1.1 这些测试方法涵盖了松油的采样和测试程序，适用于通过蒸汽和溶剂过程或破坏性蒸馏从松树树桩中提取的天然松油，也适用于通过萜烯碳氢化合物化学水合获得的合成松油。 1.2 这些试验方法中给出的程序按以下顺序出现: 部分 取样 4. 外貌 5. 颜色 6. 比重 7. 折射率 8. 作文 9 潮湿 10 1.3 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。 1.4 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====== 3.1 这些测试方法中描述的测试程序已使用多年，并强调松油的物理特性，而不是其化学成分。试验方法 D6387 描述一种毛细管气相色谱法，该方法适用于测定松油中的主要成分和次要成分。

1.1 These test methods cover procedures for sampling and testing pine oils, and are applicable to both natural pine oils derived from pine stumps either by the steam and solvent process or by destructive distillation, and also to synthetic pine oils obtained by the chemical hydration of terpene hydrocarbons. 1.2 The procedures given in these test methods appear in the following order: Section Sampling 4 Appearance 5 Color 6 Specific Gravity 7 Refractive Index 8 Composition 9 Moisture 10 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 ====== 3.1 The testing procedures described in these test methods have been in use for many years and emphasize the physical properties of pine oil rather than its chemical composition. Test Methods D6387 describe a capillary gas chromatography method which is suitable for determining both the major and minor components found in pine oils.
