UNE 21123 standard refers to the design and cross-sectional area specifications for cables used by utilities on power distribution circuits with voltage ratings up to and including 600/1000V (0.6/1kV). UNE standards are released by AENOR (Asociación Española de Normalización y Certificación), the Spanish Association for Standardisation and Certification. As AENOR is a member of ISO, IEC, and CENELEC, many of its standards are harmonized with European and international conventions.

NEK TS 606 is the Norwegian offshore industry technical specification (TS) covering a range of power, instrumentation and earth cables that are halogen free and/or MUD resistant, protecting them against the type of hydrocarbon-laden drilling liquid used in drilling operations which can have an adverse effect on cable sheathing materials. Originally published in 1993 by the Norwegian Electrotechnical Committee (NEK) as a successor to the 'Recommended Practice for Specification of Cables' of the Norwegian Oil Industry Association, NEK 606 has evolved to become an internationally accepted standard for offshore cable applications.
