Resolution 6 of the 15th CGPM (1975)
Étalons électriques (poursuite des recherches pour améliorer l'exactitude de la réalisation des unités)
The 15th Conférence Générale des Poids et Mesures (CGPM),
having examined the current experiments designed to realize the ampere, the ohm, the volt and the farad with greater accuracy, as well as the related experiments on the use of the Josephson effect and of the gyromagnetic ratio of proton,
recommends that these experiments be pursued actively,
asks the Comité International des Poids et Mesures to coordinate this work and to organize intercomparisons, not only of the various quantities with direct current, but also of the electromagnetic quantities at high frequencies.
