Defects Area Scratches/ scattered defects Tolerances Front Scratches that are visible and assessed at a distance of 1 metre are not allowed and considered to justify complaints. Scattered defects <=0.2mm are allowed and not considered to justify complaints. Scratches that are visible and assessed at a distance of 1 metre are not allowed and considered to justify complaints. Scattered defects <= 0.5mm are allowed provided that scattered defects do not occur closer than 200mm to each other.
