EOTA TRs initially were developed as supporting reference documents to European Technical Approval Guidelines (ETAGs). They could also be applied in cases where a common understanding about the assessment methods of a construction product was found by the Approval Bodies (Art. 9 (2) of the Directive 89/106/EEC (CPD)), or to an EOTA Comprehension Document, as far as reference was made therein. They are also developed within the frame of the Regulation (EU) No 305/2011 (CPR).
Where engineering knowledge and technical experience is developing, especially through assessment work and research activities, such reports could be amended and updated. EOTA TRs support the assessment work of TABs and the EAD development in EOTA.
EOTA TRs are adopted by the EOTA Technical Board. If containing assessment methods and criteria for assessing the performance of construction products in relation to their essential characteristics they are subject to consultations of concernded stakeholders and the European Commission.
