Hi Tony, not being a European, I'm not sure I can advise on the legal requirements. Had it been me assessing what I would do, I would treat the charging as another mode of operation. In this mode, what tests should apply?
All the tests you suggested for sure, and I'd include the voltage dips too. I can see eliminating some of the tests if were battery powered devices and non-chargeable. But as they plug in all apply. This indicates one of my huge criticisms of the CE mark, i.e. it's an excuse not to build a rugged product. I would check the Wall wart too: the ones I have tested have failed miserably, because they are tested by the manufacturer under conditions that favor them. Or the mark is just applied.... MHO, Cheers, Derek.

The trackers are powered by built-in rechargeable cells which are re-charged as required using a standard off-the-shelf plug-in DC wall-wart (which we supply) that has it’s own EMC & Safety approvals from the manufacturer(s). We test Radiated Immunity, Rediated Emissions and ESD on the main unit. I am getting conflicting advice about whether or not we should EMC test (or assess) the following: Conducted Emissions Conducted Immunity Surges Fast Transients. Or even the whole lot, including the radiated emissions & immunity and ESD in charging mode? None of these are applicable for portable equipment under EN 301 489 but I am getting conflicting advice – some say no need to test, some say as it’s plugged in for charging, it should be tested. Help! Opinions and advice most welcome.
