You'll need to me more specific. Some standards are initially set by
relevant trade or trade related organisations and may later be more
widely adopted.
ISO or IEC is your best first bet though. Even the US is adopting
International Standards these days.

FEMA, whatever that is, is not a National Standards Body like BSI or
Din, and certainly not a regional or international one like CEN or ISO.
UL is now just another testing lab. The former "UL" standards have

No, FEMA has been around for ages. They help out after big disasters:

TUV said that they wanted X mm clearance on some tracks, no prob,but it
was a very tight layout. I had a really enjoyable time doing it. Then
they said what if they make the boards wrong, ie too small, by 10%, in
the photo process, so can you increase the clearance by 10%.
But I said if the board was 10% smaller it wouldnt fit on the mounting
holes and most of the components wouldnt fit, and we would reject them.
Nope they said....
Well, they should not have. They are not supposed to assume that
anything that is documented will not be AS documented. (But the extent
to which they can pile up worst-worst-worst... combinations of
*permitted* variations has never been tested, AFAIK.) So unless your PCB
drawings had no tolerances on dimensions (or tolerances over 10%) they
were out-of-order.
Something i never considered is:
