How an EAD is developed?

The development of an EAD follows the definition of a work and assessment programme in cases a manufacturer has requested a European Technical Assessment (ETA) of a construction product and no appropriate basis for the technical assessment of such a product yet exists.





The Technical Assessment Body (TAB) which has received the ETA request will define the work and assessment programme taking into account the essential characteristics, relevant for the intended use and based on the agreement between the manufacturer and the TAB.



In case no appropriate basis for the technical assessment of a product exists, the subject of the ETA request and the work and assessment programme will be discussed in EOTA.

When the work and assessment programme will be executed, in parallel and beside to the ETA process the EAD will be drafted by the Technical Assessment Body (TAB) which has received the request for an ETA (so called RTAB).

The draft EAD will be discussed within EOTA. Those Bodies designated for the relevant product area(s) and/or horizontal or ad hoc working groups will participate in the development process as well. The development procedure is managed by the RTAB.

EOTA informs the European Commission about the work program. In most case, this information also contains information on the assessment programme. From that moment on, the development process of an EAD in general should not exceed six months. The European Commission is involved in the development from the moment of the 1st draft EAD, which also initiates the adoption phase. The final draft EAD is agreed upon consensus of the Technical Assessment Bodies (TABs), adopted in the EOTA Technical Board and submitted for observations to the European Commission. Consultation periods are defined in the Regulation (EU) 305/2011 and are further detailed in the Consistency System Manual of the EOTA Internal Regulations.

The manufacturer is fully involved in the development and adoption process of the EAD. The TAB and EOTA bear the full cost of the development of such an EAD. Complementary, the EAD development is financed through EU grants awarded to EOTA.

References of the final EADs are cited in the Official Journal of the European Union (OJEU), if an ETA is issued. EOTA ensures that EADs are kept publicly available.

TABs in EOTA and the European Commission are committed to implement smart procedures. The development process is regularly evaluated and adjusted, if necessary.


In brief

EAD development procedure: consultations and adoption

  1. Consultation amongst TABs on the ETA request and initial work and assessment programme – 1 month
  2. Consultation amongst TABs on the final work programme, if needed – 2 weeks
  3. Consultation amongst TABs and EC on a 1st draft EAD – 1 month
  4. Consultation of manufacturer on final draft EAD – 15 working days
  5. Consultation of EC on adopted draft EAD – 15 working days
  6. Adoption of final EAD, if needed – 2 weeks in written consultation

Steps at the Publication phase of final EADs 

  1. Adjustments of adopted EADs, if appropriate, based on experience gained
  2. Editing of final EADs by RTABs and EOTA
  3. Translation of EAD titles in all official EU languages
  4. Announcement of EADs to EC for publication in the OJEU
  5. Publication of EAD references in the OJEU by EC – 2nd Friday of a month
  6. Final editing and publication of EAD text by EOTA

Procedures which may delay the publication of a final EAD

  1. Consultation of Member States on delegated acts for AVCP decisions and publication
  2. Consultation of Member States on agreements on classes of performances or threshold levels and respective agreements
  3. Need to develop a new test method
