International Organization For Standardization - Name and Abbreviation

Name and Abbreviation

The three official languages of the ISO are English, French, and Russian. The organization's logos in two of its official languages, English and French, include the word ISO, and it is usually referred to by this short-form name. The organization says that ISO is not an acronym or initialism for the organization's full name in either official language; rather, recognizing that its initials would be different in different languages, it adopted ISO, based on the Greek word isos (ἴσος, meaning equal), as the universal short form of its name. However, one of the founding delegates, Willy Kuert, recollected the original naming question with the comment: "I recently read that the name ISO was chosen because 'iso' is a Greek term meaning 'equal'. There was no mention of that in London!"
