46.4.2.2
The air intake openings are to be gradually
obstructed by using layers of terrycloth, as defined
in 46.4.2.3, sized at least 2 inches (50.8 mm)
greater than the dimension of the intake opening.
The terrycloth is to be placed over the opening one
layer at a time at 3 minute intervals up to a
maximum of 10 layers, and remain over the
opening for 7-1/2 hours of operation, at which
point ultimate results may be considered
obtained. If draping does not restrict the air
opening, then additional restraint, such as taping,
may be necessary to hold the terrycloth in place.
Tape is not to be used as the means of blocking
the air openings. If the unit is provided with two
separate sets of intake openings (such as the gun-
type dryer), both sets of intake openings are to be
gradually obstructed simultaneously
N/A
46.4.2.3
Fabric used in the test described in 46.4.2.2 shall
be white, 100 percent untreated cotton terrycloth
having a pile weave and a nominal weight of 8
ounces per square yard (271 g/m2)
N/A
46.4.2.4
The same test conditions specified in 46.4.2.1 and
46.4.2.2 shall be applied, but with all temperature
controls simultaneously bypassed and with no
additional layers of terrycloth added after the limit
control operates. When the limit control operates,
the test shall be stopped
N/A
46.4.3
Restricted air outlet test
N/A
46.4.3.1
The tests and the investigation of the results
specified in 46.4.2.1 shall be repeated but the air
outlet is to be blocked, as described in 46.4.3.2
N/A
46.4.3.2
The air outlet is to be gradually obstructed using
masking tape such that approximately 50, 75, 90,
and 100 percent of the outlet opening area is
progressively blocked for 3 minutes at each of the
four positions. For each of three samples, the
location at which the blocking begins (the top, a
side, or bottom) is to progress in the same
direction in which it was started and is to be such
that the limit control will remain in the air flow for
the longest possible time as blocking progresses.
If temperatures cause degradation of the tape, or if
the use of tape would cause deformation of an
outlet nozzle, a metal plate or other material
resistant to combustion may be used to block the
outlet opening. If the final 100 percent blockage
test does not result in interruption of all heater and
motor circuits by a limit control, the test is to be
continued, at 100 percent blockage, for 7-1/2
hours, at which time ultimate results are
considered to be achieved
