摘要:

AbstractLong‐lived end‐chain peroxy radicals have been detected during the thermo‐oxidative degradation of PTFE. These radicals are associated with the fine particulate, which is the established cause of the ultra‐high toxic potency of PTFE produced under the conditions employed. The particulate has been further characterized by a vareity of thermo‐analytical methods. Fluid‐flow modelling analysis has been used to simulate the recirculatory behaviour, characteristic of the NIST cup furnace toxicity test, which may effect the continuous regeneration of t

摘要:

AbstractA laboratory study of the ignition of building details incorporating timber, under bushfire conditions, using ‘mock‐ups’ of these details and both realistic (leaves and twigs) and, mainly, artificial (cribs) ignition sources has been carried out. Parameters such as mock‐up type, moisture content of the timber comprising the mock‐ups, and temperature and relative humidity of the experimental atmosphere were examined. It was found that all these parameters affected the ignition and flame propagation induced and that under conditions typical of a severe bushfire, only very small amounts of fuel were required to cause ignition. These results support the belief, based on field studies, that ignition of exterior building details composed of timber plays an important role in the destruction of buildings in

摘要:

AbstractAn evaluation of the cone calorimeter by the Association of Plastic Manufacturers in Europe (APME) involved testing of 25 plastic materials together with two natural polymers. Specimen preparation is identified as having an important influence on the results, especially for certain types of material. Ignition time, rate of heat release (RHR) and smoke results are presented to show the influence of external heat flux. The dynamic smoke results (which should be measured from the time of exposure) are only relevant to well‐ventilated fires unless the cone calorimeter is specially modified. For a complete evaluation a cumulative smoke measurement may be needed in addition. Although the cone calorimeter is a valuable research tool, and may be used frequently in industry, it needs to be made more robust and user friendly to avoid excessive downtime and to reduce calibration time. If the instrument is to be used for routine development and quality assurance, only one or two heat flux levels should be selected. These could represent a developing and a developed fire and should depend on the product applicatio

摘要:

AbstractEffective exchange of fire test data, even within a single laboratory, has been difficult due to the multiple, and often incompatible, data formats and hardware. This issue has been addressed by a careful study of user needs, leading to the development of a series of standard formats whereby fire test data could easily be exchanged among users. These formats have been made practical by the development of a computer program—the Fire Data Management System (FDMS)—and pertinent hardware standards. The system includes the most commonly used of modern‐day fire test methods, but also has provisions for future extension to other tests of int

摘要:

AbstractCombustible dusts, based on tests conducted in the Setchkin Furnace on five representative dusts, are shown to have two distinct layer minimum ignition temperatures, designated MITnon‐flamingand MITflaming. The MITnon‐flamingis the one usually reported in the literature; the MITflamingis determined by starting at a much higher temperature and working downwards. MITflamingcan yield a different ranking of dust flammability than MITnon‐flaming. The MITflamingappears to be more closely correlated to the MIT of dust clouds and to the test prescribed for flammable solids in the US Code of Federal Regulations than the MITnon‐

AbstractA general correlation has been obtained for prediction of closed‐cup flash points of organic compounds from their normal boiling points and specific gravity. Predicted flash points are within an average deviation of 8.301 of the reported value
