10、ieties and the Standards Coordinating Committees of the IEEE Standards Asso-ciation (“IEEE-SA”) Standards Board. IEEE (“the Institute”) develops its standards through a consensus de-velopment process, approved by the American National Standards Institute (“ANSI”), which brings together volunteers re

While IEEE administers the process and establishes rules to promote fairness in the consensus development process, IEEE do

In addition,

14、 IEEE disclaims any and all conditions relating to: results; and workmanlike effort. IEEE standards documents are supplied “AS IS” and “WITH ALL FAULTS.”Use of an IEEE standard is wholly voluntary. The existence of an IEEE standard does not imply that there are no other ways to produce, test, measur

Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of t

However,

23、IEEE does not provide consulting information or advice pertain-ing to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, i

24、t is important that any responses to comments and questions also receive the concur-rence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordi-nating Committees are not able to provide an instant response to comments or questions except in those case

25、s where the matter has previously been addressed. For the same reason, IEEE does not respond to interpretation requests.

All rights reserved.IntroductionThis introduction is not part of IEEE Std 1844-2015, IEEE Standard Test Procedure for Determining Circuit Integrity Performance of Fire Resistive Cables in Nuclear Facilities.Circuit integrity cables are considered passive fire

48、-resistive features when installed in nuclear facilities to meet requirements for protection of safe-shutdown systems or components from the effects of fire. To achieve and maintain safe-shutdown conditions, cables must function under normal conditions and under fire conditions.This standard provide

49、s a test procedure for determining the electrical functionality performance for fire re-sistive cable for specific fire exposure durations and subsequent hose stream application. The purpose of this standard is to establish criteria to determine the circuit integrity performance of a fire resistive cable system. This standard is not meant to determine the flame propagation characteristics or fire stop capability of wire or cable systems. This standard is also not meant to determine the protection afforded to cables by tray covers, conduits, coatings or fire barrier material. T
