This paper presents the results of a mini Inter-Laboratory Study (mILS) that is a continuation of earlier work, published in SAE paper number 2014-01-0179 [1]. This work was aimed to improve the capability, precision, and durability of the Ignition Quality Tester (IQT™) and ASTM D6890 [2]/EN15195 [3] Test Methods. The mILS was performed to determine how much the TALM IQT™ Precision Package would improve the precision of four IQT™s, relative to a larger number of IQT™s participating in two separate Fuel Exchange Programs (FEPs). Two of the IQT™s were located at AET and the other two were located at two different external laboratories. All four IQT™s were equipped with the TALM Precision Package. Nine fuel samples from the two FEPs with reference DCN values from 33 to 82 were selected for testing.
