The definition, background and derivation are given for a provisional temperature scale, Ehelle provisoire de Temperature de 1976 entre 0.5 K et 30 K, which is intended to alleviate inconsistencies which exist between liquid helium vapour pressure scales and the IPTS-68 and to set an international temperature scale below 13.81 K. The interpolation instruments for realizing this scale are briefly discussed with the reference points.
