{{Short description|ISO standard}}
'''ISO 843''' is a system for the transliteration and/or transcription of Greek characters into Latin characters.<ref>[http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=5215 ISO 843:1997], International Organization for Standardization</ref>

It was released by the [[Organization:International Organization for Standardization|International Organization for Standardization]] in 1997. The transcription table is based on the first edition (1982) of the ELOT 743 transcription and transliteration system created by ELOT and officially adopted by the Greek government. The transliteration table provided major changes to the original one by ELOT, which in turn aligned to ISO 843 for the second edition of its ELOT 743 (2001).
