Vivier is wrong in one thing. The RCD is not a set of rules. Its a directive (The D means directive) and as a such, each state of the EU can use it the way they like. Thats why its basically useless, because the diferences between very authoritative states like Spain and very "free" (when it comes to boats) states like the Scandinavian is enourmous. Its like living on two different solar systems.
Back to the tests. It should be standard procedure to do tests like this on your own. Not because of some kind of rule but because of common sense. If you dont like getting wet, stay away from the water.
