scope:

This standard sets the fire performance requirements for a Class 1 fire rating of building panel assemblies or interior finish materials with specific height installation requirements and combustibility ratings.

Building panels or interior finish materials shall be tested for installations:

• with a maximum height restriction of 30 ft (9.1 m),

• with a maximum height restriction of 50 ft (15.2 m), or

• without height restrictions (i.e. unlimited height).

The combustibility of a core insulation or interior finish materials shall be identified as combustible or noncombustible.

Building panels or interior finish materials include, but are not limited to:

• Insulated or non-insulated wall and/or ceiling panels with an inert or non-inert facer and combustible core or noncombustible core; and

• Interior finish materials:

o thermoplastic panels,

o thermoset panels, and

o coatings systems and exposed interior insulations.

Any component which may be used in the installation of a building panel or interior finish material such as, fasteners, adhesives, sealants, flashing, substrates, or any other accessories, is considered part of the scope of the product and must be evaluated in conjunction with the product. Any component that may affect the test performance must be included in the test sample construction.

This standard evaluates building panels or interior finish materials for an interior installation application only.

The results of tests conducted under the controlled conditions required by this standard shall not be used to describe or appraise performance under actual fire conditions.

Purpose

This standard states the test requirements for building panels or interior finish materials for interiror appplications where a Class 1 fire rating is needed for wall and/or ceiling constructions.
