    A study of fire performance of textile membranes used as building components2012In: Fire and Materials, ISSN 0308-0501, E-ISSN 1099-1018, Vol. 36, no 8, p. 648-660Article in journal (Refereed)
    Abstract [en]

    The advantages of textile materials as building components include low weight, and in the case of textile membranes, the advantages include translucency and architectural possibilities. A common disadvantage, however, is the fire property of textile materials, which highlights the importance of fire safety assessments for building application of such materials. The work presented in this paper was conducted within the European project contex-T, 'Textile Architecture - Textile Structures and Buildings of the Future'. This paper presents the results of reaction-to-fire tests required for European Standard (EN) 13501-1 classification conducted with a number of textile membranes. The classification results are compared for a selection of these membranes with the information gained from a large-scale reference test that was designed within the project. The reference test was based on the International Organization for Standardization (ISO) 9705 room test. It was seen that the reference test could separate the performance of the different types of membranes investigated and the repeatability of duplicate tests performed was acceptable. However, the classification of the materials by test results from the Single Burning Item (SBI) test (EN 13823) and the small flame test (EN ISO 11925-2) did not reflect the performance of the membranes in the large-scale test properly in all aspects important for fire safety. Most significantly, the 'burn-through' and the associated opening of a hole in the polyvinyl chloride/polyester membranes tested ventilated the hot smoke gases out of the reference room that resulted in limited flame spread and heat production. This mechanism is not modelled correctly by the SBI test, which leads to a discrepancy between classification and large-scale behaviour.

    Detailed study of distribution patterns of polycyclic aromatic hydrocarbons and isocyanates under different fire conditions2014In: Fire and Materials, ISSN 0308-0501, E-ISSN 1099-1018, Vol. 38, no 1, p. 125-144Article in journal (Refereed)
    Abstract [en]

    This study has examined the distribution patterns between gas phase and particle phase of some chemical compounds produced in fires. It has also addressed the question of the distribution of individual particle-associated species between the different size-ranges of particles. The chemical compounds studied and discussed in this paper are polycyclic aromatic hydrocarbons (PAHs), and isocyanates. The steady-state tube furnace, ISO/TS 19700, was chosen as the physical fire model in order to study the production of particles from different types of fire exposure, that is, oxidative pyrolysis, well-ventilated flaming fires and under-ventilated flaming post-flashover fires. Two materials were chosen for investigation, a polyvinyl chloride (PVC) carpet and a wood board. The particle production from the two materials investigated varied concerning both the amounts produced and the particle size distributions. The analysis of PAHs showed that volatile PAHs were generally dominant. However, when the toxicity of the individual species was taken into account, the relative importance between volatile and particle-associated PAHs shifted the dominance to particle-bound PAH for both materials. The substantial degradation in the tests of the low polyurethane content of the PVC carpet, and the (4,4′-methylenediphenyl diisocyanate)-based binder in the wood board resulted in no or very small amount of quantifiable diisocyanates.

    Modelling the structural response of fibre-reinforced composites subjected to fire2014Conference paper (Refereed)
    Abstract [en]

    The present contribution details the development and implementation of dedicated material models for the finite element computation of the thermal and mechanical response of polymer compositestructures subjected to fire. The material models are developed so that mechanical and thermal properties at the ply level can be calculated from the constituent's properties, therefore allowing for a greater flexibility in architecture and reduced testing programs. The degradation of the resin during fire is predicted during the thermal analysis. Its effect, together with the effect of temperature, on the mechanical response is accounted for in the material model. The models are validated against a mini furnace experiment.

    Emissions from Fires Part II: Simulated Room Fires2004In: Fire Technology, Vol. 40, no 1, p. 59-74Article in journal (Refereed)
    Abstract [en]

    Detailed quantitative characterization of the combustion gases from a series of room fires is reported in this article. Three simulated room fires were conducted with a test room containing a typical domestic fuel load of furniture including a TV-set. Two types of TV-sets were studied in the experiments, i.e. those containing fire retarded and non-fire retarded enclosure material. The measurement of the combustion gases included inorganic species and various organic species among them polychlorinated and polybrominated dibenzodioxins and furans, and selected brominated flame retardant agents. The detailed quantitative characterization of the combustion gases from the room fires forms a unique source of emission data for fire incidents in buildings. Chlorinated dibenzodioxins and furans were found in the combustion gases from all room tests. No brominated dioxins were found, however brominated furans were found. Further, the results from the room tests indicate that a TV-set treated with brominated flame retardants included in the fire load of a room fire does not necessarily increase the emission of bromine containing organic combustion products. The methodology applied for the sampling and analysis has been described in Part I of this series of articles.

    An experimental evaluation of the equivalence ratios in tests apparatus used for fire effluent toxicity studies2021In: Fire and Materials, ISSN 0308-0501, E-ISSN 1099-1018, Vol. 45, no 8, p. 1085-1095Article in journal (Refereed)
    Abstract [en]

    An experimental evaluation was conducted on the bench-scale test methods most commonly applied for generating data for fire toxicity assessments. The test methods evaluated were ISO/TS 19700, ISO 5660-1 with the controlled atmosphere box, and ISO 5659-2. Toxic gases were quantitatively analyzed using Fourier transfer infrared spectroscopy. Tests were made with 11 different insulation materials and polymethylmethacrylate as a reference material. The evaluation made was on the combustion conditions in the test apparatus, not generally on the precise yields measured. The evaluation focused on the ventilation conditions created in flaming combustion tests. It was seen that ISO/TS 19700 currently offers the best means among the three test methods evaluated for conducting tests at pre-determined and controlled equivalence ratios. The controlled-atmosphere cone calorimeter does not give a prolonged steady flaming combustion period for most materials and the influence of vitiation was difficult to predict and limiting in achieving higher equivalence ratios, with the test settings applied. ISO 5659-2 generally accumulates a mixture of gases from periods of both flaming and nonflaming combustion in a test, and the yields measured do not, in those cases, represent any specific combustion stage. For materials not showing flaming combustion, for example, mineral fiber products, the influence on the test conditions regarding oxygen consumption and heat generation from the material itself is limited compared to burning materials. However, there were specific properties and limitations of the different test methods observed that are important to consider.

    Experimental evaluation of fire toxicity test methods2018Report (Other academic)
    Abstract [en]

    An experimental evaluation of the most common bench-scale tests methods for fire toxicity was conducted by RISE Fire Research. The background of the work was the on-going discussion in the fire community on the applicability and relevance of these test methods.

    The test methods included in the programme were the ISO/TS 19700 steady-state tube furnace (SSTF), the controlled atmosphere cone calorimeter (CACC), and the EN 45545-2 smoke chamber test (SC). In these tests the production of selected toxic gases was quantitatively analysed using FTIR. Tests for the measurement of toxic gas production were made with eleven different materials used as test specimens, both combustible and non-combustible materials. The materials were commercially available insulation products provided by EURIMA, the sponsor of the project. These materials should not be regarded as typical or fully representative of a product category.

    The evaluation of the results from the different test methods was divided into combustible test specimens and non-combustible test specimens. That was because the test conditions in the first case are greatly influenced by the combustion behaviour of the test specimen, while in the second case the test conditions are more constant.

    A general observation was that there in many cases was correlation between both species composition and level of toxic gas species yields between test methods when the combustion conditions were similar. In cases where yields differed significantly it could in most cases be explained by clear differences in test conditions.

    For combustible materials it was concluded that the SSTF offers the best means for conducting tests at pre-decided and controlled flaming combustion conditions. The CACC does not give steady-state flaming combustion and the influence of vitiation was limited in the tests made. The SC generally accumulates a mixture of gases from both flaming and non-flaming combustion periods in a test, and the yields measured do not in those cases represent any specific combustion stage.

    For non-combustible materials a general observation was that any of the test methods investigated in principle could be used since the influence on the test conditions from the material itself is limited compared to combustible materials. However, there were specific properties and limitations of the different test methods observed that are important to consider.

    Effect of gas cell pressure in FTIR analysis of fire effluents2014In: Fire and Materials, Vol. 39, no 7, p. 675-84Article in journal (Refereed)
    Abstract [en]

    The analysis of fire effluents using Fourier Transform Infrared Spectroscopy (FTIR) is increasing in the field of fire science. This technique is very powerful and may be very selective and precise if the FTIR instrument is properly calibrated. However, results are sensitive to instrumental parameters, including especially pressure effects on the contents in the measurement cell. This communication presents experimental and numerical evaluation of pressure effects in FTIR analysis, and an evaluation of the feasibility and limitation of pressure corrections. The work performed concerns experimental measurements on pressure influence with four different gases, at different levels of concentration, and for one of the gases with different equipment from two laboratories. Some of these results are compared with theoretical models obtained from HITRAN database. Finally, this communication proposes limitations to the range of validity of correction if the actual pressure and the pressure for calibration differ, and suggests a tolerance of ±10 Torr on pressure variation for application of the method.

    How Phosphorous Flame Retardant Additives Affect Benzoxazine-Based Monomer and Polymer Properties2023In: Macromolecular materials and engineering, ISSN 1438-7492, E-ISSN 1439-2054Article in journal (Refereed)
    Abstract [en]

    The phosphorous-based flame retardant additives poly(m-phenylene methylphosphonate) (PMP) and resorcinol bis(diphenyl phosphate) (RDP) are reacted with bisphenol F and aniline–based benzoxazine (BF-a). DSC, rheological analysis, FT-IR, and soxhlet extraction reveal the covalent incorporation of both FR additives—initiating phenols in PMP structure as well as free phenols generated via transesterification reaction in the case of RDP. In contrast to PMP, RDP elongates the processing window but decreases the thermo–mechanical properties. Both additives increase the resistance in reactions against small flames with solely a phosphorous loading of 0.3 wt%, resulting in a V-0 rating and an improvement in the OI value by up to 2% for RDP and 4% for PMP. Both FRs reduce the heat release rate but increase the smoke production and the smoke toxicity in the case of RDP. © 2023 The Authors.
