Abstract

The objective of the project has been to find a common Nordic approach on how the new EN test standards on testing of fire resistance of building products should be applied until the CE marking has been fully established.

Due to the wide extent of the work limitations had to be made. Only four of the new test standards have been dealt with within the scope of this project. Focus has been made on assessments, which are of importance for customers, as well as on where differences would occur between the Nordic laboratories.
