Subject: Re: CE or CB ?
Perfect time to ask this question.
A few years ago, I went the CB scheme with a product
that was ITE under the IEC-950 umbrella.
At that time, the CB scheme would only cover power
supplies and not the entire product approval.
Having not done the CB scheme before or since I've
not much experience with it. So here's some questions.
1. Does the CB Scheme actually approve entire product
now instead of just components such as power supplies?
[yes]
2. Does the CB Scheme cover products outside the
IEC-950 ITE category? [yes. see www.cbscheme.org ]
3. When using the CB Scheme for products, a TCF
(Technical Construction File) has to be constructed,
correct? [no. you can use either CB assessment or
a TCF.]
4. Will member countries of the CB Scheme accept
testing and a TCF which has been done entirely
in another country? In other words, can I do all
my CB Scheme tests here in the US to include
national deviations of the intended country of sale,
generate a TCF, then send it off without further
testing to another country?
Or, will there be further testing required?
[You cannot do most of the CB testing. This must be
done by one of the listed authorized CB agencies, e.g.
UL, CSA, TUVR, SEMKO, ......... The resulting CB Test
Report, if done thoroughly and accurately, will be
automatically accepted in many countries. However,
all CBs being asked to "recognize" the report of another
CB have the right to request a sample to compare to the report.
Any further testng they may do is not billable to you
as you have already paid the original CB agency for all
the IEC 60950 tests. An exception is if you failed to
ask the issuing CB to include all CB country differences.]
