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 gives a possibility to evaluate: This gas analysis makes it possible to calculate heat release rate and to assess production of toxic gases from the specimen. 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 method follows the procedure given in international standard ISO The 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.
Controlled Atmosphere version available. Time to Peak Rate of Heat Release. When testing a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level.
Areas of use The test method is used for fire technical modelling. It is also possible to measure production of other gas components, like HCN cyanic acid. Smoke production is assessed by measuring attenuation of a laser beam by smoke in the exhaust duct. The test method is also used for third party verification production control. 56660-1 Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire. The following test results are tabulated: A complete test requires that at least 12 specimens are available.
The test method is used for fire technical modelling.
ISO & 2 Cone calorimeter
A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics. Peak Rate of Heat Release. Fire gas and smoke yields per gram of sample burnt are also calculated.
Effective heat of combustion. Additionaly, measurements of smoke production and is of toxic gases can be performed during the test.
The heat release is measured using the data on measured oxygen concentration in the emitted smoke. Ave 5660- min rate of heat release.
Typical output summaries may include: Up to s.
Combustion gases are collected by an exhaust hood for further analysis. Dimensions of the specimens: A thorough analysis requires testing at several irradiance levels.
The smoke production is measured continually throughout the test with a laser system.
ISO – Flame Retardants
The surface of the sample is heated and starts to emit pyrolysis gases that ignite by a spark igniter. The test gives a possibility to evaluate:.
The unit m2 is related to specimen area. Test procedure When iiso a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level.
The specimens shall be representative of the product, and as far as possible be similar to the final product. Range of Operating Conditions. The test report contains information about dimensions, pretreatment and conditioning of the test specimens, and information about the test conditions. Maximum thickness 50 mm. Often shortly after ignition for non-FR materials but some may show two peaks.
The following test results are tabulated:.
ISO 5660-1 & 2 Cone calorimeter
The following results are given graphically for each of the applied irradiation levels:. Levels of toxic gases can also be measured with FTIR analysis. According to ISO Lso 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.
