38、ive a fully vandalized seat, if the inner layer is bonded to the interior construction (i.e. foam), then it could be impossible to lift the cut layer without application of force to pull it away (see A.6).3.9.2partial vandalizationcutting of some of the outer layers of the seat covering onlyNOTE Par
39、tial vandalization can be achieved for example if anti-vandal materials are used beneath the outer covering.4 Assessment method for the fire behaviour of rail seats4.1 General requirements for assessmentThe test seats are subjected to a specified flaming ignition source. The reactions are measured a
40、nd analysed.The flaming ignition source is a representation of the thermal attack of the ignition model 1 of EN 45545-1 and shall be represented by the application of a gas burner for three minutes, supplying 15 kW of heat (see 5.3 for details of the burner and 7.2 for the test procedure).The test p
41、rogramme shall be undertaken, using the quantities of seats specified in 4.2.2 to obtain representative results for the type of seat to be assessed. Heat release rate (HRR), maximum average heat release (MARHE), total smoke production (TSP) and flame height shall be evaluated.Test equipment specific
42、ations are set out in Clause 5.8 BS EN 16989:2018EN 16989:2018 (E)The preparation of the seat specimens is set out in Clause 6 taking into account vandalization.The fire test procedure for each seat and the requirements for analysis and reporting of the results are set out in Clause 7.A standardized
43、 procedure to assess a seats potential for vandalization is set out in Annex A.Calibration procedures are set out in Annex B.This test protocol does not provide information on the fire performance of seats under conditions other than those specified in this standard.4.2 Seat test programme4.2.1 Test
44、 programme requirementsThe seats shall be representative of production for the type of seat being assessed. The seats shall be complete and include back and base shells and all upholstery as used in practice, and if applicable arm rests and head rests. The testing programme is summarized in the flow
45、 chart set out in Figure 2.Items which are removable by hand (e.g. anti-macassars, pillows) which are assessed separately according to EN 45545-2 shall not be included in the test specimens.Vandalization requirements for the test seats shall be determined according to 4.2.2.All seats to be tested sh
46、all be conditioned according to Clause 6 and tested according to Clause 7. If vandalization is required, it shall be applied according to 6.2.The test programme shall be in accordance with 4.2.3.For each individual fire test the results shall be reported according to the requirements of 7.2.7.In add
47、ition a summary of results for the seat type assessed shall be produced to tabulate for all the seats tested the results required for product classification: MARHE, Peak HRR, TSP and flame height.9BS EN 16989:2018EN 16989:2018 (E)Figure 2 Seat test flow chart4.2.2 Seat vandalizationWhere a seats pot
48、ential for vandalization is known, it is not required to make a new assessment provided that the results of earlier tests according to Annex A of this document are available and are included in the seat test reports.10 BS EN 16989:2018EN 16989:2018 (E)For upholstered seats, as shown in Figure 2, the
49、 seat is either:1) tested in a fully vandalized condition, or2) considered to be unvandalizable or partially vandalizable by incorporating particular materials and construction techniques which have been already assessed using the procedure set out in Annex A, or3) assessed using the procedure set out in Annex A to determine if the seat is tested fully vandalized, partially vandalized or unvandalized.NOTE A seat with a replaceable outer covering which can be cut and layers beneath which cannot be cut when tested accordin
