The hottest parts of the tested Westinghouse WH7500E generator while operating was found to be the exhaust pipe
and areas of the muffler near the exhaust outlet. The
temperature of these locations was observed to be as high
as 270°C (as shown to the right). It can be assumed that
these areas would be hotter at higher ambient
temperatures, so a temperature approximately 30°C higher
was used for auto-ignition determination.
Auto-Ignition Resistance Testing GenTent Fabric, Thread and Velcro®
A thermocouple attached to an Omega HH309 Data Logger
Thermometer was secured to a 6” x 6” x 1/4” steel plate with
a 500 gram weight. The plate was then heated to
approximately 300°C before a coupon approximately 2” x 3”
of sample GenTent skirt material was placed near the
center of the hot steel plate.
The sample coupon very quickly began to melt and produced a small amount of smoke, but did
Auto-Ignition Resistance Testing GenTent Clamp and Rubber Sleeve
A thermocouple attached to a Omega HH309 Data Logger Thermometer was secured to a 6” x 6” x
1/4” steel plate with a 500 gram weight. The plate was then heated to approximately 300°C before a
set of clamp assembly was placed near the center of the steel plate. The set of clamp was
disassembled to three parts (metal parts were removed) and randomly placed on the heated plate
since each part seemly made by the same material. Except some contact area with the heated plate
were melted, no ignition on any tested part was observed during the test.
