The link posted to the site of Bob, G4UJS 
(http://g4ujs.shacknet.nu/spe_2k-fa.pdf) suggests that they should be, as they 
claim ISO9000 QA.
However, under the terms of the Radio & Telecommunications Terminals Directive 
(R&TTED), a manufacturer or importer with a suitable QA policy and organisation 
(ISO 9000) may self certify against a Harmonised Standard.  A couple of years back, an 
assessment by the EC showed something like  70% of Short Range Devices (SRD) and about 
30% of professional stuff such as Private Mobile Radio  failed to comply, although the 
vast majority of cases were a failure to have correct paperwork rather than a failure 
to meet technical requirements.


"
In general" ISO "only guarantees that they have properly documented what they have done, or what they have done matches the documentation.

For instance ISO9002 has absolutely nothing to do with how well a device or product does its job, or even if it works at all, just that they have properly documented it.

Many companies fail their certification because the go into too much detail in the documentation.

In my projects we had FDA validation under ISO guidelines.
Even going with minimal docs we started with about an inch high packet. Every action and its results had to be printed our resulting in a stack over 4 feet tall. That's about 5 reams of paper. Thing is, this was all on the process. there was not one mention of the produce in the whole operation.

Now other ISO regs may bedifferent, but the original idea behind ISO certification was only about the proper recording of what the company did, or the steps to build a product, not the parts in the product.

Now second hand equipment, modified equipment and kits, all intended for radio 
amateurs, are exempt. So a manufacturer could in theory provide an amplifier as 
a 'kit'. That would mean the buyer installing the power transformer and 
soldering the wires to it, rather than having them on plugs and sockets. 
Perhaps provide the SO239 output socket not installed but with the hardware to 
do it. There is even an argument that a non-compliant amplifier with an SO239 
socket as standard would become a modified and thus exempt device if the socket 
was changed to an N type by the owner before importation......
Fortunately, the volume of business that amateur radio represents in the EU is 
small enough that Brussels haven't got around to excess regulation of it - yet!
