Buckeye UltraFiber 500® - 2 Hour U~L. Classified By Michael J Schultz~ PE & Bruce Harding, PhD

Buckeye UltraFiber 500® has been Classified as 2 Hour Fire Resistant when used in D700, D800 and D900 series Floor-Ceiling composite metal deck assemblies as a replacement to welded wire fabric for secondary reinforcement at a dosage rate of 1.0 lb/cy. To obtain this classification, UltraFiber 500® was tested by Underwriters Laboratories in a fire test of a full scale D900 series composite metal deck assembly at their laboratory in Northbrook, Illinois.

The classification testing was performed per acceptance criteria ANSI/UL263 (ASTM El 19 and NFPA 251), "Fire Tests of Building Construction and Materials." The average furnace temperature from which the fire rating was derived is 1000°F at 5 min., l 400°F at 15 min., 1550°F at 30 min., 1700°f at 60 mjn. and 1850°F at 120 min.

Deck assembly with full load applied Fire under deck assembly during test

A detailed description of the assembly, its performance in the fire test and other pertinent details such as specification of materials, Classification coverage and alternate assembly detaiJs are included in UL Report No. R25038 prepared for UltraFiber 500®.

What Does 0700, 0800 and 0900 Mean?

Underwriters Laboratories uses a letter to identify groups of construction (floors-ceilings, beams, columns etc.) and a number to identify types of protection (unprotected, membrane or direct app)jed protection). The letters and numbers that pertain to UltraFiber 500® are identified below:

USE

Page 1 of 2

This category covers fiber reinforcement and concrete additives investigated for use in fire-resistance designs as detailed in the individual certifications and in Fire-resistance Ratings - ANSI/UL 263 (~)-

The fiber reinforcements are intended to control temperature and shrinkage cracking of structural concrete when proportioned and mixed as specified in the individual certifications. These fibers have not been investigated to increase the structural capacity of the concrete/fiber mixture.

Fibers that may also be used as an alternative to the welded wire fabric are identified in the individual certifications. AC! 318, "Building Code Requirements for Structural Concrete and Commentary," and ANSI/SDI Ct.O, "Standard for Composite Steel Floor Deck," should be consulted regarding structural design requirements.

The concrete additives are intended to control temperature and thermal t ransmission of structural concrete when the mix is proportioned as specified in the individual certifications. These additives have not been investigated to increase the structural capacity of the concrete.

Concrete addit ives may be added as specified in the individual certifications. AC! 3 18 and ANSI/SDI Ct.O should be consulted regarding structural design requirements.

Where indicated in the individual certifications, products covered under this category have also been evaluated by ICC Evaluation Service (ICCES).

• Authorities Having Jurisdiction should be consulted in all cases as to the particular requirements covering the installation and use of UL Certified products, equipment, system, devices, and materials.

• Authorities Having Jurisdiction should be consulted before construction. • Fire resistance assemblies and products are developed by the design submitter and have been investigated by UL for compliance with

applicable requirements. The published information cannot always address every construction nuance encountered in the field. • When field issues arise, it is recommended the first contact for assistance be the technical service staff provided by the product

manufacturer noted for the design. Users of fire resistance assemblies are advised to consult the general Guide Information for each product category and each group of assemblies. The Guide Information includes specifics concerning alternate materials and alternate methods of construction.

• Only products which bear UL's Mark are considered Certified.
