Reaction-to-fire tests for façades — Part 1: Intermediate-scale test

ISO 13785-1:2002 specifies a screening method for determining the reaction to fire of materials and constructions of façades or claddings when exposed to heat from a simulated external fire with flames impinging directly upon a façade. It is intended for use by producers to reduce the burden of testing in ISO 13785-2:2002 by eliminating those systems that fail the tests described in ISO 13785-1:2002. The test method consists of observing the behaviour of the façade panel construction to fire and the resulting flame spread on or within the façade construction. This test method is applicable only to façades and claddings that are not free standing and that are used by adding to an existing external wall. This test method also is applicable only to vertical elements and is not applicable to determining the structural strength of the façade or cladding.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with
