MATERIAL'S REACTION TO FIRE (EN 13823:2010)
Europe's testing and classification system for building products, which form the basis of the CE marking. Classification of wood products according to EN13501-1:2007+A1:2009 involves initial typing tests according to test method EN13823:2010 for Euro classes B and C and specific for each type of wood as well as including mounting conditions, e.g. mounting on A2 substrate with or without air gap, or backing substrate of D-s2, d0 with or without air gap and so on. The test result is based on the classification of the product/wood classification according to classification standard EN13501-1:2007+A1:2009 within performance groups B, C, D, F. Please note that the stipulations of construction documents shall not be in accordance with the classification standard EN13501-1, against harmonised product standards where the EU imposes a CE marking of solid wood and wood-based discs according to EN14915:2013 or EN13986:2004+A1:2015. Fire class B and C regulations require mandatory CE marking and a performance declaration, known as DoP.
Common untreated wood is classified as D-s2, d0 according to CWFT. A large consideration is that application with another substance e.g. linseed oil, mineral oil may mean that the wood no longer reaches D-s2, d0, in the worst case, the product can be classified down to Euro class F. When this or a similar product is prescribed as D-s2, d0, we recommend that downstream users request document that prove D-s2, d0. More often, we hear how this type of product was painted in a workplace with fire protection paint, which is highly questionable protection as the fire protection drips from the panel when the oil melts, resulting in the paint falling to the ground.
IT IS IMPORTANT to understand that the fire report and classification report do not provide a certification of the product and the manufacturer's process. Classification of the product only reflects the performance of the product, while certification, e.g. CE marking, is the official driving license where the entire manufacturing chain and control system are included via AVCP system 1 by notified body. CE marking, on the other hand, does not mean that national building regulations are complied with, this must be checked against BBR and PBL.
PLEASE REMEMBER that industrial impregnated woods are always subject to compulsary requirements for CE marking and performance declarations when Euroclasses B and C are marketed. Fire protection impregnated wood products without CE marking may not be marketed nor used in accordance with EU Building Products Regulation 305/2011.
