In 2016 the JRC-G.2/METRO team has contributed to standardization of methods developed at JRC for nuclear mass spectrometry in various ways. Firstly, in early 2016 the ASTM standard document for the modified total evaporation (MTE) method, written by S. Richter (JRC-G.2/METRO) with assistance from S. Mialle (JRC-II G.6, formerly JRC-G.2) and K. Mathew (LANL, US-DOE), was published with designation ASTM C1832-16. Secondly, during the year 2016 the revision of the ASTM standard document for the so called "classical" total evaporation (TE) method for Thermal Ionization Mass Spectrometry (TIMS) was prepared and submitted to the C26 committee "Nuclear Fuel Cycle" at ASTM-International. The document contains a detailed description of the TE method for U and Pu measurements, which was originally developed at JRC in the late 1980s. S. Richter from JRC-G.2/METRO contributed to the revision of ASTM 1672 in particular to the newly defined requirements for calibration and quality control for TE measurements, as well as by providing new algorithms for uranium and plutonium concentration measurements by IDMS (Isotope Dilution Mass Spectrometry). After review by the C26-05 sub-committee and discussions at ASTM meetings the final draft revision of C1672 is submitted for a concurrent review by the sub-committee C26-05 "Methods of Test" and the C26 main committee in fall 2016.
