Using ISO-690 / AFNOR Z 44-005 standard in LaTeX

The bib file is independent of the bibliography style you want to use. If you are okay with using biblatex, there is a package biblatex-iso690 that implements the standard.

Here is a small example:

documentclass{article}
usepackage[style=iso-alphabetic]{biblatex}
addbibresource{biblatex-examples.bib}
begin{document}
    cite{sigfridsson}
    
    printbibliography
end{document}
