  1. Objectives.  The Plenum Cable Association objectives are as follows:

"The Plenum Cable Association shall endeavor to promote the manufacture, design, and use of cables and wires for use in ceiling cavity plenums and/or raised floor plenums, and shall encourage requirements ensuring that such cables and wires are associated with a high level of fire safety, namely one that is commensurate with the fire hazard and fire risk inherent in the application."

  1. Scope.  The Plenum Cable Association shall address:

            a)  Issues associated with the development and revision of fire test standards intended to measure and describe the response of cables or wires to be used in plenums and of materials intended to be included in plenum cables or wires.


            b)  Issues associated with the development and revision of codes and specifications intended to assess or regulate the use of cables or wires to be used in plenums and of materials intended to be included in plenum cables or wires.


            c)  Issues associated with the development and revision of fire standards intended for analysis and assessment of the fire performance (and the associated fire hazard or fire risk) of cables or wires to be used in plenums, including those suitable for use by regulatory officials, as well as of those intended for the assessment of materials, when such materials are to be used in plenum cables or wires.


            d)  The stimulation and, where appropriate, support of fire-related research; and, the administration and evaluation of fire research programs related to plenum cables or wire activities.


            e)  Identification of means for measuring the hazard or risk associated with fires in plenums, or during the process of extinguishing fires originating in or spreading to plenums, especially when such fires are associated with cables or wires.


            f)  Monitoring of the public need for fire standards, and proposing new standards as appropriate.


            g)  Provision of guidance to the users of fire standards and of codes associated with the use of plenum cables or wires.  Such users may include laboratories performing fire tests, and committees developing codes and standards.
