ISO International Standard

This document specifies a method of testing the reaction-to-fire properties of an intermediate-scale, box-shaped structure made up of sandwich panels. This test method is a screening method intended for use by producers to reduce the burden of testing in ISO 13784–1, especially with respect to the occurrence of flashover.

This test method is not applicable to determining self-standing capability during fire, which is instead examined using ISO 13784–1 or ISO 13784–2.

This method is not intended to evaluate the reaction-to-fire performance of facades, or the fire resistance of a product, which can be tested by other means.
