ASTM F3418-20 - Standard Test Method for Measurement of Transition Temperatures of Slack Waxes used in Equine Sports Surfaces by Differential Scanning Calorimetry (DSC)

1.1 The slack waxes typically used in equestrian surfaces comprise a blend of different waxes and oils containing a variety of 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 control how the wax will change over time.

1.3 The differential scanning calorimetry (DSC) test is used to determine temperature transitions and melting range of wax samples. DSC can therefore demonstrate differences in heat flow rates between extracted wax samples. The wax samples are extracted from samples of the surface materials and used in a standard test based on Test Method D4419 (1).2 This procedure involves thermal cycling of samples between –30 and 94 °C using a known control.

1.4 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.

1.5 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.
