Page 2 EN 13131:2000 Foreword This European Standard has been prepared by Technical Committee CEN/TC 19 "Petroleum products, lubricants and related products", the secretariat of which is held by NNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2000, and conflicting national standards shall be withdrawn at the latest by September 2000. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
Page 3 EN 13131:2000 1 Scope This European Standard specifies a method for the determination of nickel and vanadium by atomic absorption spectrometry in liquid petroleum products with nickel and vanadium contents greater than 5 mg/kg. NOTE For the purposes of this European Standard, the term % (m/m) is used to represent the mass fraction. WARNING The use of this European Standard can 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. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN ISO 3170, Petroleum liquids - Manual sampling (ISO 3170:1988, including Amendment 1:1998) EN ISO 3171, Petroleum liquids - Automatic pipeline sampling (ISO 3171:1988) ISO 648, Laboratory glassware - One-mark pipettes. ISO 4797, Laboratory glassware - Flasks with conical ground joints. 3 Principle The sample is diluted with an organic solvent, the solution aspirated into the flame of an atomic absorption spectrometer, and the absorbance of the characteristic radiation of nickel or vanadium is measured. An acetylene/air flame is used for nickel and a nitrous oxide/acetylene flame for vanadium. Calibration curves are obtained from measurements on calibration solutions of fuels with a known content of nickel and/or vanadium in the same solvent or from measurements on calibration solutions of organometallic compounds in the same solvent. 4 Reagents and materials Use only reagents of recognized analytical grade. 4.1 Xylene, isomer mixture. 4.2 Propan-2-ol.
