Note
NMR and MR requirements: Two classifications of electrical performance designated as Type1 and Type2 are given for NMR and MR wires.
Type 1 refers to wires having electrical performance requirements equivalent to small telecommunication cable(<6 pairs)
Type 2 refers to wires with less stringent performance requirements.
