ASTM E1354 BS 476-15 Fire Testing Equipment Building Material Cone Calorimeter ISO 9705

ASTM E 1537 Heat Release Rate Tester/Large Calorimeter

Areas of use:

The test method is used for fire technical modelling. The data from the test results can be used for modelling bigger fires. A fire sequence in the ISO 9705 – Room Corner Test and EN 13823 – SBI can for example be predicted using the ISO 5660 method. The cone calorimeter test is also largely used when testing products that are under development. A whole range of different data can be compared in order to eliminate products that will not have the sufficient fire characteristics.
