Measurement data from full-scale fire experiments of E-mobility Devices on Passenger Railcars

Samples were collected at a rate of 1 Hz. Video and gas concentration measurements were synchronized to the data acquisition system.</p><ul><li><b>Temperature.</b> Temperatures were measured using bare-bead, 1.25 mm (0.05 in), Chromel-Alumel (Type K) thermocouples with an estimated total expanded uncertainty of ±15%.</li><li><b>Heat Flux.</b> Heat flux measurements were obtained using four water-cooled Schmidt-Boelter total heat flux gauges with a typical uncertainty of ±8%.</li><li><b>Gas Concentrations.</b> Six gas concentration sampling ports were located at three locations in the aisle of the railcar, at 0.91 m (3 ft) and 1.51 m (5 ft) heights, and were analyzed via a paramagnetic alternating-pressure oxygen analyzer and a non-dispersive infrared combination carbon dioxide/carbon monoxide analyzer.

The relative expanded uncertainty of the gas sensors was ±1%. An estimated uncertainty of ±12% was applied to the gas concentration measurements to account for non-uniformities in the sampling environment.</li><li><b>Video and Still Images.</b> Video footage was recorded at 4K resolution with cameras at 1.5 m (5 ft) height and at floor level. Still images were captured before and after experiments, as well as during notable events.</li></ul><h3 dir="ltr"><u>Test Summary</u></h3><p dir="ltr"><b>Table 1: Test Summary</b></p><code><pre><code>Code EMV Location of EMV</code><br><code>------------------------------------------------------------</code><br><code>Exp 1 Folding scooter Overhead luggage compartment</code><br><code>Exp 2 E-Bike Luggage rack near rest room</code><br><code>Exp 3 Seated Scooter Wheelchair parking area</code><br><code>Exp 4 Seated Scooter Wheelchair parking area</code></pre></code><h3 dir="ltr"><u>Repository Structure</u></h3><p dir="ltr">This repository contains several subdirectories and file types.
