Low Flame and Smoke CPVC Products

New testing, conducted recently by Harvel Plastics, Inc. at Underwriter’s Laboratories, proves that the company’s CPVC pipe and duct have exceptionally low flame spread and smoke development ratings when tested to ASTM E-84 Steiner Tunnel Testing (UL 723). The largescale burn testing was carried out on Harvel’s currently ULC Listed CPVC piping products for comparative data.

Harvel® CPVC piping has improved fire performance properties over PVC piping and other plastics due to the presence of additional chlorine atoms on the polymer molecule.

The tests demonstrate that Harvel CPVC pipe cannot be the ignition source of a fire; the pipe will not sustain burning; it must be forced to burn due to its high limiting oxygen index; the pipe is considered self-extinguishing: It will not burn unless a flame is constantly applied and stops burning when the ignition source is removed; the pipe has a low heat of combustion: much less than wood and other types of plastic.

Harvel is the only pipe manufacturer that has tested CPVC piping to ASTM E-84. Additional information on the testing can be obtained by contacting Harvel’s Technical Service Department.

Harvel CPVC pipe is available in Schedules 40 and 80, industrial pipe sizes, 1/4” through 24” diameters. Harvel CPVC duct for industrial hot corrosive fume and drain handling systems is available in 6” through 24” diameters.
