Thus, these medical device directives valid until that date will cease to apply:

• Directive on Active Implantable Medical Devices 90/385/EEC (AIMD)
• Directive on Medical Devices 93/42/EEC (MDD)
• Directive on in vitro diagnostic medical devices 98/79/EC (IVDD).

With the entry into force of the IVDR, the dates for transition periods have been partially adjusted:

25 May 2022-26 May 2025
Certificates still issued under the IVDD can remain valid until 26 May 2025; however, all Class D devices placed on the market after 26 May 2025 must be fully compliant with the IVDR.

By 26 May 2026
All Class C devices placed on the market after 26 May 2026 must be fully compliant with the IVDR.

26 May 2027
All class B devices and class A sterile devices placed on the market after 26 May 2027 must be fully compliant with the IVDR.

Continued without change from 26 May 2022
All non-sterile class A devices placed on the market after 25 May 2022 must be fully compliant with the IVDR. All new devices placed on the market must comply with the IVDR.
