| 1. Appearance |
1) Air bubble: Diameter≤0.5mm,in the *0mm x *0mm 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 *0mm. The air bubble of Diameter from 1.5mm to 2mm ≤3 on the No-sight plane. Their distance must *0mm. 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 depth 1mm. 5) Crack: dont allow have crack. 6) Scrape: On the sight plane and in the 7.5mm to edge,the scrape of less than *0mm dont allow more 2 strips. 7) The sight plane must be polishing,and sealing side must be rubbing and polishing. |
