Contents

The document, unit by unit

23 units are recorded: 15 clause pages and 7 annex pages, including one page for each of the five Annex A examples. 9 units are read in full from the ISO public preview. 14 are titled in the published contents list with the body not in the public preview; those pages say so and state no requirement.

The base standard is 18 pages. Our ISO public preview is 11 of them and stops at clause 6.3. We do not describe a clause we cannot read, and we do not reproduce a test vector we do not have. The amendment has no public body, so it has no clause pages; its record is on the publication page.
