As I understand it, the (iv) is the usual voltage measurement and the (v) opens all Iive conductors plus the protective conductor to the vehicle in not more than 12ms in the event of current in that conductor exceeding 18mA.
(iv) requires disconnection of PE as well as L & N too.
(v) seems to leave the door pen for any future bright ideas - I'm not sure why they claim compliance with (v) as well, as the basic operation seems to be covered by (iv).
I'm still waiting for reports of false triggering of the c.p.c. current monitring - e,g. if the car door touches some earthed metalwork and a small diverted N current flows to Earth...
