Today I aim to measure an RCD or two to determine the DC characteristics.
I;d be very interested in any serious blinding you find - so far my rather unscientific testing has not seen anything other than a rise in threshold of about the same as the DC.
I used a 'jammer' from a bench supply of DC with a fully floating output and a couple of wire wound resistors (one to N, one to E, started with 1k ohms and then reduced to mul;tiples of 100 in parallel) to set the current and with a thousand uF or so of C across the DC supply to act as a fault limiters if something unpleasant came down the NE loop.
The actual threshold of the RCD I found a bit variable from shot to shot even without the jammer, and also needed a bank of resisiors as I do not have a ramp tester.

No DoC from these guys just this spec.

Has any forum member asked for a Declaration of Conformity from EV charging equipment manufacturers and received one?
The Type B (or Type A or F plus RDC-DD) would still be required for the EVSE.
I don't think there's a requirement (or need) for upstream devices to be anything more onerous than Type A, as the downstream device detects the DC residual current fault. A few manufacturers have been supplying Type A rather than Type AC for a few years now.
