Similar overlaps exist with BS (British Standards), EN (European) standards, ans AS (Austrialian) standards.
IEC standards are adopted as harmonized standards by other certifying bodies such as BSI (United Kingdom), CSA (Canada), UL & ANSI (United States), SABS (South Africa), SAI (Australia), SPC/GB (China) and DIN (Germany). IEC standards harmonized by other certifying bodies generally have some noted differences from the original IEC standard.
An IEC Standard that is harmonized for European Standards is proceeded by "EN" as an example: IEC 60034 would be EN 60034. "BS" for British Standards.
