Plain language

Technical documentation is your proof file — the collection of records that shows regulators and auditors exactly how your product meets all the CRA requirements. You must prepare it before launch, keep it updated throughout the product's support period, and store it for at least 10 years. It should include your design description, risk assessment, test reports, a copy of the EU DoC, details of how you determined the support period, and lists of standards applied.

Legal text

The technical documentation shall contain all relevant data or details of the means used by the manufacturer to ensure that the product with digital elements and the processes put in place by the manufacturer comply with the essential cybersecurity requirements set out in Annex I. It shall at least contain the elements set out in Annex VII.

Article 31(2):

The technical documentation shall be drawn up before the product with digital elements is placed on the market and shall be continuously updated, where appropriate, at least during the support period.
