ISO 31 isn't always followed strictly. There are many deviations from the various parts of ISO 31 in the scientific and other literature, some of them regional. Example: It recommends "lb" as abbreviation for binary logarithm (log2), and "lg" for 10-logarithm (log10). The author of an American book instead used "lg" for log2. I wrote to him and suggested he followed the standard instead. He replied that he never heard of this standard and thought his notation was better. --Hawklord 21:51, 14 Nov 2004 (UTC)

Besides "surface" as an existing term for "areic", there is also the existing word "areal". —DIV (138.194.12.32 (talk) 09:25, 12 April 2010 (UTC))[reply]

I propose merging all the parts of ISO 31 back into this main article. The articles for those sub-parts are all stubs, as far as I saw, and I think it is very difficult to add much content or sources to improve them beyond that category. Alan Islas (talk) 13:48, 25 June 2020 (UTC)[reply]

The articles on individual parts of ISO 31 should probably be updated and converted into articles on the corresponding parts of the successor standard ISO/IEC 80000, which in many cases are nearly identical. Each individual part of ISO 31 or ISO/IEC 80000 is a quite substantial document containing a large table of quantities and associated conventions, and it would be useful to maintain detailed summaries of these in Wikipedia.
