DIN EN 13381-9:2013-04

This European Standard specifies a test and assessment method for determining the contribution made by fire protection systems to the fire resistance of structural steel beam I and H members in the horizontal plane containing openings in the web. This Standard applies to beams subject to 3 or 4 sided fire exposure. This Standard applies to fire protection materials that have already been tested and assessed in accordance with EN 13381-4 or EN13381-8. i.e. prEN 13381-9 cannot be used in isolation. Use of prEN 13381-9 requires the multi-temperature analysis (MTA) derived from EN 13381-4 or EN 13381-8 as the basis for determining thickness for beams with web openings. This MTA shall be carried out on the web and bottom flange separately generating an elemental multi-temperature analysis (EMTA). The bottom flange EMTA may be used as the top flange EMTA when a beam is subject to 4 sided exposure. This European Standard contains the fire test methodology, which specifies the tests which shall be carried out 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.
