1.1 这些试验方法包括《联邦法规和术语规范》中规定的松节油取样和试验程序 D804型 这些测试方法也用于大多数松节油的主要成分蒎烯的取样和测试。 1.2 这些测试方法主要测量松节油和蒎烯的物理性质，而不是化学性质。由于松节油和蒎烯目前主要用作生产树脂和合成有机化学品的化学原料，因此化学成分也非常重要。 因此，通过气相色谱法测试松节油和蒎烯的化学成分在很大程度上取代了这些测试方法。（参见测试方法示例 第6387页 .) 1.3 以英寸-磅单位表示的值应视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准值。 1.4 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建立适当的安全、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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 3.1 本标准中所述的测试程序是在松节油主要用作溶剂时制定的。然而，目前，松节油（和蒎烯）的主要用途是作为生产树脂和合成有机化学品的原料。 因此，松节油和蒎烯的化学成分极为重要，除了这些测试方法中描述的测试外，还需要进行测试，以充分表征松节油和松节油。测定松节油（和蒎烯）化学成分最常用的技术是气相色谱法（见试验方法 第6387页 ).

1.1 These test methods cover procedures for sampling and testing turpentine, as defined by the Code of Federal Regulations and Terminology D804 . These test methods are also used for the sampling and testing of pinenes, the major components of most turpentines. 1.2 These test methods primarily measure the physical rather than the chemical properties of turpentines and pinenes. As turpentines and pinenes are currently used chiefly as chemical raw materials for the production of resins and synthetic organic chemicals, chemical composition is also very important. Consequently, testing the chemical composition of turpentines and pinenes by gas chromatography has displaced these test methods to a large extent. (See for example Test Methods D6387 .) 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 test procedures described in this standard were developed when the chief use for turpentine was as a solvent. Currently however, the chief use for turpentine (and pinenes) is as raw materials for the production of resins and synthetic organic chemicals. Thus the chemical composition of turpentines and pinenes is extremely important and tests, in addition to the ones described in these test methods, are required in order to fully characterize turpentines and pinenes. The most widely used technique for determining the chemical composition of turpentines (and pinenes) is gas chromatography (see Test Methods D6387 ).
