DIN EN 13381-1:2014-12

This European Standard specifies a test method for determining the ability of a horizontal protective membrane, when used as a fire resistant barrier, to contribute to the fire resistance of standard horizontal structural building members as defined in 6.4.2. Test of horizontal protective membrane installed under a specific non-standard floor should be tested according to EN 1365-2. This European Standard contains the fire test which specifies the tests which are carried out whereby the horizontal protective membrane, together with the structural member to be protected, is exposed to a fire test according to the procedures defined herein. The fire exposure, to the temperature/time curve given in EN 1363-1, is applied from below the membrane itself. The test method makes provision, through specified optional additional procedures, for the collection of data which can be used as direct input to the calculation of fire resistance according to the processes given within EN 1992-1-2, EN 1993-1-2, EN 1994-1-2 and EN 1995-1-2. This European Standard also contains the assessment which provides information relative to the analysis of the test data and gives guidance for the interpretation of the results of the fire test, in terms of loadbearing capacity criteria of the protected horizontal structural member. This European Standard has been prepared by Technical Committee 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)" ("Reaction to fire of building materials and building components - Building components (national mirror committee for CEN/TC 127/WG 1 and sub-sections of CEN/TC 127/WG 7 and ISO/TC 92/SC 2")) at DIN.
