If you see cords it'll be a definite fail. If it's a large cut but no cords it should be a fail but borderline. If its a small nick then it'll be down to the testers discretion
If you can see cords, including folding back the rubber in a cut to expose cords, it’s a fail. If you can feel but not see cords in a cut bigger than 25mm, or 10% of the width, it’s a fail.
