I don't have Renault Standard off-hand. But your question reminds me of the days when my Supplier was trying hard to meet the required visual charateristics on Cast surface (can you imagine on cast surface). I was representing Renault Supplier Quality then and I remember we even measured Glossiness, paint thickness, etc on cast surface. We later switched over to electrostatic painting process and resolved the issue.
By the way, what acceptance criteria is the drawing referring to?
