MOOP and MOPP
New IEC60601-1 3rd version catagorized into MOOP and MOPP. IED60601-1 is the global medical equipment standard. The concept of Means of Protection (MOP) lead to IEC60601-1 3rd, which divided into MOPP(Means of Patient Protection) and MOOP(Means of Operator Protection).
According to it, Some countries reorganized to their own standards, like
USA: ANSI/AAMIES 60601-1:2005
EU: EN60601-1: 2005
Canada: CSA-C22.2 No. 60601-1:08
The difference between MOOP and MOPP in IEC60601-3rd edition for medical switching power supply. We listed the differences as below:
classifications | isolation | Creapage/clearance | insulation |
1*MOOP | 1500VAC | 2.5mm/2mm | basic |
2*MOOP | 3000VAC | 5mm/4mm | double |
1*MOPP | 1500VAC | 4mm/2.5mm | basic |
2*MOPP | 4000VAC | 8mm/5mm | double |
When equipment is used at laboratory and not touch patient, it's enough for power supply to meet 2*MOOP. Meanwhile, the highest level 2*MOPP can be used for patients.
