Types of MDR Technical Files by Device Class
The main types of MDR technical files follow the device class, the classification rule and the conformity route. EU MDR 2017/745 requires technical documentation for each device, in proportion to its risk. This page explains how the file changes for class I, IIa, IIb and III devices and for special device categories.
What Are the Types of MDR Technical Files?
The MDR does not give manufacturers a fixed list of file types. It does, however, set the content of technical documentation in Annexes II and III, the classification rules in Annex VIII and the conformity assessment routes in Article 52. Together, these create the practical types of MDR technical files used in CE marking projects.
The type of file you need depends on how the device is classified and how it will be assessed. A non-sterile class I device can usually follow self-declaration. A class III implant needs much deeper evidence and notified body review. Every type still follows the same MDR technical documentation requirements in Annexes II and III. For the wider overview, see our medical device technical documentation guide.
How Do Technical Files Differ by Device Class?
1
Class I
The manufacturer draws up the technical documentation and issues the EU declaration of conformity. A notified body is involved only for sterile, measuring or reusable surgical instrument aspects.
2
Class IIa
The file supports notified body assessment. Technical documentation is assessed for at least one representative device in each category of devices.
3
Class IIb
The notified body assesses technical documentation for at least one representative device per generic device group. Most class IIb implants are assessed device by device.
4
Class III
The notified body assesses the technical documentation under Annex IX, or uses the Annex X and Annex XI route. Clinical evidence is normally the most demanding part of the file.
Device characteristics also shape each file. Active, non-active, software, sterile, measuring, reusable and implantable devices each bring their own evidence needs. Examples include electrical safety and software validation, sterilisation validation, metrological evidence and reprocessing validation.
Which Devices Need a Special Type of Technical File?
- Special rule devices: Rules 14 to 22 can change the class because of medicinal substances, contraception, disinfection, tissues or cells, nanomaterials, inhalation, absorbed substances or closed loop functions.
- Systems and procedure packs: Article 22 usually requires a statement rather than a new CE mark. See our guide to systems and procedure packs.
- Custom-made devices: Annex XIII applies, with an Article 52(8) conformity route for class III custom-made implantable devices.
- Investigational devices: Articles 62 to 81 set out the requirements for clinical investigations.

How Do You Identify the Right Technical File?
- Define the deviceRecord the intended purpose, indications, site of application, duration of use and how the device works.
- Classify the deviceApply the Annex VIII rules, and document the rule and your reasoning. Use the highest applicable class where more than one rule applies.
- Find the conformity routeUse Article 52 and the table above to identify the route and the notified body’s role.
- Plan the fileList the Annex II and Annex III content using the technical documentation table of contents, including evidence for active, sterile, software and other features.
- Check for groupingDecide which variants can share a file, and record why. Different intended uses, classes, materials or designs often need separate files.
- Review before submissionUse our MDR technical documentation checklist to find missing documents.
Ready-made structures can save time. Our MDR technical file templates are organised by class and special rule, and our MDR procedures and templates support the related QMS documents.
How Does the Evidence Change Between Types of MDR Technical Files?
Risk and benefit
Every file needs risk management and a benefit-risk conclusion. The depth grows with the risks, intended use and novelty of the device.
Clinical evidence
Every class needs clinical evaluation in line with Article 61. Higher-risk and implantable devices usually need stronger data, and may need clinical investigations.
Testing
Evidence depends on the device. It may include biocompatibility, electrical safety, software validation, sterilisation, stability and shelf life.
Post-market documents
Annex III applies across classes. Class I devices use a PMS report, while class IIa, IIb and III devices use a PSUR.
This is why two devices of the same class can still need different types of medical device technical documentation. A sterile single-use device and a software device may share a risk class, but much of their evidence will be different. Treat the class as a starting point, then add the evidence your specific device needs.
Choosing the wrong file type can cause rework later. It may affect the conformity route, the notified body’s scope and the time needed for testing, so confirm the type before you start writing.
Types of MDR Technical Files: Common Questions
How many types of MDR technical files are there?
The MDR does not set a fixed number. This page groups them by device class, rule and conformity route in 27 rows, which is a practical way to choose the right file.
Does a class I device need a technical file?
Yes. Manufacturers of class I devices must draw up technical documentation under Annexes II and III before issuing the EU declaration of conformity.
Can several devices share one technical file?
Sometimes. Devices can only be grouped when this is justified. Differences in intended use, class, materials or design often require separate files.
