Section 27-322
§ 27-322 Tests. Samples of all materials or assemblies of materials
required by this code to have a fire-resistance rating, fire-protection
rating, or flame spread rating, or required to be noncombustible,
fire-retardant treated, or slow burning, shall be tested under the
applicable test procedures specified herein, in accordance with the
acceptance requirements of section 27-131 of article seven of subchapter
one of this chapter. The fire-resistance rating of materials and
assemblies listed in reference standard RS 5-1 may be used to determine
conformance with the fire resistance requirements of this code. In
addition to the performance results, test reports shall give all
technical data pertaining to the nature of the constituent materials,
such as the physical properties, chemical composition and properties,
coefficient of expansion, thicknesses of materials, etc. Except as
listed in reference standard RS 5-1, any assembly using a component
having a structural base of noncombustible material covered with an
integrally manufactured combustible surfacing material, shall be
approved for fire-resistance rating.
