1.1 本指南涵盖了橡胶应用中使用的合成增塑剂的试验方法。 1.2 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.3 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====== 3.1 合成增塑剂主要是酯类，它们与更极性的弹性体（如CR或NBR）一起使用，以改进加工、调整硬度和改善低温性能。 这些酯可以是单体的，也可以是聚合物的，并且是从许多不同的有机酸中衍生出来的。 3.2 这些试验方法可用于制定和确认橡胶配方中使用的合成增塑剂的质量控制标准。这并不意味着本指南中的试验方法是唯一有意义的方法，但这些试验方法列出了酯增塑剂最常用的特性。这些材料的具体应用可能需要其他参数。

1.1 This guide covers test methods for synthetic plasticizers that are used in rubber applications. 1.2 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. 1.3 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 ====== 3.1 Synthetic plasticizers are primarily esters and they are used with the more polar elastomers such as CR or NBR to improve processing, adjust hardness, and improve low temperature properties. These esters may be either monomeric or polymeric and are derived from many different organic acids. 3.2 These test methods may be used in establishing and confirming quality control standards for the synthetic plasticizers used in rubber compounding. It is not implied that the test methods in this guide are the only ones of significance, but these test methods list the properties most commonly specified for ester plasticizers. Other parameters may be needed for specific application of these materials.
