Level Gauge Glass Physical Property
Testing Item	Standard Rules
1. Appearance	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 diameter2) The glass don't allow slag and scrap iron,etc. impurity. 3) Stripe : don't allow have palpable filaceous and pectinate stripe on the sight plane. 4) Cockle: In the side face,don't allow have the cockle of depth >1mm. 6) Scrape: On the sight plane and in the 7.5mm to edge,the scrape of less than 10mm don't allow more 2 strips. 7) The sight plane must be polishing,and sealing side must be rubbing and polishing.
2. Colour and Lustre	It should be no color and transparent,and with its self tine green is allowed.
3. Water-resistance	Cooked in the water for 5 hours,then weigh up ,then titration with 25ml 0~31 ug/g
