standards may not be directly relevant
for certification, they may have transplantable or otherwise interesting bits.
Perhaps of closer relevance, I think mentioned by a previous correspondent, is
the Home Gateway Initiative's standard HGI-RD015-R3, aiming to standardise some
aspects of 10W, 24W and 60W PSUs for, er, home gateways.
Best wishes,
Rob Mann

There is a standard being developed by Cenelec, pr EN 50558,
Interoperability specifications of common external power supply
(EPS) for use with data-enabled mobile telephones.
This has also been circulated by TC100 of the IEC.
It is limited to power supplies with micro USB connection.

In light of
certification, because we do not want "bad" products out there; as I
heard Bob say, herewith a list of standards that I know of, that talk about
power supplies and their performance specifically.
IEEE 1515
IEEE Recommended Practice for Electronic Power
Subsystems: Parameter Definitions, Test Conditions, and Test Methods
IEEE 1573
IEEE Recommended Practice for Electronic Power
Subsystems: Parameters, Interfaces, Elements, and Performance
IEC 60478
Stabilized Power Supplies, d.c. output
IEC 61558
Safety of power transformers, power supply units and
similar
IEC 61204
Low-voltage power supply devices, d.c. output
IPC 9592
Performance Parameters for Power Conversion Devices
As a fan of
harmonization, I would hate to see conflicting demands.
Please feel
free to amend the list.
Best regards,
