This document 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 document 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 document 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.In special circumstances, where specified in national building regulations, there can be a need to subject the protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in Annex C.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 structures, membranes and fittings.This documentapplies only where there is a gap and a cavity between the horizontal protective membrane and the structural building member. Otherwise, the test methods in EN 13381-3, EN 13381 4 or EN 13381-5, as appropriate, apply.Tests are intended to be carried out without additional combustible materials in the cavity.Annex A gives details of assessing the performance of the ceiling when exposed to a semi-natural fire.

This 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 EN 13381-8 unless all the testing is carried out in accordance with Annex B using a minimum length of 2 000 mm. If testing to EN 13381 4 or EN 13381-8 has not been carried out then loaded testing shall be carried out in accordance with Annex B.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 or any other cold formed bar used as reinforcement in concrete construction.For other solid bar geometries such as oval or triangular cross section, these should 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 130 mm 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 should 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 provided they have been tested in the same orientation.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 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 as given in EN 13381-4.This standard also provides the assessment procedure, which prescribes the analysis of the test data and gives guidance on the procedures to undertake interpolation.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 should only be used for horizontal bars when the data has been corrected in accordance with Annex C.This standard gives the fire test procedures, carried out to provide data on the thermal characteristics of the fire protection system, when exposed to the standard temperature/time curve specified in Clause 5.1.1 of 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 application of the results to different steel types and sizes over the range of thicknesses of the applied fire protection system tested.

This European Standard specifies requirements and test methods for rain caps that are used as components, subject to flue gas, in order to prevent rain entry into the chimneys. Rain caps already tested together with system chimney products or other chimney components, e.g. terminals, are not covered by this standard. Rain caps incorporating a bird guard are also included. It also specifies the requirements for marking, manufacturers’ instruction, product information and evaluation of conformity.
