The IEC developed their own standards in parallel with the IEEE, with IEC 60625-2-1993 (IEC 625). In 2004, the IEEE and IEC combined their respective standards into a "dual logo" IEEE/IEC standard IEC 60488-2-2004, Part 2: Codes, Formats, Protocols and Common Commands, [11] replaces IEEE 488.2-1992 and IEC 60625-2-1993.

IEC standards cover a vast range of technologies within electrotechnology. The numbers of older IEC standards were converted in 1997 by adding 60000; for example IEC 27 became IEC 60027. IEC standards often have multiple sub-part documents; only the main title for the standard is listed here. IEC 60027 Letter symbols to be used in electrical ...
The standard provides with the document kind classification code (DCC) a structured letter-code for the classification of any kind of document. A public access database IEC 61355 DB [ 3 ] is available in order to facilitate the individuation of the correct code to be applied to a document
Degrees of protection against electromagnetic disturbances provided by enclosures (EM code) EN 61000-6-1 Electromagnetic compatibility (EMC). Generic standards. Immunity for residential, commercial and light-industrial environments; EN 61000-6-2 Electromagnetic compatibility (EMC). Generic standards. Immunity for industrial environments
The International Classification for Standards has 99 top-level divisions of which only 40 are presently used. The remaining 59 divisions are reserved for topics that are not yet known. There are three "official" levels in the ICS system, each holding ninety nine (99), nine hundred and ninety nine (999) and ninety nine (99) subsets, respectively.
SOH is the ASCII "start of header" code, with binary value 0x01. DDD is the ordinal date (day of year), from 1 to 366. HH, MM and SS are the time of the start bit. The code is terminated by a CR+LF pair. At the end of the timecode, the serial line is idle until the start of the next code. There is no idle time between other characters.
