No need to limit yourself to 60950 either. Specifically for battery operated
equipment, you can use a standard like 60335 that has requirements for battery
operated appliances. From the Annex use the testing and construction and user
instructions from that standard.

Subject: Re: [PSES] Do it yourself safety reports?
I agree with John, batteries are the most critical part. Make sure
they are properly approved, and use a fuse in their leads.
As it's an RF product, I suppose the LVD comes into play by
means of the RTTE (RED) directive.
So a full qualification is needed.
Many aspects do not apply, but the remaining
applicable chapters need evaluation.
That requires evaluation of the battery, and possibly fire and heat hazards
if the power exceeds "limited power levels". (antenna voltage > 50 ?)
Documentation, marking and labelling
and a proper definition (intended use) is needed. Installation
and safety documentation might be needed.
If the battery is chargeable and a power supply is included it needs
verification of its documentation and needs reinforced insulation,
both mechanically and electrically, as the secondary "live parts" are rarely
earthed in these type
of equipment's and often must be be classified as accessible parts.
Plastics need may not propagate fire, and should have the right V Class.
More aspects can be applicable.....
making your own test report is possible, but I doubt if it will stand up
against examination, unless you have done this before...

If it's battery-powered, the LVD may not apply, so in turn there is no need to
apply 60950. But I would advise applying it as far as possible. We don't want
more battery fires, so that is one point to look at carefully; can the battery
be short-circuited by a fault and if so, what happens? It's certainly possible
to do that without a test house, but of course, it has to be done carefully.

Subject: [PSES] Do it yourself safety reports?
A client is asking if it is practical to do their own 60950 safety reports for
CE.
The device is battery powered, low power RF (they would have complete EMC
testing done at a lab).
Thanks in advance for your suggestions.
Thanks for all the great past advice!
