How to Check the Production Date of Automotive Glass?

[LeEmersyn]

Methods to check the production date of automotive glass: 1. Look for the code at the bottom left or right corner of the window glass; 2. The number represents the year, and the dots represent the month; 3. Dots before the number indicate the first half of the year, while dots after the number indicate the second half of the year; 4. The number of dots represents how many months forward or backward from the midpoint of the year. Classification and functions of automotive glass: 1. Laminated glass: A transparent adhesive plastic film is sandwiched between two or three layers of glass, enhancing the glass's resistance to breakage; 2. Tempered glass: Ordinary glass is quenched to create internal stress, causing it to break into small, blunt-edged fragments upon impact, reducing the risk of injury to passengers.
