Petroleum products — Equivalency of test method determining the same property — Part 100: Background and principle of the comparison and the evaluation of equivalency
ISO/TR 19686-100:2016 describes the procedure for evaluation in order to determine the equivalency of test methods used on a global scale in quality specifications of petroleum products, lubricants, liquid fuels and gaseous fuels for transportation purposes. The result of the assessment on each property is presented in a separate part of ISO/TR 19686. This document is intended to guide laboratories that use one part of ISO/TR 19686 and wish to know if they can also use other parts.
