Liquid petroleum products. Determination of nickel and vanadium content. Inductively coupled plasma optical emission spectrometry method (ICP OES)1 Scope This European Standard specifies an inductively coupled plasma optical emission spectrometry (ICP OES) method for the determination of nickel content in the range 4 mg kg to 55 mg kg and of vanadium content in the range 4 mg kg to 150 mg kg in fuel oils and residual fuel oils. NOTE 1 Nickel content can be determined from 2 mg kg to 4 mg kg and vanadium content can be determined from 1 mg kg to 4 mg kg. However, the precision was not
