This Technical Report 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. This part of ISO/TR 19686 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.
