Increased knowledge about fire protection

Over the past few years, the Petroleum Safety Authority Norway (PSA) has carried out a project regarding fire protection. The purpose of the project has been to develop a testing method for determining thermal properties of passive fire protection materials. The project report is now completed.


The main objective has been to obtain temperature-dependent thermal data for passive fire protection materials to be able to perform fire-technical calculations of application thickness. This is particularly challenging for swelling materials where the K value varies during heat exposure.

The report proposes a method which includes a test oven and mathematical analyses of the sample to determine the thermal properties.

The plan is now to construct a test oven and test the proposal. Furthermore, we are considering proposing a joint industry project for the future work.

The testing method and the results of the project so far will be presented at a conference in Italy in March.

The project has been carried out in cooperation with Petrell AS and the Norwegian Fire Research Laboratory in Trondheim.
