The [[International Organization for Standardization]] (ISO) and [[International Electrotechnical Commission]] (IEC) were partners in developing the standards, incorporating them into the [[Open Systems Interconnection]] suite of protocols.  '''ISO/IEC 9594''' is the corresponding ISO/IEC identification.
