1) Air bubble:

Diameter≤0.5mm, in the 10mm x 10mm area the quantity must be ≤3.Diameter from 0.5mm to 1.5mm dispersive air bubble, there is less 2 on the sight plane and less 5 on the No-sight plane. Their distance must be 40mm.

The air bubble of Diameter from 1.5mm to 2mm ≤3 on the No-sight plane. Their distance must 40mm.

On the sight plane, The distance to the side in 7.5mm,the air bubble of the diameter1mm mustnt be more 2.

2) The glass dont allow slag and scrap iron, etc. impurity.

3) Stripe: dont allow have palpable filaceous and pectinate stripe on the sight plane.

4) Cockle: In the side face, dont allow have the cockle of depth1mm.
