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.

The test report contains information about dimensions, pretreatment 566-1 conditioning of the test specimens, and information about the test conditions. The Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire.
ISO & 2 Cone calorimeter
The unit m2 is related to specimen area. The surface of 5660- sample is heated and starts to emit pyrolysis gases that ignite by a spark igniter. Range of Operating Conditions. Time to Peak Rate of Heat Release. The cone calorimeter test is ido largely used when testing products that are under development. The data from the test results can be used for modelling bigger fires.
According to ISO 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.
ISO 5660-1 & 2 Cone calorimeter
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 56600-1. The test gives a possibility to evaluate: Often shortly after ignition for non-FR materials 5660-1 some may show two peaks.
Dimensions of the specimens: Areas of use The test method is used for fire technical modelling. A complete test requires that at least 12 specimens are available.
Up to s. Ave 3 min rate of heat release. The test method is also used for third party verification production control. Controlled Atmosphere version available. The following results are given graphically for each of the applied irradiation levels:.
Combustion gases are collected by an exhaust hood for further analysis. Volatile gases from the heated specimen are ignited by an electrical spark igniter. The following test results are tabulated:. The test gives a possibility to evaluate:.
A thorough analysis requires testing at several irradiance levels. The heat release is measured using the data on measured oxygen concentration in the emitted smoke. A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics. When testing a product according 5660-1 ISOa sample with the dimension mm x mm is subjected to a specific irradiance level.
The specimen is mounted on a load cell which records the mass loss rate of the specimen during combustion.
Additionaly, measurements of smoke production and production of toxic gases can be performed during the test. The test method is used for fire technical modelling. Levels of toxic gases can also be measured with FTIR analysis. The specimens shall be representative of the product, and as far as possible be similar to the final izo.
The emitted gases are collected in a hood and transported away through a ventilation system. Peak Rate of Heat Release.
Maximum thickness 50 mm. Test procedure When testing a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level. This gas analysis 5660–1 it possible to calculate heat release rate and to assess production of toxic gases from the specimen. Effective heat of combustion.
The method follows the procedure given in international standard ISO The smoke production is measured continually throughout the test with a laser system.
Smoke production is assessed by measuring attenuation of a laser beam by smoke in the exhaust duct.
The surface of the specimens shall be essentially flat. Typical output summaries may include: The following test results are tabulated:
