Commissie
NEC 121 treedt op als nationaal inspraakplatform voor:
• IEC/TC 121 en CLC/SR 121 met beide dezelfde titel ‘Switchgear and controlgear and their assemblies for low voltage’ met als onderwerp en toepassingsgebied:
‘To prepare international standards for low-voltage switchgear and controlgear equipment for industrial, commercial and similar use rated below or equal to 1 kV a.c. and 1,5 kV d.c, electromechanical as well as semiconductor (solid state) equipment. The scope includes open and enclosed separate items of equipment as well as assemblies which are the combinations of items of equipment into complete functional units.’
• IEC/SC 121A en CLC/TC 121A met beide dezelfde titel ‘Low-voltage switchgear and controlgear’ met als onderwerp en toepassingsgebied;
‘To prepare international standards for low-voltage switchgear and controlgear equipment for industrial, commercial and similar use rated below or equal to 1 kV a.c. and 1,5 kV d.c. ’
• IEC/SC 121B en CLC/SR 121B met beide dezelfde titel ‘Low-voltage switchgear and controlgear assemblies’ met als onderwerp en toepassingsgebied:
‘To prepare international standards covering assemblies which are combinations of one or more pieces of low-voltage switchgear and controlgear equipment, not exceeding 1 kV a.c. or 1,5 kV d.c. together with associated control and/or power equipment, measuring, signalling, protective, regulating equipment, etc.’
IEC is leidend. CLC gebruikt daar waar mogelijk IEC-normen.
