A series of tests have been carried out in the Cone Calorimeter (ISO DIS 5660) on 11 materials. The tests were a part of a joint Nordic fue research programme, EUREFIC and were performed at SP, Sweden and at Dantest, Denmark. The purpose of the tests was to gain sufficient data for use in the development and validation of a calculation model for scaling smale scale test results from the Cone calorimeter to large scale test results of the room fire test, NT FIRE 025 (ISO DIS 9705). The results have been reported to a data base developed within EUREFIC, the so called DCS. DCS stands for Data Converting System.
