ISO/TR 19686-1:2014描述了ISO为确定石油产品、润滑剂和燃料质量规范中全球范围内使用的测试方法的等效性而进行的评估。ISO/TR 19686-1:2014的重点是确定常压蒸馏特性的标准化试验方法在技术上是否等效。这是为了指导使用一种标准的实验室，并希望知道他们是否也可以向其他标准认证产品。

ISO/TR 19686-1:2014 describes the evaluation executed by ISO in order to determine the equivalency of test methods used on a global scale in quality specifications of petroleum products, lubricants, and fuels. ISO/TR 19686-1:2014 focuses on whether the standardized test methods for determining atmospheric distillation characteristics are to be considered technically equivalent. This is to guide laboratories that use one standard and wish to know if they can also certify product towards the others.
