            COMMISSION DELEGATED REGULATION (EU) 2017/2293
of 3 August 2017
         
on the conditions for classification, without testing, of cross laminated timber products covered by the harmonised standard EN 16351 and laminated veneer lumber products covered by the harmonised standard EN 14374 with regard to their reaction to fire
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EU) No 305/2011 of the European Parliament and of the Council of 9 March 2011 laying down harmonised conditions for the marketing of construction products and repealing Council Directive 89/106/EEC (1), and in particular Article 27(5) thereof,

Whereas:







(1)


A system for classifying the performance of construction products with regard to their reaction to fire was adopted by Commission Delegated Regulation (EU) 2016/364 (2). Cross laminated timber products and laminated veneer lumber products are construction products to which that Delegated Regulation applies.












(2)


Tests have shown that cross laminated timber products covered by the harmonised standard EN 16351 and laminated veneer lumber products covered by the harmonised standard EN 14374 have a stable and predictable performance concerning their reaction to fire provided that they fulfil certain conditions regarding the form of the product as well as its installation, mean density and thickness.












(3)


Cross laminated timber products covered by the harmonised standard EN 16351 and laminated veneer lumber products covered by the harmonised standard EN 14374 should therefore be deemed to satisfy a certain class of performance for reaction to fire established by Delegated Regulation (EU) 2016/364 without testing being required, where they fulfil those conditions,





HAS ADOPTED THIS REGULATION:



Article 1
Cross laminated timber products covered by the harmonised standard EN 16351 and laminated veneer lumber products covered by the harmonised standard EN 14374 which fulfil the conditions set out in the Annex shall be deemed to satisfy the classes of performance indicated in the Annex without testing.


Article 2
This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.




This Regulation shall be binding in its entirety and directly applicable in all Member States.
Done at Brussels, 3 August 2017.


For the Commission


The President
