Projekta Nr.prEN 13381-10
NosaukumsThis European Standard specifies a fire test method and an assessment procedure for determining the contribution of fire protection systems to the fire resistance performance of circular and rectangular steel bars used as tension members. This Standard applies to fire protection materials that have already been tested and assessed in accordance with EN 13381-4 or EN13381-8 unless all the testing is carried out in accordance with Annex B using a minimum length of 2000mm. For other section shapes such as angles, channels and flats reference should be made to EN 13381-4 and EN 13381-8. This standard does not include steel bar used as reinforcement in concrete construction. For other solid bar geometries such as oval or triangular cross section, these shall be subject to a separate test package in accordance with the principles of Clause 5 of this Standard. Fire protection performance is determined by testing of unloaded tension members, although additional loaded test evidence may be required for certain product types subject to certain conditions specified in the Standard. The method is applicable to all fire protection systems used for the protection of solid bar up to a maximum diameter of 130mm and includes sprayed fire protection, reactive coatings, cladding protection systems and multi-layer or composite fire protection materials. In the case of rectangular bar the maximum side length shall be limited to 130mm with a maximum aspect ratio of 2:1 against the shorter side length. For dimensions greater than 130mm it is appropriate to use rectangular or circular hollow sections tested and assessed in accordance with EN 13381-4 and EN 13381-8. The evaluation is designed to cover a range of thicknesses of the applied fire protection material, a range of steel bar dimensions, a range of specified temperatures and a range of valid fire protection classification periods The test method is applicable to fire protection systems which are intimately in contact with the bar, or which include an airspace between the bar and the protection system. This standard also provides the assessment procedure, which prescribes how the analysis of the test data shall be made and gives guidance on the procedures by which interpolation shall be undertaken. This Standard caters for testing in both vertical and horizontal orientations. Results from horizontally orientated bar may be applied to any orientation, whilst results from vertically orientated bar shall only be used for horizontal bars when the data has been corrected in accordance with Annex C. This standard gives the fire test procedures, 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. The assessment procedure is used to establish: a) on the basis of data derived from testing steel bar, any practical constraints on the use of the fire protection system under fire test conditions (the physical performance); b) on the basis of the temperature data derived from testing steel bar the thermal properties of the fire protection system (the thermal performance). The limits of applicability of the results of the assessment arising from the fire test are defined together with permitted direct application of the results to different steel types and sizes over the range of thicknesses of the applied fire protection system tested.
