What requirements apply to the lining materials used on passenger car enclosures?









Materials used for passenger car linings must meet the following specifications:
(1) Carpeting without padding may be used for interior finishes provided that it has a Class I rating, a flame spread of 25 or less which must include all assembly components except the adhesive. The adhesive must be a slow-burning type.
(2) Slow-burning combustible materials, other than carpet, may be used for interior finishes provided the materials have a Class II rating or better (flame spread of 75 of less), which must include all assembly components other than the adhesive. Materials must be firmly bonded flat to the enclosure and must not be padded. Fabric with spray-type fireproofing must not be installed in elevators.
(a) Equivalent ratings in watts per centimeter squared as derived in the radiant panel test are also acceptable.
(b) .45 watts/cm squared or higher is equivalent to Class I or better.
(c) .22 watts/cm squared or higher is equivalent to Class II or better.
(d) In the radiant test, the higher the number the better the flame resistance.
(e) In the Class I and II system, the lower the number, the better the flame resistance.
(f) Smoke density of materials must be less than 450 when tested in accordance with UBC Standard No. 42.-1.
(3) Certification that the materials and assembly meet these requirements must be submitted to the building official.

Note:
These specifications do not apply to new or alteration permits (see ASME code for requirements).
