(2) The material of which any balustrade, decking or skirting board of an escalator or travolator in station premises is constructed, and the material of which any display panel for advertisements or notices in an escalator shaft in the premises is constructed, shall offer adequate resistance to the spread of flame over the surface of the material and shall have, if ignited, a reasonable rate of heat release.

(c) as offering adequate resistance to the spread of flame over its surface and having a reasonable rate of heat release if the material or, where it is bonded throughout to a substrate, the material combined with the substrate, is of such a nature that it would comply with the test criteria set out in relation to Classs 1 in British Standard 476: Part 7: 1987 and, when tested in accordance with British Standard 476: Part 6: 1989, would have an index of performance (I) not exceeding 12 and sub-index (ii) not exceeding 6.
