This International Recommendation concerns the metrological controls to which fuel dispensers for motor vehicles shall be submitted in order to verify that their characteristics comply with the requirements of the International Recommendation OIML R 117 Measuring systems for liquids other than water. It does not apply to dispensers for liquefied petroleum gases (LPG). The procedures are intended for testing complete systems. For systems where some of the components have been previously approved, the number of tests may be reduced. The purpose of this Recommendation is to facilitate the recognition of test results among countries. In this way, duplication of tests can be avoided, thereby simplifying considerably the work associated with pattern approval. The standardized test report format for pattern evaluation of fuel dispensers for motor vehicles is given in Annex A.
