8 Mechanical Damage – Impact
8.1 An Impact Test for all types shall be conducted using the requirements, including sample selection, (cable containing 3 – 14 AWG conductors and 3 – 2 AWG conductors) specified for the Impact Test in the Standard for Metal-Clad Cables, UL 1569 with the exception that the weight of the falling mass shall be 25 pounds (11.34 kg) through a distance of 1 foot (0.31 m) for the tests with the 14 AWG conductors. ITC-HL cables are to be tested only with 14 AWG conductors to represent sizes 22 to 12. ITC-HL cables are permitted to be tested with smaller conductor sizes that represent only the size tested.
9 Crushing Test
9.1 A Crushing Test for all cable types shall be conducted using the requirements specified for the Crushing Test – All Cable, in the Standard for Metal-Clad Cables, UL 1569, with the following modifications.
• The sample for non-ITC-HL cables shall contain 3 – 14 AWG conductors and 3 – 2 AWG conductors.
• The sample for ITC-HL cables is permitted to contain only 14 AWG conductors (to represent all sizes from 22 AWG to 12 AWG) or small conductor sizes to represent only the size tested. • The crushing force is to be 1500 pound-force (6670 N) for the test with the 14 AWG conductors. 10 Flame Test 10.1 The Flame Test shall be performed in accordance with the FT4/IEEE 1202 Flame Exposure Test in the Standard for Fire-Propagation and Smoke-Release Test for Cables, UL 1685, (smoke measurements are not applicable). 10.2 For MC-HL and ITC-ER-HL, the test specimens for the FT4/IEEE 1202 tray flame test are the smallest size (typically 14/3) [equivalent diameter for a cable that is not round is calculated as 1.1284 × (TW) 1/2 , in which T is the length of the minor axis of the cable and W is the length of the major axis of the cable] cable that the manufacturer intends to produce in each construction made. 10.3 For TC-ER-HL, the results using 9-conductor 12 AWG samples are representative of the performance of finished cable of the same construction in all (18 – 4/0 AWG and 250 – 1000 kcmil) sizes. MARKING 11 General 11.1 Cables complying with the requirements of this standard shall be surface marked Type MC-HL, Type “TC-ER-HL” or Type ITC-HL as appropriate, and shall comply with all applicable marking requirements in the Standard for Metal-Clad Cables, UL 1569, the Standard for Electrical Power and Control Tray Cables with Optional Optical-Fiber Members, UL 1277 or the Standard for Instrumentation Tray Cable, UL 2250, as applicable.UL 2225 pdf download.
