The 18th Conférence Générale des Poids et Mesures

recalling and confirming Resolution 3 of the 15th Conférence Générale des Poids et Mesures,

having asked the advice of the Comité International des Poids et Mesures and having approved its decision to proceed with a comparison of the international Prototype of the kilogram with its designated copies ("témoins") and with the working-standard prototypes of the Bureau International des Poids et Mesures,

considering that the Bureau International des Poids et Mesures will then be in a position to organize a general comparison of the national prototypes, a comparison which should begin in the period 1989-1990,

recommends that the laboratories concerned prepare to send to the Bureau International des Poids et Mesures their national prototypes of the kilogram in platinum-iridium for a general comparison of these prototypes.
