Peak Rate of Heat Release.

The test gives a possibility to evaluate:. Additionaly, measurements of smoke production and production of toxic gases can be performed during the test. Combustion gases are collected by an exhaust hood for further analysis.

ISO 5660-1 & 2 Cone calorimeter

Time to Peak Rate of Heat Release. Test procedure When testing a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level.

Range of Operating Conditions. Controlled Atmosphere version available. 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.

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. The following test results are tabulated:. The Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire. A complete test requires that at least 12 specimens are available. The test method is used for fire technical modelling. The heat release is measured sio the data on measured oxygen concentration in the emitted smoke.

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.

The test method is also used for third party verification production control. The data from the test results can be used for modelling bigger fires. Ave 3 min rate of heat release.

A whole range of different data can be compared in order to eliminate products that will not have the 56601 fire characteristics. The surface of the specimens shall be essentially flat. The method follows the procedure given in international standard ISO The emitted gases are collected in a hood and transported away through a ventilation system. The test report contains information about dimensions, pretreatment and conditioning of the test specimens, and information about the test conditions.

Maximum thickness 50 mm. Effective heat of combustion. Levels of toxic gases can also be measured with FTIR analysis. A thorough analysis requires testing at several irradiance levels.

Typical output summaries may include: Fire gas and smoke yields per gram of sample burnt are also calculated. The test gives a possibility to evaluate: The cone calorimeter test is also largely used when testing products that are under development.

Volatile gases from the heated specimen are ignited by an electrical spark igniter. The specimen is mounted on a load cell isk records the mass loss rate of the specimen during combustion.

Often shortly after ignition for non-FR uso but some may show two peaks. The surface of the sample is heated and starts to emit pyrolysis gases that ignite by a spark igniter. Up to s.
