NBS Photometric System Round Robin
Photometric System Round Robin Has Been Completed
• Goal Was To Look At The Scatter The Photometric
System Alone May Have On Fleet Test Data
• Test Included A Linearity Check Of Five Data Points
Using Neutral Density Filters.

NBS Photometric System Round Robin
• Labs Will Be Contacted Identifying Their Lab Codes
And Review Of Data.
• STEP 2
As Follow Up To The Photometric Portion Of The NBS System I
Would Like To Conduct A Round Robin Non-Flaming Test.
• STEP 3 (FINAL STEP)
As Follow Up To The Photometric Portion Of The NBS System I
Would Like To Conduct A Round Robin Flaming Test.
This 3 Step Process Will Hopefully Identify Problem
Areas Fleet Wide.

Chapter 6 Update to FAA Handbook
• 09/29/09: In an effort to provide a constant for
simplifying the calibration factor calculation in
FAR 25, Appendix F, a long standing error was
noted in Chapter 5 (Heat Release Rate Test for
Cabin Materials) of the Handbook. The
constant value located in the equation
(Paragraph 5.6.6) is currently 23.55 and should
actually be 25.31.
• Please verify that your software uses this value.

Maintenance Tips & Reminders
• OSU
– Inspect Cooling Air Manifold Holes / Pipe For
Evidence Of Corrosion
– Inspect Outer Door Seals For Evidence Of
Damage
• NBS
- Remember To Replace The Water Used In
The Pressure Regulator System On A
Regular Basis
- Continually Leak Check NBS Unit Prior To
Testing

Next Steps
• Begin Follow-On Testing To The NBS
Photometric System Round Robin
• Non-Flaming / Flaming
• Look Into How Different OSU Insulation
Densities May Have An Effect On Test Results
• Assist The Flammability Standardization Task
Group As Needed
