23、ing a Hydrocarbon Pool Fire Test Protocol. There are many circuit integrity tests. Use of these tests can be confusing when trying to apply them to a hydrocarbon fuel fire application. Cables must function under normal conditions as well as under fire conditions. Because hydrocarbon fuel fires have

24、a very steep flame temperature rise, this test protocol is designed to simulate these conditions. The Hydrocarbon Pool Fire Test Protocol (HPFTP) was initially conceived by a major petroleum company in the United States. The information provided herein is based on at least 10 years of practical expe

25、rience in the development of the HPFTP. The IEEE Std 1717TMHydrocarbon Pool Fire Test Protocol was based, in part, on the requirements of API documents to simulate the operation of cables under hydrocarbon fuel fire conditions. Section 5.1.8.1 of API 2218: 2011 specifies that if the control wiring u

26、sed to activate emergency systems during a fire could be exposed to the fire, the wiring should be protected against a 15 minute to 30 minute fire exposure equivalent to UL 1709. API 14 FZ: 2011 recommends that for the specific applications that involve circuit integrity cables to be installed in an

27、 area that may be subject to a hydrocarbon pool fire, the cable should be qualified to withstand a hydrocarbon pool fire per the requirements of API 2218. Because UL 1709 is a test for structural steel and not a test for cables, IEEE Std 1717 was developed to accommodate cable fire test in a UL 1709

28、 furnace test. In addition to the UL 1709 test condition, this standard specifies the circuit integrity monitoring, cable sample selection, and applied voltage as used in UL 2196. Department of Defense (DOD) Standard Practice MIL-STD-3020 also refers to UL1709 for its N-Class division category, whic

29、h is exposure to a hydrocarbon pool fire. In addition to the IEEE Std 1717 cable fire test standard, a fire-rated cables installation guide, IEEE P1810TM“IEEE Draft Guide for the Installation of Fire-Rated Cables Suitable for Hydrocarbon Pool Fires for Critical and Emergency Shutdown Systems in Petr

30、oleum and Chemical Industries” is currently under development at the IEEEs ICC (Insulated Conductor Committee). IEEE P1810 describes fire-rated cable installation methods such as steel materials for the cable tray and supports, supports spacing, steel cable gland, voltage drop, etc. Circuit integrit

31、y cable common applications: Remote operated shutoff valves: power, control, and instrumentation Fire alarms Gas and flame detection Paging systems Fire pumps Emergency systems (i.e., lights, exit signs communication, etc). NOTEThe IEEE Std 1717 furnace test is considered more severe than circuit in

32、tegrity tests with a ribbon burner open flame apparatus such as IEC 60331-11 and BS 6387. Circuit integrity fire tests with a time-temperature curve to 1093 C (2000 F) or higher in 5 minutes without the heat flux requirement of 204 16 kW/m2 (65,000 5000 Btu/ft2-hr) do not represent the conditions of

33、 a hydrocarbon pool fire. Circuit integrity cables are normally used for critical circuits powering and monitoring Remote Operated Shut Off Valves (ROSOV), Emergency Isolation Valves (EIV), and Motor Operated Valves (MOV), which are designed to limit the duration and severity of a fire by shutting o

34、ff the fuel source. These critical circuits are commonly used in chemical and petrochemical plants and refineries. MOVs are Copyright 2012 IEEE. All rights reserved. ixalso common in cogeneration power generating plants and are generally used on the natural gas fuel headers. Circuit integrity cables

35、 can be used to power ROSOVs on natural gas and flammable fluids pipelines to lessen the severity of a natural gas or flammable fluid fire. Older, manually operated valves have caused severe natural gas fires due to the extremely lengthy delays in manually closing the valves during a fire. It is als

36、o the intent of this Group to coordinate with European (IEC) and North and South American (IEEE) groups that have similar interests. Copyright 2012 IEEE. All rights reserved. xContents 1.

Overview 1.1 Scope This standard provides cable and/or system requirements and methods for performing circuit integrity test

44、s on energized low voltage power, control, and instrumentation cables at temperatures and heat fluxes simulating a hydrocarbon pool fire. 1.2 Purpose The purpose of the document is to provide circuit integrity test methodology and performance requirements for cables and/or cable systems which may be

45、 subjected to a hydrocarbon pool fire. This protocol may be useful when selecting cables for applications where circuit integrity is critical to plant shutdown under hydrocarbon fire conditions. It can also be a useful tool in the development of technology to design cables that maintain circuit inte
