Development of a Test Procedure for Sandwich Panels using ISO 9705 Philosophy Nordtest Project nr 1432-99

Summary, in English

Summary : A number of tests have been performed on different types of sandwich panels. The chosen sandwich panels included most common core materials. Two types of full-scale tests were performed. One set was conducted according to ISO 9705 i.e. tests where the panels were mounted inside a non-combustible room. Another set of full-scale tests was performed using a free standing room under a large calorimeter. This calorimeter allowed HRR and SPR measurements not only until flashover but also after. The tests revealed that such full-scale testing of a free standing room is possible and that it allows for correct mounting of the sandwich panels so that end-use conditions are reliably represented. The results showed that the free standing set-up is slightly more severe than a set-up where the panels are mounted inside the ISO 9705 room. It was, however, not easy to make such a comparison as mounting always differs due to the changed set-up. The major task ofthis project was, however, to investigate the feasibility of testing a free standing set-up with HRR and SPR measurements while retaining the philosophy of ISO9705. This objective was achieved. A small study was also performed on the link between the SBI test and the full-scale tests. It appears to be difficult to establish a link between the SBI test and the full-scale tests with the present procedure.
