Is It Normal for the Production Dates of New Car Glass to Be Different?

[McAlexander]

It is normal for the production dates of new car glass to be different. Car glass is produced in assembly lines, and different batches of glass may have different production dates. Methods to check the production date of glass include: 1. Look at the code in the lower left or lower right corner of the window glass; 2. The numbers represent the year, and the dots represent the month; 3. If the dots are in front of the numbers, it indicates the first half of the year, and subtracting the number of dots before the numbers from 7 gives the month in the first half of the year; 4. If the dots are behind the numbers, it indicates the second half of the year, and subtracting the number of dots after the numbers from 13 gives the month in the second half of the year. The classification and functions of car glass are: 1. Laminated glass: A transparent adhesive plastic film is placed 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, so when it breaks upon impact, it splits into small, blunt-edged fragments, reducing the risk of injury to passengers.
