scope:

This European Standard specifies an inductively coupled plasma optical emission spectrometry (ICP OES) method for the determination of sodium, potassium, calcium, phosphorus, copper and zinc contents of diesel fuels, including those containing up to 10 % (V/V) fatty acid methylester (FAME), in the range of x mg/kg to y mg/kg. These six elements are considered as the most essential ash forming metallic elements. NOTE 1 The range of each element is to be confirmed by a Round Robin Test (RRT) being executed by CEN/TC 19. See Foreword. NOTE 2 For the purposes of this European Standard, the term "% (V/V)" is used to represent the volume fraction, f. 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.
