Resolution 2 of the 20th CGPM (1995)
Version française
World-wide traceability of measurement standards

    The 20th Conférence Générale des Poids et Mesures,

    considering

  • the increasingly stringent requirements of science, technology and international trade for traceability in measurement at many levels of accuracy,
  • the existence of groups of cooperating national metrology laboratories in different regions of the world,
  • the need to demonstrate world-wide equivalence or traceability of measurement standards among national laboratories and regional groups of cooperating national laboratories,
  • the calibration services of the Bureau International des Poids et Mesures (BIPM) for the national laboratories,
  • the role of the BIPM in carrying out and coordinating world-wide comparisons of standards at the highest level among the national laboratories,
  • the necessary participation of national laboratories in international comparisons,
  • welcomes the trend towards regional grouping of national metrology laboratories as an efficient way of promoting cooperation and regular comparisons of national standards among laboratories, some of which do not participate in comparisons carried out by the BIPM or the Comités Consultatifs,

    recognizes the global advantages of interconnections between the comparisons carried out under the auspices of the BIPM and those of the regional groups of metrology laboratories,

    recommends

  • that national metrology laboratories, in collaboration with the BIPM, ensure that the necessary comparisons between national standards are carried out in sufficient number to demonstrate international traceability of measurement standards,
  • that adequate interconnections are maintained between the comparisons carried out under the auspices of the BIPM and those carried out by the regional groups,
  • and that the results of comparisons carried out by the regional groups be communicated to the BIPM in appropriate form for them to be published by the BIPM and thereby given wide international recognition.
