). TEST FACILITY e test was conducted on September 6,1977 at The Kerite Company Fire fest Facility. An American Gas Furnace Company ten-inch wide ribbon
$rner was used to provide the flame source. A direct readout Omega prometer was used in conjunction with a thermocouple to monitor flame
)mperature throughout the test. A laboratory timer was used to measure be duration of the test. The test specimen was installed in the 12-inch wide,
~
cinch deep,11-foot high tray. A 240 volt power source was used to monitor te electrical integrity during the test.

OBJECTIVE The objective of this flame test is to demonstrate that the cable and race-vay, as tested, will not propagate a fire when exposed to an IEEE 383-74.
Iame source.
3.
CABLE AND RACEWAY TESTED Seven conductor No.12 and four conductor No.10,1 KV, polyethylene in-m1ation, PVC jacketed cable, installed in a steel vent tray with a vent rib
- over (to simulate steel vent rib tray).
C. TEST FACILITY
.The test was conducted on September 9,1977 at The Kerite Company Fire rest Facility. An American Gas Furnace Company 10-inch wide ribbon burner was used to provide the flame source. A direct readout Omega pyrometer was as:d in conjunction with a thermocouple to monitor flame temperature through-but the test. A laboratory timer was used to measure the duration of the test.
$he test specimen was installed in a 12-inch wide, 3-inch deep,11-foot high
, ray. A 240 volt power source was used to monitor the electrical integrity t
during the test.
l
- h. TEST PROCEDURE Two layers of 10 foot lengths of test cable were mounted in the tray with no cabic spacings. Each layer consisted of fifteen cables, half from each bkeup, placed in an alternating sequence, for a total of thirty cables. Six cables were chosen at random, three from each layer, and energized with the 240 volt power source.

Test No. 77 VG 58-C Ref. No. 8 The flame source was adjusted so that the temperature was approximately 0
p00 F and approximately 15 inches in length. Under dynamic conditions, the
[11o; wing manometer readings were recorded for both air and fuel in centi-uetsro of water:
Air Fuel
- 4. 5 2.9 These pressures were measured for both air and fuel at the inlet of the pix 2r.
The flame source was placed on the front side of the tray at a 3-inch dis-ance from the cables and allowed to burn for twenty minutes. At the end of senty minutes, the flame source was shut off and the cables allowed to burn atil they self-extinguished or were totally consumed. All pertinent data was Gcorded. The temperatures indicated in +he next section were measured by.
7 s thermocouple located 2 /8" from the burner face.
- 8. TEST DATA *
- 1. Time for specimen to ignite:
Within the first three minutes.
- 2. Time specimen continued to burn after removal of flame cource:
Was not recorded.
3.
Maximum length of sample-damage:
Cable samples totally consumed.
- 4. Time for electrical breakdown:
4 minutes, 45 seconds (Line two to ground) 5 minutes, I second (Line one)
- 5. Heat input 63,000 BTU /hr.
)Because of the severity of the smoke and fire, the test was halted at 15 minutes.
