Self-standing Compartment Fire Tests on Sandwich Panels

Abstract

Evaluation of the fire performance of building materials is being conducted in Japan in accordance with ISO 5660-1. There is concern that sandwich panels containing combustible cores can pass certain classification criteria based on this small scale test even though they could be ignited and burn in actual fires including flashover. Within ISO/TC92/SC1, the ISO 13784-1 test addresses the evaluation of self-standing sandwich panels, but it is difficult to be routinely performed. This study proposes an intermediatescale self-standing box test that a) has the same configuration as the ISO/TS17431 box test and b) compares this new proposed test with the ISO 13784-1 test both conducted for the first time in Japan in this program. A correlation between these two test methods (the new box test and ISO 13784-1) is also presented.
