The report describes the work done to prepare and certify a reference material (CRM 112) for the determination of aromatic hydrocarbons in tubes containing tenax powder (used for active sampling from air followed by thermal desorption). The certified mass of each component in one tube is: Benzene : (1.053 +/- 0.014)microg, Toluene : (1.125 +/- 0.015)microg, and M-Xylene: (1.043 +/- 0.015)microg. These values were calculated on the basis of analyses in 10 laboratories and are in excellent agreement with the values calculated from the preparation data.
