(a) Wall and ceiling finishes shall have a flame-spread classification of not greater than 200, American Society for Testing and Materials E84 (refer to Appendix A).
Flame-spread requirements for finishes shall not apply to trim defined as picture molds, chair rails, baseboards and handrails; to doors and windows or their frames; or to materials which are less than one twenty-eighth of an inch in thickness cemented to the surface of walls or ceilings, if these materials have a flame-spread characteristic no greater than paper of this thickness cemented to a noncombustible backing.
(b) All exposed insulation materials, including facings, such as vapor barriers or breather papers, installed within floor-ceiling assemblies, roof-ceiling assemblies, wall assemblies, crawl spaces or attics, shall have a flame-spread rating not to exceed twenty-five, American Society for Testing and Materials E84-1987 (refer to Appendix A).
When such materials are installed in concealed spaces, the flame-spread and smoke development limitations do not apply to the facings, provided that the facing is installed in substantial contact with the unexposed surface of the ceiling, floor or wall finish.
(c) The smoke density shall be not greater than 450, American Society for Testing and Materials E84-1987 (refer to Appendix A).
(d) Tests shall be made in accordance with American Society for Testing and Materials E84-1987 (refer to Appendix A).
