✦ Synopsis
In the harmonization of the European test codes in the context of preventive 5re-protection techniques for buildings, the single 6ame source test is to be adopted as a European test method. This method is used to evaluate the 5re behaviour of a building material subjected to an impingement by a small 6ame, e.g. the 6ame of a match. The technique is used to provide evidence in the determination of whether a building material may be assigned the Euroclass E. Building materials that do not meet the requirements of this building material class are designated as Euroclass F.
The Federal Institute of Material Research and Testing (BAM) has looked into the question of whether the design of the 6ame stabilizer of the burner and the use of three di4erent fuel gases (propane, butane and methane) a4ect the assignation of building materials to a Euroclass, particularly the area between Euroclass E and F. The evaluation showed that the minimum thickness timber boards required to meet Euroclass E requirements would be reduced by approximately 10% when butane and an output stabilizer equipped with a punch disc was used. This means that under modi5ed test conditions, certain timber materials previously assigned to Euroclass F would now be designated Euroclass E. Consequently the safety standard regarding 5re protection in buildings may be compromised.
