Significance and Use
5.1 The determination of the carbon number distribution of petroleum-based waxes used in synthetic equestrian tracks is useful for characterizing the overall molecular composition to aid in binder selection and replenishment. The test data is also very useful for comparing carbon number distributions between different binders and monitoring an existing track binder as it ages over time. The oil extracted from the wax can also be analyzed by this method. Track surface maintenance decisions can be aided by the results of this test.
1.1 The slack waxes typically used in equestrian surfaces comprise a blend of different waxes and oils, with various hydrocarbons, chain lengths and structures.
1.2 The blend of wax and oil determines the mechanical properties of the surface material, as well as the response of the wax to temperature. The combination of lower and higher carbon weight materials, oil content, and hydrocarbon structures also controls how the wax will endure over time. As the wax ages, it is expected that lower density components will be lost at a higher rate than higher density materials.
1.3 The gas chromatography (GC) test is used to determine the carbon number distribution in extracted wax samples for both normal and abnormal hydrocarbons (linear vs. non-linear carbon chains). This procedure is outlined in Test Method . GC testing utilizes a chromatograph with a flame ionization detector and column.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 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.
