Cite Them Right treats the standards body as the author and puts the standard’s number and title together, in italics, after the year.
For a standard read online, add Available at: with the URL and the access date in round brackets.
You may name the standard by its number in your sentence, with the body and year in the citation.
A British adoption such as BS ISO 690:2021 is published by the British Standards Institution, which then becomes the author.

Evidence and review notes

Worked examples on this page are written by hand from the style's own published guidance and checked against it, because the general CSL styles do not encode this source's rules. Editorial guidance and sources in this section were reviewed on 2026-08-14.

Metadata to collect

the standards body as author
the full designation with its year, such as ISO 690:2021
the exact title as printed, including its dash
the edition number and publication date
the URL or database you used
the clause or section you cite

Common metadata traps

A designation without its year, such as ISO 690, points to whichever edition is current, so always give the year of the edition you read.
The page at iso.org is a catalogue record and preview, not the full text; if you read the standard through a library database such as a national standards body’s platform, cite that copy.
National adoptions such as BS ISO 690:2021 are published by the national body, so cite the version actually in front of you rather than the ISO original.
