How to Determine the Production Date of New Car Glass?

[VonAlice]

Confirming the production date of new car glass can be done by: 1. Checking the code at the lower left or lower right corner of the window glass; 2. The number represents the year, and the dots represent the month; 3. If the dots are in front of the number, it indicates the first half of the year, and subtracting the number of dots before the number from 7 gives the month in the first half; 4. If the dots are behind the number, it indicates the second half of the year, and subtracting the number of dots after the number from 13 gives the month in the second half. The classification and functions of car glass are: 1. Laminated glass: Transparent adhesive plastic film is applied between two or three layers of glass, increasing the glass's resistance to breakage; 2. Tempered glass: Ordinary glass is quenched to form certain internal stresses, and when impacted and broken, the glass splits into small fragments with blunt edges, reducing the risk of injury to passengers.
