Compounds developed specially to meet NFPA 262/UL910

Often found on building material lists, the Plenum cable and plenum wire (CMP) signifies cable that has passed stringent burn testing and is suitable for installation in Air Plenum spaces.

The Air Plenum space defined as the area through which environmental air is transported. Examples of this included space above a suspended ceiling or below a raised floor that does not have closed air ducts for the HVAC system to transport air.

Although local building codes dictate exactly what is required in a local area, the National Fire Protection Association (NFPA) provides a recommendation on a national basis. For Plenum rated cables, this falls under NFPA-262. The UL equivalent standard is the UL-910 standard, which is made up of two primary tests, cable burn properties and smoke density.
