A complete test requires that at least 12 specimens are available. The following results are given graphically for each of the applied irradiation levels:.

ISO & 2 Cone calorimeter

This gas analysis makes it possible to calculate heat release rate and to assess production of toxic gases from the specimen. Combustion gases are collected by an exhaust hood for further analysis. The cone calorimeter test is also largely used when testing products that are under development. Areas of use The test method is used for fire technical modelling. The emitted gases are collected in a hood and transported away through a ventilation system.

The test method is also used for third party verification isi control. Time to Peak Rate of Heat Release. A thorough analysis requires testing at isso irradiance levels. Often shortly after ignition for non-FR materials but some may show two peaks. The following test results are tabulated:. 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.


A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics. Typical output summaries may include: The test report contains information about dimensions, pretreatment and conditioning of the test specimens, and information about the test conditions.

The test gives a possibility to evaluate: Dimensions of the specimens: 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 surface of the sample is heated and starts to emit pyrolysis gases that ignite by a spark igniter. The specimen is mounted on a load cell which records the mass loss rate of the specimen during combustion. Maximum thickness 50 mm.

ISO – Flame Retardants

The test method is used for fire technical modelling. 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.

Effective heat of combustion. The unit m2 isoo related to specimen area. Ave 3 min rate of heat release. The test gives a possibility to evaluate:. The specimens shall be representative of the product, and as far as possible be similar to the final product.


Test procedure When testing a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level. The heat release is measured using the data on measured oxygen concentration in the emitted smoke.

Peak Rate of Heat Release. Additionaly, measurements of smoke production and production of toxic gases can be performed during the test. Controlled Atmosphere version available. The following test results are tabulated: When testing a product according to ISO ido, a sample with the dimension mm x mm is subjected to a specific irradiance level.

The surface of the specimens shall be essentially flat.

Levels of toxic gases can also be measured with FTIR analysis. Up to s.

ISO 5660-1 & 2 Cone calorimeter

The method follows the procedure given in international standard ISO The Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire. Range of Operating Conditions. According to ISO The smoke production is measured continually throughout the test io a laser system. Volatile gases from the heated specimen are ignited by an electrical spark igniter.
