scope:

This Standard establishes requirements for the performance and installation of gasketing systems including intumescents applied to, or mortised to doors, frames or both. Included are performance tests intended to provide installation guidelines, resistance to smoke and air infiltration, and measure the life and durability of gasketing materials.

Requirements apply to factory or field installed materials.

Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, maintenance and environmental conditions.
