Choosing at random I found ISO 105 Textiles — Tests for colour fastness It has about 100 sub standards, and per the ISO website each one costs ~50 USD, or $5,000. Just for one aspect of working with textiles. Maybe it's less if your buy the entire ISO 105 block? I didn't see it listed. Either way, it seems very expensive to be ISO compliant.
