Technical Assessments

Definition

A European Assessment Document (EAD) is a document containing at least:

  • a general description of the construction product;
  • the list of essential characteristics, relevant for the intended use of the product as foreseen by the manufacturer and agreed between the manufacturer and the organisation of TABs;
  • the methods and criteria for assessing the performance of the product in relation to those essential characteristics
  • principles for the applicable factory production control to be applied.

Procedure

The European Technical Assessment (ETA) shall be issued by a Technical Assessment Body (TAB) on the basis of a European Assessment Document adopted by the European Organisation for Technical Assessment (EOTA).

A request for a European Technical Assessment by a manufacturer for any construction product not covered or not fully covered by a harmonised standard and for which the performance in relation to its essential characteristics cannot be entirely assessed according to an existing harmonised standard can be addressed to a Technical Assessment Body (TAB) designated in the product area in question (see TABs in NANDO).

An updated list of references of the final EADs will be published by the Commission in the Official Journal of the European Union.

The European Technical Assessment is issued on basis of a EAD and shall include:

  • the performance to be declared, by levels or classes, or in a description, of those essential characteristics agreed by the manufacturer and the TAB receiving the request for the European Technical Assessment for the declared intended use, and
  • technical details necessary for the implementation of the system of assessment and verification of constancy of performance.
