Fire in tyres. Vehicle element exposed by flames from the burning tyres.

Heat release rate and response of vehicles:

Vehicle element exposed by flames from the burning tyres. At a request from Directorate for Fire and Explosion Prevention and Swedish Rescue Services Agency, SINTEF NBL was asked to establish a programme in connection with fire in tyres on vehicles transporting substances and articles of class 1.

The test programme was developed in order to decide the heat release rate from burning tyres, and the response of vehicles when exposed to a fire in the tyres. The effect of a heat shield between the tyres and the vehicle should also be revealed. The response of the vehicle should be evaluated by measuring of temperatures inside the vehicle, and by occurrence of openings through wall and floor sections.

The tests were performed in SINTEF NBL's large scale fire test hall under controlled temperature and ventilation conditions.
