Guide Information for Fire-resistance Ratings

GENERAL

This category covers mineral and fiber boards investigated for use in fire-resistance designs as detailed in Fire-resistance Ratings - ANSI/UL 263 (BXUV). These boards consist of proprietary mixes of organic and/or inorganic fibers and binders formed into various sizes and thickness. The uses of the boards include forms for gypsum concrete, luminaire protection boxes, roof insulation, membrane ceiling materials, and beam and column protection.

Unless specified in the individual designs and certifications as being suitable for exterior-use application, mineral and fiber boards investigated to ANSI/UL 263, "Fire Tests of Building Construction and Materials," are intended for interior-use application only.

For mineral and fiber boards investigated to ANSI/UL 1709, "Rapid Rise Fire Tests of Protection Materials for Structural Steel," the environments to which a particular system, including the mineral and fiber boards, may be exposed may include a number of optional environmental exposures. However, all systems are investigated for exposure to the following standardized environments: aging, high humidity, salt spray, carbon dioxide and sulfur dioxide air mixture, and wet-freeze-dry cycling.

The individual certifications for mineral and fiber boards investigated to ANSI/UL 1709 may include a list of optional environments for which the boards have been investigated.

To investigate the influence of environments, the system, including the mineral and fiber boards, is applied to either steel plates or structural steel shapes and a selected number of samples are subjected to the environments. After the environmental exposures, samples are subjected to the fire exposure defined in ANSI/UL 263 or ANSI/UL 1709, depending on the scope of the investigation being undertaken. The ability of the system to retain its fire-resistive properties is determined on the basis of a comparative analysis of the fire test data obtained from fire tests on samples that were exposed and fire tests on samples that were not exposed to the simulated environments.

Authorities Having Jurisdiction should be consulted before installation.
