Negligible Minor Major Point defects Bubble: Air pocket, sometimes coloured entrapped in glass d ≤ 0,8 mm 0,8 mm < d ≤ 2 mm d > 2 mm Impurities: Small impurity in glass or interlayer, or an embedded particle d ≤ 0,8 mm 0,8 mm < d ≤ 2 mm d > 2 mm Spot: Local translucent area on interlayer d ≤ 0,8 mm 0,8 mm < d ≤ 2 mm d > 2 mm Surface defect: Blemish caused by minor impact or abrasion (e.g. between two sheets of material during storage) d ≤ 0,8 mm 0,8 mm < d ≤ 2 mm d > 2 mm Anti-spall layer specific defects Skin blister: Localised deformation of the transparent surface d ≤ 1,5 mm 1,5 mm < d ≤ 3 mm d > 3 mm Cord: A relatively thick and very obvious thread of material L ≤ 5 mm 5 mm < L ≤ 10 mm L > 10 mm Coating drip: Uneven thickness of final coating d ≤ 5 mm 5 mm < d ≤ 10 mm d > 10 mm Linear defects: Defects where the length to width ratio is high. The dimension given is the direct distance between the extremities of the defect. Scratch, chipped scratch: Superficial scratch, rectilinear or curvilinear, with shelling to each side of the scratch − All dimensions Fine scratch or other linear defect detectable by touch d ≤ 13 mm 13 mm < d ≤ 40 mm d > 40 mm Hairline scratches hardly detectable by touch but visible on the surface All dimensions − Print of attenuated (repaired) scratch d ≤ 13 mm 13 mm < d ≤ 40 mm d > 40 mm Lint, fibre, hair: Elongated impurity entrapped between glass ply and interlayer when laminating d ≤ 13 mm 13 mm < d ≤ 40 mm d > 40 mm Streak, mark (drag) trace:
Whitish area in the interlayer, hardly detectable under daylight condition Any dimension, but one that does not attract the eye at 3 m from the product If attracting the eye at 3 m from the product and having total surface ≤ 8 cm²If attracting the eye at 3 m from the product and having total surface > 8 cm²

Negligible Minor Major Edge defects: These defects shall never extend beyond the peripheral area. Tong marks: Impressions made in glass by the tips of the tongs used to suspend the glass during tempering which induce a local deformation, iridescence and hairline scratches Disregarded
Bending tool mark: Impressions made in glass in the peripheral area by the bending tool Disregarded
Shell, chips: Small loss of glass fragment, at the edge, not totally eliminated by grinding. However, sharp edges that may cause injury when fitting the windscreen shall not be accepted. The grinding to eliminate these defects can extend up to 10 mm from the edge of the glass d ≤ 1mm 1 mm < d ≤ 2mm d > 2mm Silk-screen printing special defects Impurities under silk screen: d ≤ 1,5 mm 1,5 mm < d ≤ 3 mm d > 3 mm Dot fade-out: Visual inspection shall confirm that the uniformity of the dot fade-out pattern is acceptable and any irregularity does not attract the eye at 3 m from the product

Vision area Negligible Minor Major Area A Disregarded See a A maximum of 3 defects of any type within any circular area of d = 300 mm 0 Area B Disregarded See a A maximum of 3 defects within any circular area of d = 100 mm 0 Area C See b See b See b Printed Area See c A maximum of 3 defects inside any region of length 100 mm 0 a The accumulation of these disregarded defects shall not impair useful vision. b Appearance defects shall only be tolerated provided they do not impair the mechanical properties of the windscreen. The following defects are allowed in Area C only:  irregularity in external dimension of individual layers (maximum 5 mm/edge);  bubbling;  delamination;  opacity of the interlayer with a total surface area of these defects to be less than 2 % of the peripheral zone surface. c In areas used for bonding of glued windscreens the accumulation of disregarded defects shall not permit average Ultra Violet transmittance of more than 0,1 % when a glue protection is specified.
4.3.2 Heating system 4.3.2.1 General If an integral heating system is specified by the customer, it can be provided by an electric system using:  coating;  wires embedded in the windscreen. At the minimum such a heating system shall be effective across the primary vision area of the windscreen.

4.3.2.3 Defect acceptance criteria of wires Irregularities due to defective electrical continuity shall not exceed:  maximum two non-heated zones ≤ 15 mm wide, at least 45 mm apart or a single non-heated zone ≤ 20 mm wide;  non heated or over heated zone ≤ 5 mm wide; The accumulation of permitted defects shall not impair the optical properties or prevent useful vision.
