I can tell you Toyota follows ISO and it's a big deal there. At least their logistics arm where I worked did. Always kaizen as they say.
They've been doing that for over 20 years. Worked at a tier 1 auto part supplier. They supplied painted parts to all manufacturers, but the Toyota stuff would get scrapped if there was a blemish 1mm big. Everything else was put on the floor, then the QC guy would step back 10' to see if you could still see the blemish. "good to go"
