Dear all,
I have a recurring discussion regarding whether MOOP or MOPP are required for accesible parts per 8.4.2 b).
Some people say: These parts have a chance to be connected to the patient indirectly via the operator, hence MOPP have to be applied (but still with touch current limits).
In my understanding that is wrong: MOPP have to applied only to applied parts or to parts that have to be treated as such (per cl. 4.6). But those parts fall under cl. 8.4.2 a) (patient leakage and auxiliary currents).
What do you think, is the follwoing a correct summary?

- Applied part or treated as such:
-> Cl. 8.4.2 a) (Patient leakage, auxiliary currents) and cl. 8.5.1.2 (MOPP) apply
- Accessible part with direct/indirect patient connection via operator possible:
-> Cl. 8.4.2 b) (Touch currents) and cl. 8.5.1.3 (MOOP) apply
- Accessible part only to the operator:
-> Above 42,4Vp / 60Vdc and E>240VA*60s or stored E>[email protected]>2V: Cl. 8.4.2 b) (Touch currents) and cl. 8.5.1.3 (MOOP) apply
-> Else: Cl. 8.4.2 c) (No MOP) applies
