This European Standard specifies a method based on inductively coupled plasma optical emission spectrometry (ICP OES) for the determination of manganese content and of iron content, each from about 0,5 mg/l to about 7,0 mg/l in diesel fuels including those containing up to about 10 % ( V/ V) fatty acid methylester (FAME).
The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
Manganese and iron contents higher than 7,0 mg/l can be measured after preliminary dilution of the sample with a suitable solvent. However, the precision has not been established for such a procedure.
For the purposes of this European Standard, the term “% ( V/ V)” is used to represent the volume fraction ( φ) of a material.
