We all know that the date of production of the glass can be seen on the window glass. In distinguishing whether the vehicle has had an accident (the vehicle has rolled or knocked the glass is very simple damage), it is of great help to replace the window glass. But this date code we may not pay too much attention to, we can take a look at this date code is not a general combination of year month day pattern.

Month year can be analyzed according to the number, then how to look at the month, we can look at some small dots before or after the number, the effect of this small dot is originally used to judge the production month of glass. The small dot in front of the number indicates the first half of the year, and the accounting pattern 7- number of points before the number = month. The small dot behind the number indicates the second half of the year, and the accounting pattern 13- number of points after the number = month, as shown in Figure 13-1=12
Chow told me more about some of the glass, behind the date code will be a few black star-shaped dots, This little black star we read out in the week of a month 5 represents 1-74 8-143 15-212 22-281 28-31 Some years February as long as 28 days will not present a star to learn to distinguish this date is of great help to us, for example, the window glass and the vehicle date difference of more than 1 year can be sure that the glass has been replaced!
