ISO 5660 GB/T 16172 Cone Calorimeter Heat Release Rate Flammability Testing Equipment
The Cone Calorimeter is the most significant bench scale instrument in the field of fire testing.
Heat release is the key measurement required to assess the fire development of materials and products. Traditionally it has been very difficult to measure and more recently full scale testing of items (e.g. furniture) has been possible by burning these articles and measuring the evolved heat using a technique called oxygen depletion calorimetry.
The Cone Calorimeter has been produced to meet all existing Standards (including ISO 5660, ASTM E1354, ASTM E1474, ASTM E1740, ASTM F1550, ASTM D6113, CAN ULC 135 and BS 476 Part 15) and can also be purchased in modular form so that those laboratories with particular interests such as heat release, mass loss, smoke production, etc. can initially purchase the sections they require and later add further instrumentation into the same cabinets in order to complete a full specification instrument. This is just one of the advantages of the Cone Calorimeter.
Combustion product stream through the oxygen concentration of the oxygen consumption and calculate the heat release rate, heat release rate of the material is also the material properties of the combustion products of the combustion burner of the most important parameters, more accurately measure the material during combustion heat release rate, for predicting fire hazard prevention and fire-retardant treatment is extremely important.
