Classify the device under Annex VIII before choosing the conformity route. The record should show the applicable rule, duration of use, invasiveness, body contact, active function, software decision impact, medicinal substance or tissue component, sterile or measuring function, and the reason the highest applicable class was selected.
Use the classification to select the conformity assessment route under Article 52 and Annexes IX, X, or XI. Class IIa, IIb, and III devices generally require a notified body. Most class I devices use manufacturer self-declaration, but sterile class I devices, class I devices with a measuring function, and reusable surgical instruments need notified-body involvement limited to sterility, metrology, or reuse controls. Confirm whether the body is designated for the device scope and whether the application, contract, audit, technical-documentation assessment, surveillance, and certificate records are complete.
