The test method can be applied to a wider range of materials, viscosity, and temperature. The precision has only been determined for those materials, viscosity ranges, and temperatures as indicated in Section 12 on Precision and Bias. For jet fuels, the precision of kinematic viscosity has been determined in the range of 2.957 mm 2/s to 5.805 mm 2/s at –20 ☌ and 5.505 mm 2/s to 13.03 mm 2/s at –40 ☌ (as stated in Section 12 on Precision and Bias), and the precision of the temperature at 12 mm 2/s (cSt) has been determined in the range of –38.3 ☌ to –58.1 ☌ (as stated in Section 13 on Precision and Bias).

1.3 The range of kinematic viscosity covered by this test method is from 0.5 mm 2/s to 1000 mm 2/s in the temperature range between –40 ☌ to 120 ☌ however the precision has been determined only for fuels and oils in the range of 2.06 mm 2/s to 476 mm 2/s at 40 ☌ and 1.09 mm 2/s to 107 mm 2/s at 100 ☌ (as stated in Section 12 on Precision and Bias).
