Does anybody remember back in the early 2000's when ISO attempted a passive-aggressive coup on the TIA/ANSI standard for Category Ethernet cabling? For Years the TIA ( Telecommunications Industry Association) was evolving "Category Cable" standards, then one day the ISO declared a new category cable with a sequential number bump of the previous TIA standard, which was cat-6. ISO called their so-called new standard Cat-7. I write so-called because there was already preliminary draft work on the same technology by members of the incumbent standards body (TIA). Pretty much ISO modified the TIA's existing draft with a certain member company's ideological opinion on new cable connectors, and rushed it out.
I won't say which ISO member company was pushing hard for their concept of Cat-7, but it was a large European technology company in-and-around Germany, and they had an idea to introduce new cable connectors for which they owned the patent. The new connectors improved interference, and thus improved bandwidth, etc... but were not the backwards compatible traditional RJ-45 style connector the Americans in the TIA were keen to preserve.
This was the most down-played and suppressed drama of all time. Both parties played it very diplomatically, and made absolutely zero public fuss about the issue of ISO attempting to assert itself into another standards body's domain. You may have noticed one or two belligerent nerds on IRC chatting pedantically about this topic every few years. Mostly one clueful nerd saying there is no such thing as Category-7 cable, as if to say that if the TIA doesn't make the standard for cable, it doesn't exist, etc... while another would say that any standards body can make a standard, etc... implying that they didn't care who makes the standard. Regardless, it was well outside the zeitgeist of Networking professionals in the industry, meaning your average network administrators. That is why the ISO thought they could get away with the scandal.
Ultimately the issue was resolved when the TIA established Cat-6a, and then Cat-8, thereby re-establishing their line in the row of category cables. Cat-7 was simultaneously ignored by most-all the members of the TIA member companies, and not certified by many vendors for interoperability. That said, Cat-7 was interoperable using RJ-45 style connectors. It was a sort of industry wide scarlet-letter, the TIA was going to make Cat-7 irrelevant by having the previous standard adopt sub-categories, E.G. cat-6a, cat-6b, etc... And of course reasserting itself sequentially in the versioning scheme they themselves created.
Finally, the ISO was going to do the same thing to networking cables, lock the standard away behind closed doors, but they had misappropriated the technology from an open standard. It's probably unethical, or at least shady. To them it was a new potential revenue stream, and pursing the interests of one of their committee member. All around it stank of collusion, conspiracy, and cronyism.
