Many thanks to Jon / Chris et. al for the responses. This advice was directly on target. For compliance with the Motor Vehicle EMC Directive, Informative Annex B Section B.2.4 of 301 489-1 v1.6.1 :2005 points out the applicable section of the Directive that requires testing for conformance to that Directive [and the special conditions of exclusions]. Testing is done per ISO 7637-2. It appears that Section 8.3 of the 301 489-1 v1.6.1 also has requirements for use of the AMN in CISPR 25:2002 in any case [no exclusions] to the limits in Section 8.3. Since the 2005 version of 301 489-1 is not yet listed on the OJ, I wasn't familiar with it. Best regards, Mac

The applicable EMC standard per the R&TTE Directive would be 301 489-5, which basically falls back on 301 489-1 without any special conditions. The way I read 301 489-1 is that DC conducted emissions are to be tested per EN 55022 for AC/DC power adapters at the AC mains for equipment with DC cables < or = 3m or at the DC power port if the manufacturer declares the length of the cord to be over 3m. Neither of these are true in this case, so I don't believe that DC conducted emissions are applicable. However, I have never researched this before and am open to the fact that I am missing something. The engineer has gotten information from another source stating that the charger must be tested to EN 55022 for DC conducted emissions. Does anyone out there know if this is accurate? If so, what kind of AMN would you recommend to measure DC conducted emissions? If this is the case, can you also direct me to the applicable standard that calls out EN 55022 or help me understand why it is applicable if my understanding of 301 489 is incorrect?
