DIN EN 13381-7:2014-12

This Part of this European Standard specifies test methods to be followed for determining the contribution of fire protection systems to the fire resistance of structural timber members. Such fire protection systems include claddings, sprayed fire protection and reactive coatings. The method is applicable to all fire protection systems used for the protection of timber members. These can be fixed directly, totally or in part, to the timber member and can include an air gap between the fire protection system and the timber member, as an integral part of its design. Evaluation of timber constructions protected by horizontal or vertical protective membranes are the subject of EN 13381-1 or EN 13381-2 respectively. The test method is applicable to the determination of the contribution of fire protection systems to the fire resistance of loadbearing timber structural members including floors, roofs, walls, beams and columns. This European Standard contains the fire test which specifies the test to be carried out to determine the ability of the fire protection system at a specified thickness to delay the temperature rise throughout the timber member, to determine the ability of the fire protection system at a specified thickness to remain coherent and fixed to the timber member and to provide data for determining the charring rate of the protected test member, when exposed to the standard temperature/time curve according to the procedures defined herein. This European Standard is not appropriated to classify the tested assembly according to EN 13501-2.
