DIN EN 13381-8:2013-08

This European Standard specifies a test method for determining the contribution made by applied reactive fire protection systems to the fire resistance of structural steel members, which can be used as beams or columns. It considers only sections without openings in the web. It is not directly applicable to structural tension members without further evaluation. Results from analysis of I- or H-sections are directly applicable to angles, channels and T-sections for the same section factor, whether used as individual elements or as bracing. This standard does not apply to solid bar or rod. This document covers fire protection systems that involve only reactive materials and not to passive fire protection materials. The evaluation is designed to cover a range of thicknesses of the applied fire protection material, a range of steel sections, characterized by their section factors, a range of design temperatures and a range of valid fire protection classification periods. This European Standard describes the fire test procedures, which are carried out to determine the ability of the fire protection system to remain coherent and attached to the steelwork, and to provide data on the thermal characteristics of the fire protection system, when exposed to the standard temperature/time curve specified in EN 1363-1. This standard differs from DIN EN 13381-8:2010-09 as follows: a) normative references have been updated; b) a change has been made to the test method to introduce measures allowing loaded beams to reach a deflection of L/30; c) in addition, the graphical assessment method now includes a point to point method of constructing lines and a new virtual data point related to furnace temperature. d) Annex G has been deleted; e) the figures have been editorially revised. The document has been prepared by CEN/TC 127 "Fire safety in buildings". the secretariat of which is held by BSI (United Kingdom). The committee responsible for this standard is Working Committee NA 005-52-02 AA "Brandverhalten von Baustoffen und Bauteilen - Bauteile (SpA zu CEN/TC 127/WG 1) sowie Teilbereichen von CEN/TC 127/WG 7 und ISO/TC 92/SC 2" ("Fire performance of building materials and building elements - Building elements (Mirror Committee of CEN/TC 127/WG 1 and parts of CEN/TC 127/WG 7 and ISO/TC 92/SC 2)").
