COOMET.QM-S5 (COOMET project No 576/RU/12) 'Supplementary comparison of national standards in the field of analysis of gas mixtures containing CO2, CO, C3H8 in nitrogen ("automotive" gas mixtures)'
Abstract
The relevance of the COOMET.QM-S5 comparison is founded on tightening of requirements to a control of automobile emissions (realization of environmental standards of EURO 4, EURO-5). Participating laboratories: VNIIM, BAM, BelGIM, Ukrmetrteststandart, KazInMetr. This comparison was carried out in 2013-2014. This supplementary comparison supports CMC claims for: CO2 in the range (4-16) . 10-2 mol/mol; CO in the range (0.5-5) . 10-2 mol/mol; C3H8 in the range (0.01-0.3) . 10-2 mol/mol. Results:
Component CO: All laboratories identified the values of carbon monoxide mole fraction in the gas mixture within +/-0.9134%. Component CO2: All laboratories identified the values of carbon dioxide mole fraction in the gas mixture within +/-0.3042%. Component C3H8: All laboratories identified the values of propane mole fraction in the gas mixture within +/-0.443%. Main text To reach the main text of this paper, click on Final Report.
