method of defining resistant to the spread of fire is for the damage (char length) not to exceed 1.5 m (4 ft 11 in.) when performing the CSA "Vertical Flame Test
— Cables in Cable Trays," as described in CSA C22.2 No.
0.3-M-2001, Test Methods for Electrical Wires and

Cables.

(D) Type CATVX. Type CATVX limited-use community antenna television coaxial cables shall be listed as being suitable for use in dwellings and for use in raceway and shall also be listed as being resistant to flame spread.
FPN: One method of determining that cable is resistant to flame spread is by testing the cable to the VW-1 (vertical-wire) flame test in ANSI/UL 1581-2001, Reference Standard for Electrical Wires, Cables and Flexible Cords.

FPN No. 1: Cable types are listed in descending order of fire-resistance rating.
FPN No. 2: See the referenced sections for listing requirements and permitted uses.

820.182 CATV Raceways. CATV raceways shall be listed in accordance with 820.182(A) through (C).

(A) Plenum CATV Raceways. Plenum CATV raceways shall be listed for use in other spaces used for environmen tal air and shall also be listed as having adequate fire-resistant and low smoke-producing characteristics.

FPN: One method of defining that an optical fiber raceway is a low smoke-producing raceway and a fire- resistant raceway is that the raceway exhibits a maximum peak optical density of 0.5 or less, an average optical density of 0.15 or less, and a maximum flame spread distance of 1.52 m (5 ft) or less when tested in accordance with the plenum test in UL 2024, Standard for Optical-Fiber Cable Raceway.

(B) Riser CATV Raceways. Riser CATV raceways shall be listed for use in risers and shall also be listed as having adequate fire-resistant characteristics capable of preventing the carrying of fire from floor to floor.

FPN: One method of defining fire-resistant characteristics capable of preventing the carrying of fire from floor to floor is that the raceways pass the requirements of the Test for Flame Propagation (Riser) in UL 2024, Standard for Optical-Fiber Cable Raceway.

(C) General-Purpose CATV Raceways. General-purpose CATV raceways shall be listed suitable for general- purpose use and shall also be listed as being resistant to the spread of fire.

FPN: One method of defining resistance to the spread of fire is that the raceway passes the requirements of the Vertical-Tray Flame Test (General Use) in UL 2024, Standard for Optical-Fiber Cable Raceway.
