1.1 碳氢树脂工业继续从天然衍生材料的替代产品来源发展到没有天然衍生对应物的工业材料。随着行业特征的变化，各种制造业参与者引入的术语导致制造商和消费者之间的混淆。本术语标准旨在缓解这种混淆，并促进碳氢树脂行业术语的标准使用。 1.2 主要来自天然萜烯馏分的树脂受D01.34管辖。 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。

1.1 The hydrocarbon resin industry continues to evolve from a source of replacement products for naturally-derived materials to industrial materials that have no naturally-derived counterparts. Along with this changing character of the industry, various manufacturing participants have introduced terms that have led to confusion among both manufacturers and consumers. This terminology standard is intended to alleviate that confusion and promote standard usage of terms in the hydrocarbon resin industry. 1.2 Resins derived principally from natural terpene fractions are under the jurisdiction of D01.34. 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.
