Yes I saw that page also on the web.
I got the standard now and I saw that the standard says so.
My interpretation is that manufacturers shall look at the product standard they have. However 60601 and 61010 refers to IEC60990 if I got it correctly as a guidance.
Found also a new document telling the following:
Resistors and capacitors used need to have a tolerance of +/- 1.0 % or individually selected for correct value by measurement.
Hard to find such capacitors
