This gas analysis makes it possible to calculate heat release rate and to assess production of toxic gases from the specimen. It is also possible to measure production of other gas components, like HCN cyanic acid.

The following results are given graphically for each of the applied irradiation levels:. Typical output summaries may include: Often shortly after ignition for non-FR materials but some may show two peaks.

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 data ido the test results can be used for modelling bigger fires.

Additionaly, measurements of smoke production and production of toxic gases can be performed during the test. The cone calorimeter test is also largely used when testing products that are under development. Range of Operating Conditions. Peak Rate of Heat Release.

A complete test requires that at least 12 specimens are available. The surface of the 566-1 is heated and 566-01 to emit pyrolysis gases that ignite by a spark igniter.

The smoke production is measured continually throughout the test with a laser system. Maximum thickness 50 mm.

Levels of toxic gases can also be measured with FTIR analysis. Smoke production is assessed by measuring attenuation of a laser beam by smoke in the exhaust duct. The test method is used for fire technical modelling.

The test gives a possibility to evaluate:. According to ISO The Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire.

The following test results are tabulated: Fire gas and 55660-1 yields per gram of sample burnt are also calculated. The heat release is measured using the data on measured oxygen concentration in the emitted smoke. Areas of use The test method is used for fire technical modelling.

A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics.

Volatile gases from the heated specimen are ignited by an electrical spark igniter. The emitted gases are collected in a hood and transported away through a ventilation system.

The surface of the specimens shall be essentially flat. Time to Peak Rate of Heat Release.

ISO – Flame Retardants

The test method is also used for third party verification production control. Test procedure When testing a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level.

The method follows the procedure given in international standard ISO Effective heat of ido. Up to s. The following test results are tabulated:. A thorough analysis requires testing at several irradiance levels. Controlled Atmosphere version available.

ISO 5660-1 & 2 Cone calorimeter

The specimen is mounted on a load cell which records the mass loss rate of the specimen during combustion. The unit m2 is related to specimen area. Combustion gases are collected by an exhaust hood for further analysis.
