1.1 通常用于马术表面的松弛蜡由不同蜡和油的混合物组成，具有不同的碳氢化合物、链长和结构。 1.2 蜡和油的混合物决定了表面材料的机械性能，以及蜡对温度的反应。低碳量和高碳量材料、油含量和碳氢化合物结构的结合也控制了蜡的耐久性。随着蜡的老化，预计较低密度成分的损失率将高于较高密度材料。 1.3 气相色谱（GC）测试用于确定正常和异常碳氢化合物（线性和非线性碳链）提取蜡样品中的碳数分布。试验方法中概述了该程序 D5442 . 气相色谱测试使用带有火焰离子化检测器和色谱柱的色谱仪。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 测定合成马术赛道中使用的石油基蜡的碳数分布有助于表征整体分子组成，以帮助粘合剂的选择和补充。 试验数据对于比较不同粘合剂之间的碳数分布和监测现有轨道粘合剂随时间老化也非常有用。从蜡中提取的油也可以用这种方法进行分析。该测试的结果可以帮助做出轨道表面维护决策。

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 D5442 . 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. ====== 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.
