NFPA 262 PDF

Make more accurate assessments of smoke and fire spread in plenums using the test method presented in NFPA 262.

Referenced by both NFPA 90A, Standard for the Installation of Air-Conditioning and Ventilating Systems, and NFPA 70^®, National Electrical Code^®, and vital for testing labs, NFPA 262, Standard Method of Test for Flame Travel and Smoke of Wires and Cables for Use in Air-Handling Spaces, presents a test procedure to evaluate the potential for fire spread along cables and wires housed in a plenum or other environmental space.

The test method lets you measure and record both flame travel distance and optical density of smoke for:

• Electrical wires and cables that are insulated, jacketed, or both
• Optical fiber cables for installation in plenums and other spaces used to transport environmental air without being enclosed in raceways
