GENERAL

This category covers positive pressure tested gasketing materials for fire doors intended for installation on certified fire doors and/or certified fire door frames or in their thresholds, as specified in the individual certifications. The gasketing material is intended to be installed in accordance with the installation instructions packaged with the material.

Gaskets and edge seals are categorized as follows:

Category G Edge Sealing Systems — Edge seals are gasket materials that have demonstrated their ability to assist the door in meeting the positive pressure fire test requirements. They expand and fill the gaps around the door edges to prevent the passage of hot smoke and gases. These materials are required for Category B Swinging Type Fire Doors, Positive Pressure Tested (GSZN). Edge seals are surface applied to frames or doors. These seals may or may not affect the leakage (smoke) requirements for the smoke ("S") rating. Edge Sealing Systems are either certified for general use on all products in a door type family or limited to individual door manufacturers as noted in the individual certifications. Edge seals that are also smoke seals are denoted as Category G/Category H Edge Seal/Smoke and Draft Control Gasketing in the individual certifications.

Category H Smoke and Draft Control Gasketing — Gasketing materials that are surface applied to a door and frame assembly to comply with the requirements of ANSI/UL 10C, "Positive Pressure Fire Tests of Door Assemblies," and ANSI/UL 1784, "Air Leakage Tests of Door Assemblies." Smoke and draft control gasketing is either certified for general use on all products in a door type family or limited to individual door manufacturers as noted in the individual certifications.

Category J Gaskets — Gasket materials that are added to a door assembly for purposes other than Category G Edge Seals and Category H Smoke and Draft Control Gaskets. They are used for purposes such as weather stripping, sound control, etc. Category J Gasketing Materials have only been investigated to positive pressure with respect that they do not contribute to flaming during the fire test. They have not been evaluated for any contribution for a door assembly to help meet the positive pressure requirements.

Gasketing materials consist of a metal frame or a flexible material, either mechanically secured within a metal frame or housing or applied by means of a pressure sensitive adhesive to the perimeter of the certified fire door and/or certified door frame or installed within their thresholds, as specified in the individual certifications.

The gasketing material can be installed on the certified fire doors at the fire door and/or frame manufacturer's plant or at the job site. Category G materials are materials that assist with doors meeting the positive pressure test requirements. Category H Gasketing Materials for fire doors have been investigated only with respect to determination that the materials do not adversely affect the fire rating of fire doors in which they are installed. Category J Gasketing Materials have only been investigated with respect to determination that the materials do not adversely affect the fire rating of fire doors in which they are installed. Gasketing material identified for use at the meeting edges of pairs of doors is not intended to replace the astragal (if required by the door manufacturer) nor to alter the clearance between doors, as specified in ANSI/NFPA 80, "Fire Doors and Other Opening Protectives," or in the door manufacturer's installation instructions.
