Chris, Please be aware that I speak here of general safety principles and not what is required specifically by EN 60065...
>From a safety perspective, what does it matter if the fuse in question is down stream of another over-current protective device? Presumably, if the fuse were to be replaced by one of an incorrect value then the consequence (in the event of a fault in the equipment, of course) would be some sort of hazard? If the effect of replacing the fuse with an incorrect type would be damaged equipment but not a safety hazard, then you are talking performance and not safety. You do not say if your non-IEC 60127 fuse is accessible by end-users or not, or is replaceable without a tool or not. This maters because when a fuse can only be replaced by a service person (because of its location or because you need a soldering iron etc) it is generally considered likely that the service person will check the service manual for details of the correct type and rating; and then fit the correct type. However, if the fuse can be fitted by a user then a higher degree of information is needed - hence the need to mark the value next to the fuse. I hope that if nothing else the above has provided you with a touchstone by which you can judge your situation.
