The 'new' guidelines on interpreting the EMC directive allow for the integration of multiple CE marked products without having to retest the full system. The caveat in that however is that the CE marking must be "relevant". That is, the original CE mark must have been applied based on tests which are equivalent to the environment that you are planning for the system.
The fact that you say the printers "were not designed for these severe spikes..." indicates that they were NOT marked based on relevant standards. You must therefore fully test them in accordance with the appropriate standards as part of your system.

It is an intentional transmitter, so we are getting it type-approved by a notified body, the DRA in the UK. DRA has told us ETS300339 is the relevant product standard. ETS300339 calls for most of the usual emissions and immunity tests such as EN55022 and IEC1000-4-x, but it also calls for testing to ISO7637, an automotive spike and surge immunity standard. The system will ship with a choice of printers that are DC-powered at 12 to 24 volts and that are purchased CE-marked from a reputable printer manufacturer. My question is: do these off-the-shelf printers have to comply with ISO7637 because they are part of this larger system, or can they stand alone with their current CE marking? The printers were not designed for these severe spikes and surges and will likely fail. ------------------------------------------ John Lovell Director of Quality Trimble Navigation Ltd. +408-481-2012 Voice +408-481-8194 FAX john_lov...@trimble.com ------------------------------------------
