Edge cut defects		Defects on the cut edge such as: chips, indentations, protrusions, spiral cracks, chipped corners or protruding corners, deviation from the cut line when viewed perpendicular to the glass surface, must not be larger than the nominal thickness of the glass pane and not larger than 10 mm.
6.	Bow, %, not exceeding		0,30
7.	Optical distortion (angle of distortion), degrees, not less than
	– 2 mm; 2.5 mm thickness		40
	– 3 mm thickness		45
	– ≥ 4 mm thickness		50
Notes: ⁽¹⁾ Bubbles are defects in the form of air pockets inside. Inclusions are defects in the form of non-air-containing particles; ⁽²⁾ D is the diameter of the bubble or inclusion. The size of bubbles and inclusions is taken as the largest outer dimension value; ⁽³⁾ S is the area of the glass pane in square meters (m²), rounded to the second decimal place; ⁽⁴⁾ The limit on the permissible number of bubbles and inclusions is an integer (after dropping the decimal part) of the product of S and the coefficient; ⁽⁵⁾ Area defects, linear defects, scratches are defects appearing consecutively under or on the surface of the glass pane such as: scars, cracks, scratches, inhomogeneous areas.
