The National Electrical Manufacturers Association (NEMA) published NEMA CG 1-2013 Manufactured Graphite/Carbon Electrodes.
CG 1 is a NEMA standard that adopts the requirements of two international standards—IEC 60529 and IEC/TR 62157—concerning dimensions and designations of graphite and carbon electrodes used in arc furnace applications. All requirements in CG 1-1999 were replaced with requirements from IEC 60529 and IEC/TR 62157.
