It is also possible to measure production of other gas components, like HCN cyanic acid. The test method is also used for third party verification production control.
ISO 5660-1 & 2 Cone calorimeter
Dimensions of the specimens: Additionaly, measurements of smoke production and production of toxic gases can be performed during the test. Smoke production is assessed by measuring attenuation of a laser beam by smoke in the exhaust duct.
The specimens shall be representative of the product, and as far as 56601- be similar to the final product. A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics. 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. A thorough analysis requires testing at several irradiance levels.
Effective heat of combustion.
The unit m2 is related to specimen area. Volatile gases from the heated specimen are ignited by an electrical spark igniter. Ave 3 min rate of heat release. According to ISO The emitted gases are collected in a hood and transported away through a ventilation system. Maximum thickness 50 mm. Controlled Atmosphere version available. When testing a product according to ISOa sample with the dimension mm x mm is 56601 to a 6560-1 irradiance level.
ISO – Flame Retardants
Up to s. Time to Peak Rate of Heat Release. Levels of toxic gases can also be measured with FTIR analysis. Fire gas and smoke yields per gram of sample burnt are also calculated. The following test results are tabulated:.
ISO & 2 Cone calorimeter
Range of Operating Conditions. The smoke production is measured continually throughout the test with a laser system. The cone calorimeter test is also largely used when testing products that are under development. The Cone Calorimeter test is at present the most advanced method for assessing materials reaction to fire. Test procedure When testing a product according to ISOa sample with the dimension mm x mm is subjected to a specific irradiance level.
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. Areas of use The test method is used for fire technical modelling.
Peak Rate of Heat Release. 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 test report 56601 information about dimensions, pretreatment and conditioning of the test specimens, and information about the test conditions. The test gives a possibility to evaluate: Isi method follows the procedure given in international standard ISO Typical output summaries may include: Combustion gases are collected by an exhaust hood for further analysis. The test gives a possibility to evaluate:.
