The test report contains information about dimensions, pretreatment and conditioning of the test specimens, and information about the test conditions. The raw data iiso manipulated and heat release rates and effective heats 5660-1 combustion are calculated together with averaged data calculated by oxygen consumption calorimetry.
A thorough analysis requires testing at several irradiance levels. Typical output summaries may include: This gas analysis makes it possible to calculate heat release rate and to assess production of toxic gases from the specimen. The test gives a possibility to evaluate: Peak Rate of Heat Release. Dimensions of the specimens: The following test results are tabulated:.
Up to s. Combustion gases are collected by an exhaust hood for further analysis.
ISO & 2 Cone calorimeter
Test procedure When testing a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level. The following test results are tabulated: The surface of the specimens shall be essentially flat.
Controlled Atmosphere version available. Smoke production is assessed by measuring attenuation of a laser beam by smoke in the exhaust duct. The 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.
ISO 5660-1 & 2 Cone calorimeter
The following results are given graphically for each of the applied irradiation levels:. The cone calorimeter test is also largely used when testing products that are under development.
Effective heat of combustion. The Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire. The method follows the procedure given in international standard ISO The specimen is mounted isso a load cell which records the mass loss rate of the specimen during combustion. Time to Peak Rate of Heat Release. The specimens shall be representative of the product, and as far as possible be similar to the final product.
The unit m2 is related to specimen area.
Maximum thickness 50 mm. The emitted gases are collected in a hood and transported away through a ventilation system. Ave 3 min rate of heat release. The heat release is measured using the data on measured oxygen 55660-1 in the emitted smoke. When testing a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level.
The test gives a possibility to evaluate:. Levels of toxic gases can also be measured with FTIR analysis.
A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics. According to ISO The test method is used for fire technical modelling.
Fire gas and smoke yields per gram of sample burnt are also calculated.
Additionaly, measurements of smoke production and production of toxic gases can be performed during isp test. Often shortly after ignition for non-FR materials but some may show two peaks. The test method is also used for third party verification production control. A complete test requires that at least 12 specimens are available.
The smoke production is measured continually throughout the test with a laser system. Range of Operating Conditions. The surface of the sample is heated and starts to emit pyrolysis gases that ignite by a kso igniter.
It is also possible to measure production of other gas components, like HCN cyanic acid. Areas of use The test method is used for fire technical modelling.
