This European Standard shall be given the

19、. For this purpose WG1 of TC156 had the task to provide a standard for symbols and terminology to be used by all other working groups of TC156. This standard for symbols and terminology was generated by the different working groups themselves, and WG1 was responsible for the co-ordination between th
20、e working groups and standardization of the symbols and terminology within TC156, which then became compulsory for other WGs to use in their standards. The symbols and terminology in this English standard are numbered and it is intended that these numbers correspond to the German and French translat
21、ion of the standard, so that the different definitions for the same symbol or term can be checked in English, French and German.
