The ITU Radiocommunication Assembly considering a) that ITU technical texts contain a number of terms expressing a relationship between quantities, such as quotient, ratio, coefficient, factor, index, constant, rate, etc., and that their meaning is liable to cause confusion owing to a lack of consistency; b) that the situation is particularly confused owing to the existence of three working languages, as can be seen from such texts as the Provisional list of terms constituting the ITU Terminology base (Termite) published by the ITU in 1996; c) that attempts at standardization have been made in certain countries, in vocabularies recently prepared by the International Electrotechnical Commission (IEC) and the ITU-IEC Joint Coordination Group on Vocabulary (JCG) and in International Organization for Standardization (ISO) International Standards.
