China (Mainland) Automotive Glass

Specifications: Mechanical performances: Impact resistance: Use a 227g weight steel-ball falling free from 2 meters height to impact the test-sample, the steel-ball couldn\'\'t penetrate the test-sample. The total weight of fragments on the reverse side is no more than 20g.

Penetration resistance: Use a 2260g steel-ball falling free from 4 meters height to impact the sample, the ball couldn\'\'t penetrate the sample. Impact by head-like model: Use a head-like model falling free from 4 meters height to impact the sample, the head-like model couldn\'\'t penetrate the sample; moreover, there\'\'s no large piece of fragments drop.

Optical performances: Transmittance75% Second image migration: The maximum migration between the first and the second image: A or a zone is 15\'\', b or b zone is 25\'\'. Light distortion: The maximum light distortion is a or a to be 2\'\', b or b to be 6\'\'.

Radiation resistance: After illuminated 100 hours by a special light resource, the transmittance relatively reduced 5%. Heat resistance: After boiling 2 hours, there\'\'s no air bubble or defect appeared on edge which is over 15mm from edge or 10mm from break. Scratch resistance: According to the result of scratch-proof testing. The foggy rate is 2%.

Wet resistance: According to the result of wet-proof testing, nothing obviously changed on the edge which is over 10mm of the sample (such as color changing, bubbles, mist).
