New ultralow sulfur B5 diesel Reference Material available

The Institute for Interlaboratory Studies (iis) did prepare a new Reference Material. The material can be used for quality control purposes for various determinations on ultralow sulfur diesel. The Reference Material can be ordered in quantities of 100 ml. The certified parameters have passed strict statistical assessment.

During the interlaboratory studies of September/October 2007 (iis07G04) with 156 laboratories in 69 different countries, the candidate Reference Material has been certified for various determinations that are all used for diesel testing in accordance with the latest version of EN590. The assigned values and its uncertainties are presented in the following table:
