Conclusion, Round Robins I, II, III, and IV
Decreasing standard deviation trend result of
Standardization of Test Burner/Apparatus
Standardization of Calibration and Test Procedures
Overall Increased Familiarization with Proposed
Test Method

RR III Conclusions
Materials A and E produced most consistent
results, lowest standard deviation
Test data indicated materials C, D, and F more
prone to scatter
Slight modification to data resulted in
significant reduction of standard deviation
Materials A and E used in subsequent Round Robin
