Hello Richard
The product is a demonstration fixture to be used by our distributors in the
sales process and will not be sold to the general public....I should have been
a little clearer when I said "Do some internal testing" The plan is to
evaluate the product to IEC60065 and complete a CB test report form as part of
a TCF. The confusion comes in as follows
1. If the external power supply has a CE and TUV GS Mark does the low voltage
product require a CE Mark and DoC for the LVD? The responses I received have
ranged from "not required on the end product but would be useful to avoid
hassles" to " The product and power supply combo are considered to be mains
connected so the complete unit must be CE Marked". Since this is not clearly
defined in any EU document I could find I will err on the side of caution and
require the DoC to reference the LVD and CE Mark the low voltage audio
product. Simple enough as this is a self declaration in any case......
2. A bigger concern and cost is whether it is prudent to pay the expense to
get a CB certification for the product for use in Asia, i.e. China, Taiwan,
Singapore, Korea etc.... I can complete a CB report for the CE mark TCF but I
am wondering if a CB is a necessary investment for Asia. Will the above
mentioned countries insist on the system getting the local approval Mark or is
it sufficient for the power supply to have the correct local authority
approvals? The easy way out is to just go for a CB cert but this is a low
volume product and is cost sensitive..............Any thoughts???
Thanks to everyone for your opinions as they are very helpful.
regards,
John

John,
Further to my earlier Email, and those from others, you need to consider how
you are going to supply your product and any spare parts.
As I mentioned earlier and as has been expanded upon by others, if you are
going to supply the complete product in a single box then that will need to be
CE marked. Under the LVD it is not mandatory to supply a DoC with each
product (e.g. in each box), though you could do so if you wish.
Of course, it may also be that the auxiliary speakers and power cubes that
operate at ELV could get damaged and you may wish to supply these individually
as spare parts. In this case, these items do not fall within the LVD and so
they must not be CE marked in respect of the LVD. They do fall within the
scope of the General Product Safety Directive, as mentioned previously.
The level of testing you are suggesting {e.g. "do some internal testing to
verify there is no fire hazard as a result of amplifier shorts etc"} would
seem to fall short of that required by EN 60065. If you are not planning to
use a Harmonised Standard then what is the yardstick you are planning to use
to determine how safe your product is?
