Some of the data we ask for

• Where and when was the heat flux gauge
  calibrated?
• What is W/cm2 range of the gauge?
• What is the OSU brand?
• What is the Gauge brand?

Recommendations

• Develop a new panel optimized to have a good peak
  time to heat flux correlation
• Use an IR imager to characterize heat loss of
  OSUs
• Visit other labs, especially the outliers to gain
  understanding. Bring the IR imager
• Develop a finite element analysis model of the
  OSU to better understand significant variables

21
Recommendations (cont.)

• Extend calibration equilibration time from 2
  minutes to 3 minutes per step. Use average of
  1L/Min steps before and after each increase

Recommendations (cont.)

• Extend calibration equilibration time from 2
  minutes to 3 minutes per step. Use average of
  1L/Min steps before and after each increase
• Re-establish OSU QA task group. Especially need
  members willing to participate in mini round
  robins within the group, collect data on more
  operational parameters, and be willing to
  participate in exchange visits.
