New Protocol To Improve Precision And Reliability When Evaluating Lubricity Improver Additives By HFRR
- Highlighting the typical repeatability and reproducibility limits for the HFRR test method and how this inherent imprecision can be an important factor to consider when evaluating additives to improve diesel fuel lubricity.
- Ensuring a regimented test protocol is followed to maximise the precision of HFRR testing.
- Examples are shown of differences in HFRR performance that can be observed, while not following a strict test protocol, leading to potentially erroneous conclusions regarding an individual additive’s efficacy. These data are then compared with additive performance evaluated under the recommended test protocol, designed to maximise the precision, and give a more accurate assessment of each additive’s performance
