leakage is unacceptable. For most tests, the sample rate
will be about 0.15 CFM, thus leakage rates in excess of
0.04 X 0.15 = 0.006 CFM are not acceptable. Record
leakage rates on form no. EPA-5-TP
e)
Once leakage check is satisfactory, unplug probe and set
flow to appropriate rate for test. This should be done in the
minimum amount of time necessary and with the probes in
ambient air. Do not insert probes in tunnel until the start of
the test run. When flow is established, replug probes to
prevent contamination.
Determine optimum load weight by multiplying firebox volume in
cubic feet by 7. This is the load weight on an as-fired basis.
Determine piece size to obtain the requested load configuration
and meet the test load weight criteria. The load should consist of
the following: TO BE DETERMINED
Weigh out test load and adjust weight by shortening all pieces
equally if necessary. Record individual piece load on form no.
