[Building Materials] (Surface-burning Characteristics) Mineral and Fiber Boards, BQXR


See General Information for Surface-burning Characteristics

703.4.1719.1805.1.3

GENERAL

This category covers mineral and fiber boards consisting of proprietary mixes of organic and/or inorganic fibers and binders formed into various sizes and thicknesses and supplied with or without surface coatings or facings. The boards are certified as to surface-burning characteristics as indicated in the individual certifications.

Some mineral and fiber boards are provided with facings that may affect the contribution of combustibles under fire conditions. This effect is determined by testing the sample with a longitudinal butt joint, constructed by slitting the facings or by using a factory or field joint (if applicable).

If the mineral and fiber board is treated, the treatment may be with water-soluble salts which may be affected by repeated exposure to water or conditions that may result in condensation of water.

In some cases, products are certified under the designation "FHC 25/50." This denotes that these products have flame-spread values of 25 or less and smoke-developed values of 50 or less.

The insulating, acoustical, structural, toxicity of the products of combustion and other properties have not been investigated.

The certifications are confined to the materials themselves and do not pertain to the structures in which the materials may be installed.

Authorities Having Jurisdiction should be consulted before installation.

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

ADDITIONAL INFORMATION

For additional information, see Surface-burning Characteristics (BIKT) and Building Materials (AABM).

REQUIREMENTS

The basic standard used to investigate products in this category is ANSI/UL 723, "Test for Surface Burning Characteristics of Building Materials."

In addition to the surface-burning characteristics, where indicated in the individual certifications, unfaced mineral and fiber boards have also been certified to ANSI/ASTM E136 (2012), "Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750°C."

UL MARK

The Certification Mark of UL on the product or on the smallest unit container in which the product is packaged is the only method provided by UL to identify products manufactured under its Certification and Follow-Up Service. The Certification Mark for these products includes the UL symbol, the words "CERTIFIED" and "SAFETY," the geographic identifier(s), and a file number.

Additional Certification Markings

Products covered under this category are additionally marked with the following information:
