Graphite having a purity level better than 5 parts per million ‘boron equivalent’ and with a density greater than 1,50 g/cm 3 for use in a “nuclear reactor”, in quantities exceeding 1 kg. N.B.: SEE ALSO 1C107 Note 1: For the purpose of export control, the competent authorities of the Member State in which the exporter is established will determine whether or not the exports of graphite meeting the above specifications are for “nuclear reactor” use. Note 2: In 0C004, ‘boron equivalent’ (BE) is defined as the sum of BE z for impurities (excluding BE carbon since carbon is not considered an impurity) including boron, where: BE Z (ppm) = CF × concentration of element Z in ppm; and σ B and σ Z are the thermal neutron capture cross sections (in barns) for naturally occurring boron and element Z respectively; and A B and A Z are the atomic masses of naturally occurring boron and element Z respectively.

Graphite, other than that specified in 0C004 or 1C107.a., designed or specified for use in Electrical Discharge Machining (EDM) machines.
