Declaration of Conformity, Technical File, Language and Retention Period
Connect every declaration to the corresponding product revision and technical evidence.
Continue with the relevant decision step
Direct answer
Connect every declaration to the corresponding product revision and technical evidence. Drawings, risk assessment, components, software, reports and instructions must support the identity actually supplied. Declaration language and retention obligations follow the applicable product legislation and market; one universal language or period is unreliable.
Decision and evidence
Maintain controlled versions and a market-specific language and retention plan. Review design changes before issuing a new declaration date or distributing translated copies.
Technical basis
The declaration is the manufacturer’s signed legal statement. Product identification, applicable legislation, standards, authorised signatory and technical-file link must be consistent.

Is an English declaration sufficient for every country?
Check language requirements for the declaration and accompanying information in each market. Translation must preserve model, legislation, date and signature meaning. Website language does not determine the destination country. Connect all language copies to the same current declaration version.
Is changing the declaration date sufficient after a product modification?
First assess effects on the technical basis for conformity. Complete necessary further assessment before updating the declaration and related records. Preserve traceability between product revisions and declarations. A new date alone does not address changed designs or legal requirements.
