适用范围：This Part of this European Prestandard specifies a test method to be followed for determining the contribution offire protection systems to the fire resistance of structural timber members.Such fire protection systems include claddings, sprayed fire protection and coatings.The method is applicable to all fire protection systems used for the protection of timber members. These can be fixeddirectly, totally or in part, to the timber member and can include an air gap between the fire protection system andthe timber member, as an integral part of its design.Evaluation of timber constructions protected by horizontal or vertical protective membranes are the subject of ENV13381-1 or ENV 13381-2 respectively.The test method is applicable to the determination of the contribution of fire protection systems to the fire resistanceof loadbearing timber structural members and non-loadbearing parts of the works, including floors, roofs, walls,beams and columns. It is also applicable to timber structural members incorporating insulating materials betweenthe timber members, e.g. between timber joists in floor constructions.The test method and its assessment procedure is designed to permit direct application of the results to cover a rangeof thicknesses of the applied fire protection material.This European Prestandard contains the fire test which specifies the test to be carried out to determine the abilityof the fire protection system to delay the temperature rise throughout the timber member, to determine the abilityof the fire protection system to remain coherent and fixed to the timber member and to provide data of thetemperature profile throughout the timber test member, when exposed to the standard temperature/time curveaccording to the procedures defined herein.In special circumstances, where specified in national building regulations, there can be a need to subject reactiveprotection material to a smouldering curve. The test for this and the special circumstances for its use are detailedin annex A.The fire test methodology makes provision for the collection and presentation of data which can be used as directinput to the calculation of fire resistance of timber members in accordance with the procedures given inENV 1995-1-2.A description of the relationship of this test method and the assessment of the results obtained therefrom toENV 1995-1-2 and guidelines for the use of this test method in accordance with that standard are given in annex B.This European Prestandard also contains the assessment which prescribes how the analysis of the test data shouldbe made and gives guidance to the procedures by which interpolation should be undertaken.The limits of applicability of the results of the assessment arising from the fire test are defined, together withpermitted direct application of the results to different timber constructions over the range of thicknesses of theapplied fire protection system tested.
