  • Certification Report, Certification of the sulphur mass fraction in three commercial petrol materials, Certified Reference Materials ERM-EF211, ERM-EF212, ERM-EF213

Abstract

Three petrol reference materials were certified for their total sulfur content in support of Directive 2003/17/EC of the European Parliament and of the European Council, which stipulates that petrol with a maximum S content of 10 mg/kg must be available in all member states by 2009. Commercially available petrol was obtained and filled into borosilicate ampoules without further treatment.
Homogeneity of the materials was tested and no heterogeneity was detected for two of the materials, whereas minor heterogeneity was observed for the third material. Stability of the materials was tested for 8-12 months at 60 Degree Celsius and no degradation was observed.
Characterisation was based on isotope-dilution mass spectrometry (IDMS) applied as primary method of measurement by three European metrology institutes and certified values were assigned using all results. The certified uncertainties include contributions of (potential) heterogeneity, potential degradation as well as characterisation. The final assigned values are:
ERM-EF211: 48.8 plus/minus 1.7 mg/kg
ERM-EF212: 20.2 plus/minus 1.1 mg/kg
ERM-EF213: 9.1 plus/minus 0.8 mg/kg
The materials are available from IRMM (ERM-EF211), LGC (ERM-EF212) and BAM (ERMEF213)
