I had this question popping out while viewing some ISO standards such as ISO 9142.
I searched a little but couldn’t find an explicit ISO standard that is specifically for Computer Icons.
So, has one such standard been published? or a similar recognized one?.
ISO’s technical committee TC 145 is responsible for graphical symbols:
Standardization in the field of graphical symbols as well as of colours and shapes, whenever these elements form part of the message that a symbol is intended to convey, e.g. a safety sign.
You can find a list of related ISO standards and those under their direct responsibility.
If the icons contain text, have a look at W3C’s Web Content Accessibility Guidelines (WCAG), where you can find guidelines how to make the images accessible (contrast).
