Re: Requirements for Software to be CE Mark Compliant - IEC 62304 Medical Device Soft
I think unless you determine volunteer compliance to any standard apart from ISO13485 and ISO14971 in your quality policy, all you need to be in place is your view over your compliance with the essential requirements defined in the corresponding MDD.
One angle looks correct from your auditor is that you have nothing to do with IEC 60601 due to that is for electrical programmable devices, whereas your software only device is not that kind.
Cheers!
ps.: if you really keen on this 62304 compliance a food of though would be to list all of the requirements in this standard and next to them list the things you have in place that addresses the particular requirement.
Again, your compliance with essential requirements are the one is required.
