1.1 These requirements cover Type ITC instrumentation control cables consisting of two or more current-carrying copper or thermocouple alloy conductors with or without either or both:
1.Grounding conductor(s), bare or insulated, and
2.One or more optical-fiber members, all under an overall jacket.

These electrical and composite electrical/optical-fiber cables are intended for use (optical and electrical functions associated in the case of a hybrid cable) on circuits rated 150 V or less and 5 A or less in accordance with Article 727 and other applicable parts of the National Electrical Code (NEC).

1.2 These cables are rated 300 V and are so marked. Cables for direct-burial are so marked. Jacketed Type ITC cables comply with one of the following 70,000 Btu/h (20.5 kW) vertical-tray flame tests:
1.The UL test referenced in - of these requirements. These paragraphs apply the test method described as the UL Flame Exposure (smoke measurements are not applicable) in the Standard Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables, UL 1685.
2.The FT4/IEEE 1202 test referenced in of these requirements. This paragraph applies the test method described as the FT4/IEEE 1202 Type of Flame Exposure (smoke measurements are not applicable) in UL 1685.
3.For limited-smoke cable, either the UL test or the FT4/IEEE 1202 test referenced in and of these requirements. These paragraphs apply the test methods described in UL 1685 with smoke measurements included. 1.2 revised October 27, 1998
