Technical file
A technical file is a set of documents that describes a product and can prove that the product was designed and according to the requirements of a quality management system.
All products that have a CE mark must have a technical file which must contain the information that proves that the product conforms with the EU directives for CE-marked products. EU enforcement authorities may demand a copy of the technical file for many years after the last product was made. Customers do not usually have access to the technical file.
