UL Standard for Safety Fire Test of Insulated Wall Construction
|Publication Date:||9 August 1996|
This test method describes the testing procedures and requirements applicable to insulated wall constructions by use of a standardized large-scale corner test.
The purpose of this test method is to determine the ability of field or prefabricated insulated wall panels to resist the spread-of-flame over a simulated interior wall surface of a building and the ability of the insulating material to resist damage as a result of the fire exposure. This test method is not intended to evaluate the fire resistance afforded by the structural members of the test structure such as columns, beams, girders, bar joists, tie bars, and the like.
These requirements do not cover the evaluation of panels intended for various uses other than as specified in 1.1 for which there are other established test standards as follows:
a) Surface Burning Characteristics Classification - Establishes the comparative burning characteristics of building materials and assemblies by measurement of flame spread over exposed surfaces and the density of the smoke developed during the fire exposure period. This test method is described in the Standard for Test for Surface Burning Characteristics of Building Materials, UL 723.
b) Fire-Resistance (hourly rating) - Establishes hourly fire resistance ratings of building assemblies through large-scale fire exposures under specific loading conditions. This test method is described in the Standard for Fire Tests of Building Construction and Materials, UL 263.
c) Roof-Covering Materials - Establishes performance measurements for coverings relative to resistance to exterior fire spread and penetration. This test method is described in the Standard for Test Methods for Fire Resistance of Roof-Covering Materials, UL 790.
d) Roof-Deck Construction Materials - Establishes performance measurements for roofing systems with respect to resistance to the spread-of-flame and damage from underdeck interior fire exposure. This test method is described in the Standard for Fire Test of Roof Deck Constructions, UL 1256.
A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
