What is BS EN 13381-9 – Determining fire protection systems to steel beams with web openings about?
BS EN 13381-9 is the ninth part of the multiple series that 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 which may affect the structural performance of the beam.
Note 1: BS EN 13381-9 applies to beams subject to 3- or 4-sided fire exposure.
Note 2: BS EN 13381-9 applies to fire protection materials that have already been tested and assessed in accordance with EN 13381-4 or EN 13381-8. i.e., BS EN 13381-9 cannot be used in isolation.
Note 3: Use of BS EN 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 needs to 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.

Why should you use BS EN 13381-9 - Determining fire protection systems to steel beams with web openings?
BS EN 13381-9 specifies the fire test methodology, which specifies the tests which need to be carried out to provide data on the thermal characteristics of the fire protection system when exposed to the standard temperature/time curve specified.
BS EN 13381-9 also contains the assessment, which prescribes how the analysis of the test data should be made and gives guidance on the procedures which should be undertaken.
Overall, BS EN 13381-9 helps you with the test methods to determine fire protection systems to steel beams with web openings.
