This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
====== Significance And Use ======
5.1
Fuel oxidation and other degradative reactions leading to formation of sediment (and color) are mildly accelerated by the test conditions compared with typical storage conditions. Test results have been shown to predict storage stability more reliably than other more accelerated tests. See
Appendix X1
for information on the correlation of test results with actual field storage.
5.2
Because the storage periods are long (4 weeks to 24 weeks), the test method is not suitable for quality control testing, but does provide a tool for research on storage properties of fuels.
5.3
Because environmental effects and the materials and nature of tank construction affect storage stability, the results obtained by this test are not necessarily the same as those obtained during storage in a specific field storage situation.
