A fire sequence in the ISO – Room Corner Test and EN – SBI can for example be predicted using the ISO method. The cone calorimeter test is. The ISO Central Secretariat accepts no liability in this area. .. International Standard ISO was prepared by Technical Committee.

It is also possible to measure production of other gas components, like HCN cyanic acid. The surface of the specimens shall be essentially flat. The unit m2 is related to specimen area.
The following test results are tabulated: The emitted gases are collected in a hood and transported away through a ventilation system. Ave 3 min rate of heat release. The Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire.
The specimens shall be representative of the product, and as far as possible be similar to the final ido.
ISO & 2 Cone calorimeter
The data from the test results can be used for modelling bigger fires. Volatile gases from the heated specimen are ignited by an electrical spark igniter.
The test method is used for fire technical modelling. Areas of use The test method is used for fire technical modelling.
Fire gas and smoke yields per gram of sample burnt are also calculated. Time to Peak Rate of Heat Release. Additionaly, measurements of smoke production and production of toxic gases can be performed during the test. Effective heat of combustion. The specimen is mounted on a load cell which records the mass loss rate of the specimen during combustion. Levels of toxic gases can also be measured with FTIR analysis.
Often shortly after ignition for non-FR materials but some may 5606-1 two peaks. The following results are given graphically for each of the applied irradiation levels:. The test gives a possibility to evaluate:.
Combustion gases are collected by an exhaust hood for further analysis. Controlled Atmosphere version available. Smoke production is assessed by measuring attenuation of a laser beam by smoke in the exhaust duct. Peak Rate of Heat Release.
ISO 5660-1 & 2 Cone calorimeter
Maximum thickness 50 mm. Typical output summaries may include: The heat release is measured using the data on measured oxygen concentration in the emitted smoke. This gas analysis makes it possible to calculate heat release rate and to assess production of toxic gases from the specimen.
A complete test requires that at least 12 specimens are available. A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics. Range of Operating Conditions. According to ISO The test report contains information about dimensions, pretreatment and conditioning of the test specimens, and information about the test conditions. The raw data is manipulated and heat release rates and effective heats of combustion are calculated together with averaged data calculated izo oxygen consumption calorimetry.
Up to s. Test procedure When 5606-1 a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level. The test gives a possibility to evaluate: The following test results are tabulated:. The smoke production is measured continually throughout the test 5660- a laser system. A thorough analysis requires testing at several irradiance levels. When testing a product according to Iosa sample with the dimension mm x mm is subjected to a specific irradiance level.
The method follows the procedure given in international standard ISO Dimensions of the specimens: The cone calorimeter test is also largely used when testing products that are under development.
The surface of the sample is heated and starts to emit pyrolysis gases that ignite by a spark igniter. The test method is also used for third party verification production control.
