- Abstract
- The flame test in the Institute of Electrical and Electronics Engineers (IEEE) Standard 383 was investigated. The investigation was to develop possible modifications in test equipment and test procedure that would increase the repeatability of results and provide additional information useful in assessing cable system performance in response to a real fire. Several fire experiments were conducted varying different test parameters. The experimental data were analyzed and modifications of both test equipment and test procedure were developed to increase repeatability. These modifications ere: An enclosure for the sample, defining cable damage; cable fastening and the cable tray to be used; establishing tolerances for exhaust of the enclosure; starting temperature of the ambient air cable sample; location of the burner and the flow rates of fuel and air into the burner. Suggested also, was to report the maximum flame height versus time and the rate of heat released versus time as additional information that would be useful in assessing cable system performance.
