Introduction
This document supports the existing product standards for factory made underlays for discontinuous
roof coverings and walls by complementing the instructions for mounting and fixing for reaction to fire
testing. The information given in this document comprises exposure to thermal attack, choice of
substrates, consideration and orientation of joints and edges as well as product orientation and fixation
of test specimen, to define unambiguously test conditions in the small-scale burner test and in the single
burning item test.

3.1
underlays
factory-made flexible sheets of plastics, bitumen, rubber or other suitable materials, which are used
underneath roof coverings or behind external wall coverings with the purpose to function as a
secondary water draining layer either installed free-hanging, installed with a ventilated air gap or
installed supported by a substrate
