Requesting historical documents

If any one has links to old historical standards for component values prior to 1952, please post a link or expand the history section. Thanks in advance. • Sbmeirow • Talk • 09:34, 11 July 2017 (UTC)[reply]

I have commented out the "E1" series (if it ever existed), since I could not find any historical sources for it (and I never heard of it before).

Article renaming

Please quit renaming the article. Discuss it the talk section, settle on something, then change it. • Sbmeirow • Talk • 03:37, 25 July 2018 (UTC)[reply]

OK, yes, that would have been better. But I took the discussion instead to User talk:Matthiaspaul#E series where we worked it out. If you disagree, let us know. Dicklyon (talk) 05:28, 25 July 2018 (UTC)[reply]

Rounding Rules

The article is mentioning that E24 and below are using different rounding rules than E48 and above. But there are no references, links or other hint to what these rules are or where they are defined. This is problematic, for people trying to implement this algorithmically without having to resort to lookup tables. Please add rounding references if you know it.
