CEN/TC 19/WG 30 - Fuel quality monitoring system

This standard specifies a procedure for drawing, from fuel dispensers, samples of petrol and diesel fuel to be used for the assessment of automotive fuel quality in accordance with EN 14274. This standard does not cover the sampling of Liquefied Petroleum Gas (LPG).
NOTE    When petrol is sampled, it is recommended that the pre-treatment of the sample containers and their transportation be set out as in the NOTE in Clause 6.
WARNING: The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems 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.

This European Standard describes a fuel quality monitoring system (FQMS) for assessing the quality of petrol and automotive diesel fuel marketed in any of the Member States within the European Community.
Some basic background ideas behind the FQMS are given in annex A.
Since the specifications for automotive fuels contain climatic related requirements, the FQMS is run twice a year, once during the winter period and once during the summer period. Information about the dates for the summer and winter periods in a specific country are defined in the country's national annex to EN 228 and EN 590. Fuel samples taken during transition periods shall not be included in the FQMS.
For the purposes of this FQMS, grades of petrol that constitute less than 10% of the total amount of petrol dis-pensed in any one country, and grades of automotive diesel fuels that constitute less than 10% of the total amount of automotive diesel fuel dispensed in any country may require separate handling as described in clause 5 of this European Standard.
