Up to s.
The smoke production is measured continually throughout the test with a laser system. The following test results are tabulated: The test report contains information about dimensions, pretreatment and conditioning of the test specimens, and information about the test conditions. The data from uso test results can be used for modelling bigger fires.
The test gives a possibility to evaluate:. Effective heat of combustion. The test method is also used for third party verification production control. Controlled Atmosphere version available. The heat release 566-01 measured using the data on measured oxygen concentration in the emitted smoke. The Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire.
Smoke production is assessed by measuring attenuation of a laser beam by smoke in the exhaust duct.
ISO & 2 Cone calorimeter
The test gives a possibility to evaluate: The following test results are tabulated:. It is also possible to measure production of other gas components, like HCN cyanic acid. Dimensions of the specimens: Peak Rate of Heat Release. The cone calorimeter test is also largely used when testing products that are under development.
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. Often shortly after ignition for non-FR materials but some may show two peaks. Fire gas and smoke yields per gram of sample burnt are also calculated.
The following results are given graphically for each of the applied irradiation levels:.
Range of Operating Conditions. Typical output summaries may include: A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics. The specimens shall be representative of the product, and as far as possible be similar to the final product.
Volatile gases from the heated specimen are ignited by an electrical spark igniter.
The surface of the sample is heated and starts to emit pyrolysis gases that ignite by a spark igniter. The test method is used for fire technical modelling. A complete test isk that at least 12 specimens are available.
ISO 5660-1 & 2 Cone calorimeter
Time to Peak Rate of Heat Release. Levels of 55660-1 gases can also be measured with FTIR analysis. Areas of use The test method is used for fire technical modelling.
Maximum thickness 50 mm. Test procedure When testing a product 5660- to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level.
According to ISO Additionaly, measurements of smoke production and production of toxic gases can be performed during the test. The emitted gases are collected in a hood and transported away through a ventilation system. The specimen is mounted on a load cell which records the mass loss rate of the specimen during combustion. Combustion gases are collected by an exhaust hood for further analysis.
