■ ■ Evaluate the ability of an assembly to contain a fire and
maintain its structural integrity, over the period for which it is
to be rated.
■ ■ Measure and evaluate the heat transfer (temperature rise)
through the firestop system’s entire thickness to ensure that
hot-surface ignition cannot occur on the protected side.
■ ■ Evaluate the stability by acceptable performance under the hose
stream test.
