In an ISO 5660 Cone Calorimeter, heat fluxes were applied to a polyvinyl chloride–based floor covering to characterize their influence on the thermal decomposition parameters as well as on the concentrations of species emitted during the combustion process. Gas concentrations were quantified for identifying the fire behaviour and the decomposition chemistry. Thus, carbon monoxide, carbon dioxide, water, hydrogen chloride and oxygen with concentrations and emission yields of high consistency were encountered at all heat fluxes considered. Moreover, nitrogen monoxide, sulphur dioxide, hydrogen cyanide and lightweight hydrocarbons were observed with low concentrations and emission yields. Other species can be considered as negligible due to their concentrations close to zero at all heat fluxes studied. Furthermore, using the oxygen consumption method, heat release rate, total heat release and effective heat of combustion were also calculated for each irradiance level and were compared with data found in the literature.

在锥形量热仪中表征聚氯乙烯地板覆盖物的热分解参数

在 ISO 5660 锥形量热仪中，将热通量应用于基于聚氯乙烯的地板覆盖物，以表征它们对热分解参数以及燃烧过程中排放物质浓度的影响。气体浓度被量化以识别火灾行为和分解化学。因此，一氧化碳、二氧化碳、水、氯化氢和氧气的浓度和排放量都具有高一致性，在所有考虑的热通量下都会遇到。此外，还观察到一氧化氮、二氧化硫、氰化氢和轻质碳氢化合物的浓度和排放量都很低。其他物种可以被认为是可以忽略不计的，因为它们在所有研究的热通量下的浓度都接近于零。此外，使用耗氧量法，
