1 ) THE UL TEST REFERENCED IN 28.2.1 – This paragraph applies the test method described as the UL Flame Exposure (smoke measurements are not applicable) in the Standard for Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables, UL 1 685, to cable that is surface marked or designated by a marker tape as ″CL3 ″ or ″CL2 ″. For compliance, this test damages less than 8 feet (244 cm) of cable.
2) THE FT4/IEEE 1 202 TEST REFERENCED IN 28.3.1 – This paragraph applies the test method described as the FT4/IEEE 1 202 Type of Flame Exposure (smoke measurements are not applicable) in the Standard for Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables, UL 1 685. This test differs from the UL test in loading (more cables are used, with small cables bundled, and the spacing between cables is limited), burner angle, and failure criterion. For compliance, this test damages less than 1 50 cm (59 in) of cable. A cable that complies either is not marked or it bears the designation ″FT4/IEEE 1 202″ or ″FT4 ″ legible on or through the outer surface or on a marker tape [see marking in 47.1 (i)].
d) TYPE CL3X and CL2X CABLES – Type CL3X and CL2X cables comply with the VW-1 vertical-specimen flame test. The cable is not marked ″VW-1 ″.
e) TYPE PLTC CABLE – Type PLTC tray cable complies with a 70,000 Btu/h (20.5 kW) vertical-tray flame test. The cable manufacturer chooses the test in (c)(1 ) or (c)(2). This test is applied to cable that is surface marked or designated by a marker tape as ″PLTC ″.
1 .7 The overall jacket on Type PLTC cable is a ″gas/vapor-tight continuous sheath″ in the sense discussed in sections 501 .1 5 (D) and 501 .1 5 (E) of the National Electrical Code, ANSI/NFPA 70. Cables that are surface marked ″-ER″ are for use as exposed runs between a cable tray and utilization equipment where the cables are continuously supported and protected against physical damage using mechanical protection such as struts, angles, or channel.
1 .8 With certain exceptions, as noted in 1 .9, Type CL3X and CL2X cables are required by the NEC to be used with protection such as raceway. The Type CL3 and CL2 and other cables covered in these requirements that are not required by the NEC to be used in raceway are capable of use without the physical protection of raceway but may be pulled into conduit or installed in other raceway.
1 .9 Type CL3X and CL2X cables are limited by the NEC to use in unconcealed spaces in which the exposed length of cable does not exceed 1 0 ft or 3.05 m, and in raceway. These NEC limitations do not apply to Type CL3X and CL2X cables that are smaller in diameter than 0.25 in or 6.35 mm and are used in a one-, two-, or multi-family dwelling.
