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.

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