A stands for a non-slip value for dry floors, such as a dry dressing room floor.
Slopes > 12°

B indicates that the anti-slip rating is high enough for wet floors, such as showers in commercial areas.
Slopes > 18°

C stands for damp or soaking wet floors in, for example, swimming pools, such as walk-through foot baths or stairs in the water.
