In this report is presented the results from a comparison between the existing Nordic fire test methods and classification system for linings and surface finish products, and a proposal for a new classification system based upon the use of the cone calorimeter (IS0/DIS 5660) *) and the room/corner test (ISO/DIS 9705) *). A description and evaluation of the test methods is given. 11 different products have been tested at the Nordic laboratories. The test results from the use of ISO 5657 and NT Fire 004 obtained at SITEF NBL, are presented here. Further, other test results are presented to the extent they are needed for classification of the products. The 11 products are classified according to the existing Nordic classification system, as well as the new system proposed within the EUREFIC programme. A comparison and evaluation of the two classificatin systems is carried out, and it is concluded that future classification system for linings and surface finish products should be based on ISO/DIS 5660 an ISO/DIS 9705.
