Guide Information for Fire-resistance Ratings

603.11704.11

GENERAL

This category covers spray-applied fire-resistive materials (SFRM) investigated for use in fire-resistance designs as detailed in Fire-resistance Ratings - ANSI/UL 263 (BXUV). SFRMs typically consist of one or more binders, aggregates and fibers. The materials are either mixed with water to form a slurry and conveyed through a hose to a nozzle where compressed air is typically used to disperse the material into a spray pattern, or are conveyed by low-pressure air through a hose to a nozzle where the material is mixed with atomized water and sprayed. The mixing and application instructions are printed on each bag of SFRMs.

Surfaces on which the SFRMs are applied should be free of dirt, oil and loose scale. The minimum thickness and density information specified in the design text must be followed to obtain the specified rating. The test method used to investigate the SFRMs is specified in the design text.

Regulations governing the application and use of the SFRMs have been promulgated by various governmental agencies. Authorities Having Jurisdiction should be consulted to determine local requirements.

Unless specified in the design text as being suitable for exterior-use application, SFRMs investigated to ANSI/UL 263, "Fire Tests of Building Construction and Materials," and ANSI/UL 2079, "Tests for Fire Resistance of Building Joint Systems," are intended for interior-use application only. Materials covered under this category may also use a topcoat material covered under Topcoats for Use in Fire-resistive Applications (XKXC2) as shown in the individual designs.

For SFRMs investigated to ANSI/UL 1709, "Rapid Rise Fire Tests of Protection Materials for Structural Steel," the SFRMs 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. SFRMs investigated to ANSI/UL 1709 can be used in optional environments when indicated in the individual certifications.

In addition to investigations in accordance with ANSI/UL 1709, where indicated in the individual certifications, SFRMs have been tested in accordance with "Jet-Fire Resistance Test of Passive Fire Protection Materials" (1996), published by the Health and Safety Executive of the United Kingdom. These SFRMs have demonstrated an ability to limit the time for the identified structural shape to reach 900°F during a jet-fire exposure for the specified time duration.

To investigate the influence of the environments, the system, including the SFRMs, 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 either ANSI/UL 263 or ANSI/UL 1709, depending on the scope of the investigation. 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 (1) fire tests on exposed samples and (2) fire tests on samples that were not exposed to the simulated environments.
