EMDN S90: Devices for Sterilisation (Excluding Cat. D - Z) - Various

Complete hierarchy for EMDN group S90 in category S (Sterilisation Devices (Excluding Cat. D - Z)): 8 terminal codes, EMDN v2026. Terminal codes are the ones accepted in a EUDAMED device record.

Registered classes, as of 8 Sep 2026. For each code with at least 20 registrations under a legislation, the chip shows how devices registered in EUDAMED under that code are classed, counted once per primary UDI-DI and kept separate for each legislation. It is not a determination. The class of a device comes from the MDR and IVDR classification rules for its intended purpose. MDD and IVDD classes are the directive classification and can differ from the class the same device would have under MDR or IVDR.

How S90 is structured

8
terminal codes, selectable in a device record
1
branch heading, not selectable
5
name a specific device type
38%
fallback entries: Other and Accessories

The Devices for Sterilisation (Excluding Cat. D - Z) - Various branch runs 2 levels deep. One entry below is a branch heading that groups other codes rather than naming a device, so a classification has to resolve all the way down to one of the 8 codes marked terminal.

2 terminal codes are “- Other” entries and 1 is an “- Accessories” entry, 38% of the branch. An “- Other” code is the residual slot for devices its siblings do not name, so it is worth ruling out every specific sibling before settling on one.

Frequently asked questions

Which S90 codes can be used in a EUDAMED device record?
8 of the 9 codes listed under S90 (Devices for Sterilisation (Excluding Cat. D - Z) - Various) are terminal and can be selected. The other 1 is a branch heading that cannot.
How deep is the S90 hierarchy?
The S90 branch runs 2 levels below the group code.
How many S90 codes are catch-all entries?
2 terminal codes under S90 are "- Other" entries and 1 is an "- Accessories" entry, 38% of the branch. The remaining 5 name a specific device type.

Not sure which level to stop at, or which of two plausible codes to submit? The guide to choosing an EMDN code walks the decision level by level, with a worked example and the mistakes that get a EUDAMED registration rejected.
