This European Standard specifies requirements and test methods for flue gas silencers made of metal that are used as accessories in order to reduce the noise level of combustions appliances.The standard covers silencers in the connecting flue pipes and on top of chimneys.This standard does not cover silencers installed as chimney sections. This standard excludes active silencers.

This Europen Standard specifies test methods for the determination of the fundamental frequency, damping, unit point load deflection and acceleration of timber or wood based composite beams and flooring systems.

This European Standard provides the reaction to fire classification procedure for electric cables.NOTE For the purpose of this European Standard the term "electric cables" covers all power, control and communication cables, including optical fibre cables.

This document specifies test methods for determining the contribution of fire protection kits to the fire resistance of structural timber members.Such fire protection kits include claddings, sprayed fire protection and reactive coatings.The method is applicable to all fire protection kits used for the protection of timber members. These can be fixed directly, totally or in part, to the timber member and can include an air gap between the fire protectionkit and the timber member, as an integral part of its design.Evaluation of timber constructions protected by horizontal or vertical protective membranes are the subject of EN 13381-1 or EN 13381-2 respectively.The test method is applicable to the determination of the contribution of fire protection kits to the fire resistance of loadbearing timber structural members including floors, roofs, walls, beams and columns.This document contains the fire test which specifies the test to be carried out to determine the ability of the fire protection kit at a specified thickness to delay the temperature rise throughout the timber member, to determine the ability of the fire protection kit at a specified thickness to remain coherent and fixed to the timber member and to provide data for determining the charring rate of the protected test member, when exposed to the standard temperature/time curve according to the procedures defined herein. This document is not appropriated to classify the tested assembly according to EN 13501-2.The test to subject reactive protection material to a smouldering temperature time fire curve and the special circumstances for this are detailed in Annex G.The fire test methodology makes provision for the collection and presentation of data which can be used as direct input to the calculation of fire resistance of timber members in accordance with the procedures given in EN 1995-1-2.A description of the relationship of this test method and the assessment of the results obtained therefrom to EN 1995-1-2 and guidelines for the use of this test method in accordance with that standard are given in Annex B.This document also contains the assessment which indicates how the analysis of the test data should be 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 with the direct application of the results to different timber constructions with the specified thickness and fixation of the applied fire protection kit tested.

This European Standard specifies requirements of curtain walling kit intended to be used as a building envelope to provide weather resistance, safety in use and energy economy and heat retention and provides test/assessments/calculation methods and compliance criteria of the related performances.The curtain walling kit covered by this standard should fulfil its own integrity and mechanical stability but does not contribute to the load bearing or stability of the main building structure, and could be replaced independently of it.This standard applies to curtain walling kit ranging from a vertical position to ± 15° from the vertical. Any sloping parts should be contained within the curtain walling kit.This standard is applicable to the whole of the curtain walling kits, including the fixings.Curtain walling according to this standard is intended to be used as part of the building envelope.This European Standard does not include:- Patent glazing (glazed sloping roofs) kits;- Roof glazing constructions;- Façades made of precast concrete panels as part of the wall (see EN 14992).NOTE 1 Precast concrete panels may be used in curtain walling kits as infill panels.NOTE 2 Durability of structural sealed glazing infills is not covered by this standard.
