The test gives a possibility to evaluate:. A thorough analysis requires testing at several irradiance levels. The test gives a possibility to evaluate: The surface of the sample is heated and starts to emit pyrolysis gases that ignite by a spark igniter. The Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire. Additionaly, measurements of smoke production and production of toxic gases can be performed during the test.

Dimensions of the specimens: Ave 3 min rate of heat release. Controlled Atmosphere version available. Smoke production is assessed by measuring attenuation of a laser beam by io in the exhaust duct.

It is also possible to measure production of other gas components, like HCN cyanic acid. The heat 56600-1 is measured using the data on measured oxygen concentration in the emitted smoke. Levels of toxic gases can also be measured with FTIR analysis. The following test results are tabulated:. When testing a product according to ISOa sample with the dimension mm iao 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.

The following results are given graphically for each of the applied irradiation levels:. A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics. The test method is also used for third party verification production control. Peak Rate of Heat Release.

According to ISO The data from the test results can be used for modelling bigger fires. Fire gas and smoke yields per gram of sample burnt are also calculated.

ISO & 2 Cone calorimeter

The emitted gases are collected in a hood and transported away through a ventilation system. Volatile gases from the heated specimen are ignited by an electrical spark igniter. Time to Peak Rate of Heat Release. Maximum thickness 50 mm.

Typical output summaries may include: The test method is used for fire technical modelling. Up to s. Often shortly after ignition for non-FR materials but some may show two peaks.

Areas of use The test method is used for fire technical modelling. The following test results are tabulated: Test procedure When testing a product according to 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. The method follows the procedure given in international standard ISO The unit m2 is related to specimen area. A complete test requires that at least 12 specimens are available. Effective heat of combustion.

ISO 5660-1 & 2 Cone calorimeter

Range of Operating Conditions. The smoke production is measured continually throughout the test with ios laser system. Combustion gases are collected by an exhaust hood for further analysis.

This gas analysis makes it possible to calculate heat release rate and to assess production of toxic gases from the specimen. The cone calorimeter test 5660-11 also largely used when testing products that are under development. 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 test report contains information about dimensions, pretreatment and conditioning of the test specimens, and information about the test conditions.
