1.1 在对砂和纤维表面进行后续材料测试之前，必须对含有蜡油基涂层/粘合剂的马表面进行处理和清洁。注意:对于未涂蜡的表面，跳过此测试。 1.2 所述的蜡分离程序采用索氏萃取去除表面的蜡含量，并计算表面中的粗蜡百分比。程序基于索氏提取方法，该方法已由美国华盛顿州西雅图的Lab/Cor Materials修改，用于马术表面。 2. 1.3 如果存在合成纤维，则在索氏提取之前需要考虑纤维的溶解度，以确保索氏过程不会损害纤维的完整性。 1.4 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。 1.5 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 蜡粘合剂是合成马术表面保持一致性的关键。表面设计用于防止受伤，蜡粘合剂对于确保这一点至关重要。蜡粘合剂的索氏提取是测定合成马术表面中蜡粘合剂含量的有效方法。

1.1 Equine surfaces containing wax-oil based coatings/binders must be treated and cleaned prior to the subsequent material tests described for sand and fiber surfaces. Note: skip this test for surfaces that are not wax coated. 1.2 The procedures described for wax separation employ Soxhlet extraction to remove wax content from the surface and to calculate crude wax percentage in the surface. Procedures are based upon the Soxhlet extraction method, which has been modified for use on equestrian surfaces by Lab/Cor Materials, Seattle, Washington, USA. 2 1.3 If synthetic fibers are present, then fiber solubility will need to be considered prior to Soxhlet extraction to ensure that the Soxhlet procedure will not damage fiber integrity. 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. ====== Significance And Use ====== 5.1 Wax binders are critical for synthetic equestrian surfaces to stay together at consistencies desired. Surfaces are designed to prevent injuries and the wax binders are critical to ensure that this happens. Soxhlet extraction of wax binder is an efficient method to determine the amount of wax binder present in a synthetic equestrian surface.
