(1) The tests should be performed in accordance with ASTM E-119 and the following conditions.
(2) The cables used in the test should include the caole insulation materials used in :ne facility.
(3) The test sample should be representative of the worst case configuration of cable loading, cable tray arrangement, anchoring and penetration fire barrier size and cesign.
The test samole should also be representative of the cable sizes in the f acility.
Testing of tne penetration fire barrier in tne floor configuration will qualify the fire stoc for use in the wall configuration also.
(4) Cables penetrating the fire barrier snould extend at least three feet on the unexposed sice and at least one foot on ne exposed side.
(5) The fire barrier should be tested in both directions unless the fire barrier is symmetrical.
(5) The fire barrier should be tested-with a pressure differential across it tnat is ecuivalent to the maximum pressure differential a fire carrier in the plant is expectec to experience.
(7) The temperature levels of the cable insulation, caule concuctor, caole tray, conduit, and fire stop material snould be recordec for the unexposed side of the fire barrier.
(3) Acceptance Criteria - The test is successful is:
(a) The caole penetration fire barrier has withstcoc tne fire encurance test without passage of flame or ignition of c3 Dies on the unexposed side for a period of three hours, and (b) The temcerature levels recorded for the unexcosea side are analyzed and demonstrate that the maximum temcerature is sufficiently below the cacle insulation ignition temcerature, and (c) The fire barrier remains intact and does not allow projection of water beyond the unexposec surface curing the nose stream test.
