How to Check the Production Date of Vehicle Glass?

[DiHector]

The method to check the production date of vehicle glass is: 1. Look at 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. Dots in front of the number indicate the first half of the year, and the month can be calculated by subtracting the number of dots from 7. Dots behind the number indicate the second half of the year, and the month can be calculated by subtracting the number of dots from 13. Classification and functions of automotive glass: 1. Laminated glass: A transparent adhesive plastic film is applied between two or three layers of glass, enhancing the glass's resistance to breakage; 2. Tempered glass: Ordinary glass is quenched to form certain internal stresses. When impacted and broken, the glass splits into small fragments with blunt edges, reducing the risk of injury to passengers.
