What is ISO 13784‑2 about ?

ISO 13784‑2 is the second part of a series of documents on fire tests. ISO 13784‑2 specifies a test method for evaluating the reaction-to-fire performance of thermal insulating sandwich panel building systems for large rooms and the resulting flame spread on or within the thermal insulating sandwich panel building construction when it is exposed to heat from a simulated internal fire with flames impinging directly on its internal corner. The test method is not intended for evaluating a product's fire resistance.

ISO 13784‑2 applies to both freestanding and self-supporting and frame-supported thermal insulating sandwich panel systems, but only to wall and ceiling or roof constructions.

Who is ISO 13784‑2 for ?

ISO 13784‑2 on reaction-to-fire tests for sandwich panel building systems is beneficial for:

Manufacturer of sandwich panel
Fire department

Why should you use ISO 13784‑2 ?

The need for improved insulation of buildings has led to the increased use of thermal insulating sandwich panel systems in different parts of the building industry. These sandwich panels with combustible insulation have been involved in several serious fire losses globally.

ISO 13784‑2 deals with a simple representation of a fire scenario involving a thermal insulating sandwich panel system, such as that typified by a local fire impinging directly on the internal face of a thermal insulating sandwich panel building construction. The test method specified in ISO 13784‑2 can be used to provide a large-room scale, end-use evaluation of all aspects of thermal insulating sandwich panel systems, including constructional techniques (supporting frameworks, jointing detail, etc.).

Nevertheless, ISO 13784‑2 provides a means by which a freestanding or frame-supported thermal insulating sandwich panel building construction can be built and evaluated to minimize the fire risk.

What’s changed since the last update ?

BS ISO 13784‑2:2020 supersedes ISO 13784‑2:2002, which is withdrawn.

The main changes compared to the previous edition are as follows:

All drawings have been updated, as some were unclear and views were incorrect.
In the Introduction, the reference to ISO/TR 3814 has been updated to ISO/TS 3814, clarification has been added that this document deals with thermal insulating sandwich panels as well as a widening of the use of products to reflect the current field of applications of sandwich panels.
In Clause 3, the term "constant mass" has been removed, as it is not used in this document, and the term "thermal" in terms of the sandwich panel has been introduced. Terms have been renumbered.
In Clause 8, Ignition source, the wording and locations have been altered to bring them in line with the ISO 19075 series, and cross-references to a figure have been introduced for clarity (no technical consequences).
