Ratings come from 30 × 30 mm samples cast at each product's prescribed thickness, cured for 7 days and fully submerged at 20–25°C. On a real floor, a spill only touches the surface, so performance is usually better. Elevated temperatures accelerate chemical attack. How to read these ratings.

Is epoxy flooring resistant to acetic acid?
ASP's epoxy products are not rated excellent for acetic acid at the tested conditions. Check the table for shorter-term ratings, or consider the polyurethane or vinyl ester ranges.
Is polyurethane flooring resistant to acetic acid?
Some ASP polyurethane systems are rated excellent for acetic acid at 5% at 20°C, 10% at 20°C or 20% at 20°C.
