Inžinerinių tinklų įrenginių atsparumo ugniai bandymai. 14 dalis. Viename paviršiuje esančių angų sandarinimo priemonės

This part of the EN 1366 series specifies a method of test and criteria for the evaluation (including field of direct application rules) of the ability of a partial penetration seal to maintain the fire resistance of a separating element at the position at which it has been penetrated by a device or devices that passes through one face of the element only. Partial penetration seals are used to seal apertures for electrical sockets, downlighters, media devices, cables and any item which requires an opening to be made in one face of the element of construction but does not include a device which passes through both faces. Supporting constructions are used in this part of the EN 1366 series to represent separating elements such as walls or floors. The supporting construction shall be a system that has been subject to a fire test in accordance with one of the following standards: EN 13381 1 for horizontal membranes, EN 13381 2 for vertical membranes, EN 1364 1 or EN 1365 1 for walls, EN 1366 3 for walls based on a standard supporting construction, or EN 1364 2 or EN 1365 2 for floors. This is referred to throughout this document as the applicable test standard for the supporting construction. This part of the EN 1366 series is used in conjunction with EN 1363 1. The purpose of a test described in this part of the EN 1366 series is to assess the integrity and insulation performance of the partial penetration seal, of the partially penetrating service(s) or device(s) and of the separating element in the surrounding area of the partial penetration seal. Where partial penetration seals are installed in loadbearing elements, it is possible that the loadbearing capacity is also considered. It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes. Tests in accordance with this part of the EN 1366 series are not intended to supply any information on the ability of the partial penetration seal to withstand stress caused by movements or displacements of the penetrating devices. The risk of spread of fire downwards cannot be assessed with this test. Tests in accordance with this part of the EN 1366 series do not address any risks associated with leakage of dangerous liquids or gases caused by failure of the device in case of fire.
