BS EN 13381-3:2015 PDF Download

BS EN 13381-3:2015 is a European Standard that provides a test method for determining the contribution of fire protection systems to the fire resistance of structural concrete members. This standard applies to various types of concrete members such as slabs, floors, roofs, and walls, including integral beams and columns. The concrete can be of different strength classes and densities, and it should contain steel reinforcing bars.

The test method outlined in the standard is applicable to all types of fire protection materials used for concrete members, including sprayed materials, reactive coatings, cladding protection systems, and composite fire protection materials. The tests aim to determine the ability of the fire protection material to remain fixed and coherent to the concrete member during exposure to the standard temperature time curve.

The standard also includes provisions for testing under special circumstances, such as subjecting the protection material to a smoldering curve, as specified in national building regulations. The results of the fire tests can be used as input for calculating the fire resistance of concrete members according to the procedures outlined in EN 1992-1-2.

Additionally, the standard provides guidance on analyzing the test data and performing interpolation. It defines the limits of applicability for the assessment results, including the permitted direct application to different concrete structures, densities, strengths, thicknesses, and production techniques. It should be noted that this standard is not applicable to structural hollow concrete members.
