ISO & 2 Cone calorimeter
Fire gas and smoke yields per gram of sample burnt are also calculated. Volatile gases from the heated specimen are ignited by an electrical spark igniter.
It is also possible to measure production of other gas components, like HCN cyanic acid. The test gives a possibility to evaluate: Areas of use The test method is used for fire technical modelling.
ISO 5660-1 & 2 Cone calorimeter
The test gives a possibility to evaluate:. Ave 3 min rate of heat release. Maximum thickness 50 mm. Additionaly, measurements of smoke production and production of toxic gases can be performed during the test. A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics.
Test procedure When testing a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level. The smoke production is measured continually throughout the test with a laser system. The specimen is mounted on a load cell which records the mass loss rate of the specimen during combustion. The following test results are tabulated: The data from the test results can be used for 5606-1 bigger fires.
Effective heat of combustion. Smoke production is assessed by measuring attenuation of a laser beam by smoke in the exhaust duct.
The cone calorimeter test is also largely used when testing products that are under development. Time to Peak Rate of Heat Release. Controlled Atmosphere version available.
The following test results are tabulated:.
The unit m2 is related to specimen area. Dimensions of the specimens: The following results are given graphically for each of the applied irradiation levels:.
The surface of the sample is heated and starts to emit pyrolysis gases that ignite by a spark igniter. The test ieo is also used for third party verification production control. The specimens shall be representative of the product, and as far as possible be similar to the final product. The test report contains information about dimensions, pretreatment and conditioning of the test specimens, and information about the test conditions.
Typical output summaries may include: Up to s. The heat release is measured using the data on measured oxygen concentration in the emitted smoke. A complete test requires that at least 12 specimens are available.
Levels of toxic gases can also be measured with FTIR analysis. 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.
This gas analysis makes it possible to calculate heat release rate and to assess production of toxic gases from the specimen. The method follows the procedure given in international standard ISO A thorough 566-01 requires testing at ios irradiance levels. When testing a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level.
