The WARC File Format (ISO 28500) - Information, Maintenance, Drafts.
I confirm - as convenor of the WARC format ISO working group - that there are no substantial modifications between the version on http://bibnum.bnf.fr/WARC/index.html and the ISO standard, except some little editorial changes. So it may be used as a trustworthy reference.
As far as I know, ISO organization resources comes largely from the selling of their standards, so it is not possible to make them freely available, except in some cases. The case of ISO/IEC standards is one of these exceptions; it is due to the fact that the standards are developed by two organizations with different publication rules (ISO and IEC).
Even as convenor, I had no free copies of the standard.
I will check again with ISO secretariat but I doubt it will be legal to make freely available the official version.
This is a reason why there is a common practice to publish draft standards
- such as we did on BnF website.
