BS EN 1366-3-2009服务装置用耐火试验.渗透密封件

This Part of EN 1366 specifies a method of test and criteria for the evaluation (including field ofapplication rules) of the ability of a penetration seal to maintain the fire resistance of a separatingelement at the position at which it has been penetrated by a service. Penetration seals used to sealgaps around chimneys, air ventilation systems, fire rated ventilation ducts, fire rated service ducts,shafts and smoke extraction ducts are excluded from this standard except for mixed penetrationseals. The fire resistance of those services itself cannot be assessed with the methods described inthis standard.Supporting constructions are used in this standard to represent separating elements such as walls orfloors. These simulate the interaction between the test specimen and the separating element intowhich the sealing system is to be installed in practice.This European Standard is used in conjunction with EN 1363-1.The purpose of this test described in this standard is to assess:a) the effect of such penetrations on the integrity and insulation performance of the separatingelement concerned;b) the integrity and insulation performance of the penetration seal;c) the insulation performance of the penetrating service or services, and where necessary, theintegrity failure of a service.No information can be implied by the test concerning the influence of the inclusion of suchpenetrations and sealing systems on the loadbearing capacity of the separating element.It is not the intention of this test to provide quantitative information on the rate of leakage of smokeand/or hot gases or on the transmission or generation of fumes. Such phenomena are only to benoted in describing the general behaviour of test specimens during the test.This test is not intended to supply any information on the ability of the penetration seal to withstandstress caused by movements or displacements of the penetrating services.The risk of spread of fire downwards caused by burning material, which drips through a pipedownwards to floors below, cannot be assessed with this test.Explanatory notes to this test method are given in Annex H.All dimensions given without tolerances are nominal ones unless otherwise stated.
