1.1本试验方法涵盖了通过季戊四醇树脂酸酯（PKP）滴定法测定油墨配方中使用的石油的相对溶解性的程序。 1.2本试验方法适用于初始沸点超过90的石油 o C和低于500的干点 o C通过方法D86测定。 1.3本试验方法以及通过试验方法D445确定的粘度测量，用于确保石油的成分一致性。它还可以区分具有相同粘度的加氢处理油和非加氢处理油。 1.4本试验方法包括使用美国职业安全与健康管理局（OSHA）- 指定易燃化学品戊烷。有关具体的危险信息和使用指南，请参阅供应商的材料安全数据表。 1.5 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和健康实践，并确定监管限制的适用性。 具体危险说明见1.3。 ====意义和用途====== PKP值表示高芳烃或高环烷含量，或两者兼有，这有助于提高油的相对溶解性。

1.1 This test method covers a procedure for determining the relative solvency of petroleum oils used in ink formulations by a pentaerythritol ester of resin acids (PKP) titration. 1.2 This test method is applicable to petroleum oils that have an initial boiling point over 90 o C and a dry point under 500 o C as determined by Method D86. 1.3 This test method, along with viscosity measurements as determined by Test Method D445, is used to ensure the compositional consistency of petroleum oils. It can also differentiate between hydrotreated and non-hydrotreated oils that have the same viscosity. 1.4 This test method includes the use of a U.S. Occupational Safety and Health Administration (OSHA)-designated flammable chemical, pentane. Consult the suppliers' material safety data sheet for specific hazard information and guidance relative to use. 1.5 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in 1.3. ====== Significance And Use ====== PKP values indicate high aromatic or high naphthenic content, or both, which contributes to high relative solvency of the oil.
