Abstract

Certified Reference Materials IRMM-441 and -442 consist of high purity n-heptane and isooctane ampouled in 100 mL units and certified earlier by the National Bureau of Standards, presently National Institute of Standards and Technology, USA, in collaboration with Laboratoire National d'Essais (F) and the Institut Francais du Petrole (F). The certified values were verified by IRMM in 1999. On the basis of these results and on the original certificate, IRMM certified values and uncertainties were determined.
