This document describes the test and assessment procedure for determining the contribution of reactive fire protection systems to the fire resistance of solid steel bars used as tension members, when exposed to the standard temperature/time curve specified in EN 1363-1. In special circumstances, where specified in National Building Regulations, there can be a need to subject reactive fire protection systems to a slow heating curve (smouldering fire) as defined in EN 1363-2. The corresponding test and assessment procedure are described in Annex E. The fire protection performance is determined by testing mechanically loaded steel bars in horizontal orientation. Information regarding the testing of additional unloaded specimens is given to assess the influence of the bar orientation and smouldering fire behaviour. The principles of the testing and assessment procedure can also be applied for other section shapes such as angles, channels and flats. This document does not include steel bars used as reinforcement in concrete construction. The document is applicable to steel bars up to a maximum diameter of 130 mm. In the case of rectangular bars, the maximum edge length shall be limited to 130 mm with a maximum aspect ratio of 2:1 against the shorter edge length. The test programme and the assessment are designed to cover: - a range of valid fire protection classification periods; - a range of thickness of the applied reactive fire protection system; - a range of steel bar dimensions and profiles; - a range of specified design temperatures; - a range of load utilisation factors in case of fire; - a range of bar orientation. This document 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. The assessment procedure is used to establish: a) on the basis of data derived from mechanically loaded testing steel bar, any practical constraints on the use of the reactive 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 reactive 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 reactive fire protection system tested.

This document describes the conditioning procedures for test specimens which will be tested according to the European standards for reaction to fire. The rules for the selection of substrates for construction products when carrying out reaction to fire tests are also detailed in this document. This document does not contain requirements for - the pre-drying of test specimens for the non-combustibility test according EN ISO 1182; - methods of cleaning (e.g. washing) and other methods for the assessment of durability aspects, which are dealt with in the relevant product standards.

This document describes test methods and methods for classification of wood and wood-based products for which a stage in the production process results in an improvement of the reaction-to-fire classification in accordance with EN 13501-1 for use in interior and exterior situations (use classes 1, 2, and 3 as defined in EN 335:2013). NOTE The classes of this document are not performance classes and do not give guidance for how long the reaction to fire classification of wood or wood-based product will last. This document applies to - wood and wood-based products (specific wood species, wood treated with preservatives and modified wood, for example thermally and chemically modified wood) that have been treated with fire-retardant chemical(s) applied either by a penetrating process or by a superficial process, such as with a film forming fire-retardant coating. - wood-based products that incorporate fire retardant chemical(s) as part of the production process. This document also covers fire-retardant wood and wood-based products that have a non-fire-retardant coating. Mechanical properties, aesthetic properties, dimensional stability properties, service life and biological durability of fire-retardant wood and wood-based products are not covered by this document. NOTE 2 This document is relevant for, but not limited to, products covered by these products standards: EN 13986, EN 14081-1, EN14374, EN 14915 and EN 16351. NOTE 3 EAD 350865-00-1106 covers fire retardant products (coating) applied in situ.
