European Technical Assessment is necessary to enable a manufacturer of a construction product to draw up a declaration of performance for a construction product which is not covered or not fully covered by a harmonised standard.

Article 26(2) of Regulation (EU) No 305/2011 establishes requirements for the content of the European Technical Assessment. Since the principles for the applicable factory production control shall be set out in the respective European Assessment Document (EAD), the European Technical Assessment should contain only such technical details as deemed necessary in these principles within the EAD to be defined at that level for the implementation of the system of assessment and verification of constancy of performance.

The presentation of the technical description of the product in question should be defined flexibly enough in the format of the European Technical Assessment, given the wide variety of construction products concerned.

Sufficient flexibility should also be allowed for the presentation of the performance of the product in the European Technical Assessment, to enable the manufacturer to declare fluently and accurately such performance in his declaration of performance which is based on that assessment.

In order to protect confidential technical information on the product, the manufacturer should be able to indicate to the responsible Technical Assessment Body which parts of the product description is confidential and may not be disclosed together with the European Technical Assessment. Confidential information should be included in separate Annexes to those European Technical Assessments.

In order to enhance the efficiency of the Internal Market and competitiveness of the European construction sector as a whole, European Technical Assessments should be able to be issued as soon as possible for manufacturers requesting them,
