On the realization of the definition of the metre*
The 17th Conférence Générale des Poids et Mesures
invites the Comité International des Poids et Mesures
to draw up instructions for the practical realization of the new definition of the metre,
to choose radiations which can be recommended as standards of wavelength for the interferometric measurement of length and to draw up instructions for their use,
to pursue studies undertaken to improve these standards.
