Hidden information on the car window

Information hidden on the car window:

Generally speaking, the logos on domestic auto glass can be divided into four categories: national safety certification mark, foreign certification mark, automobile production factory mark, and glass production enterprise mark. Safety glass for automobiles is a national compulsory certification product, so every glass on the car should have a national safety certification mark, also known as the "square mark", which is the most common and most important symbol on the automobile glass. Others include foreign certification marks, such as the US "DOT" logo, the European ECE "E" logo, etc., indicating that the product has also been certified by these foreign certification bodies and can be exported abroad.

In order to avoid boring, we do not do professional explanations, just introduce, I believe that after reading a few examples of this article, you can have a general understanding of your car glass, at least in the future when you choose a new car or even replace the glass. in vain.

This is a Fox rear windshield with a set of trademark codes in the lower right corner, which is mandated by national regulations. All automotive glass is required. They are usually placed on the lower left or lower right corner of the glass. Among them: FORD means... OEM products specially produced for Ford

(DMLQA) DOT814... Factory code certified by the US Department of Transportation

E000666...European ECE (EconomicCommissionforEurope) certification code

CCC... China 3C compulsory certification mark

M532AS2... US Department of Transportation DOT certification code and glass classification code

TEMPSAFETYGLASS...Safety glass type (isolated)

".8"...8 indicates the year, which is 2008. The black point is before "8", indicating the production in the first half of the year. The calculation formula is "7-black dots". For example, the car glass in the drawing is .8, it should be It is 7-1=6, so this glass should be produced in June 2008; if the black point is after “8”, it means production in the second half of the year, and the calculation formula is “13-black dots”, such as “8. ", said that the car glass is 13-2 = 11, which was produced in November.

â–²TINTEDâ–²... indicates upward mounting, tinted glass.

Let's take a deeper exploration:

This piece is Fox's front windshield. The big Ford logo tells us that Fox's front windshield is from a manufacturer specializing in Ford's accessories, and the code of "E000666" not only indicates that it has obtained 3C compulsory certification, but further to us. Explain that the origin of this glass is Fuyao Glass (Chongqing) Co., Ltd. Finally "LAMISAFETYGLASS" where lami is a shorthand for lamination, meaning "sandwich safety glass", which breaks into small pieces of honeycomb when broken, generally no more than one centimeter in diameter, and has a certain degree of adhesion. That is to say, it is not easy to fall off and hurt people when it is broken. Now almost all of the front windshield is laminated glass.

Everyone noticed that there is an "AS1" sign on the front windshield of this car (Fig. 1), and the rear windshield is "AS2" (Fig. 2) in the corresponding position. What does this mean? This is the American standard "Sootvetstvie". Shorthand, secondly, it can also indicate some information, "AS1" stands for the transmittance of this glass is not less than 70%, that is, "clear glass" can be used for the front windshield, and "AS2" represents the light transmission rate. Not less than 70% glass, but its usable range is "can be used anywhere except the front windshield".

“FY” stands for Fuyao Auto Glass

Mazda's window information is relatively simple. In addition to the logos of FAW and Mazda and the 3C compulsory certification mark in China, we can also analyze the following information: “FY” indicates that the manufacturer of the glass is domestic Fuyao Auto Glass Factory. The factory belongs to the domestic first-line auto glass fittings factory. Nowadays, many of the domestically produced cars are Fuyao brand auto glass. The quality has been tested by the market, and the riders can rest assured.

Secondly, "E000137" represents Fuyao Group Changchun Co., Ltd. Fuyao Auto Glass has many production plants in China (headquartered in Fujian), so we can know the specific origin of this glass through this code. “E000137” shows that this glass is produced by Changchun. The bottom "LAMINATED" tells us that this is a laminated glass. Finally, according to the calculation method ".....0" introduced earlier, this glass was produced in February 2010.

The door side window glass, rear windshield, and skylight (in order) have the same basic information as the front windshield, but we can additionally notice that the production date of the FAW Mazda Ruiyi window is highly uniform, and the date is close to the time of the card. We can also infer that the car is relatively smooth in its production process, without inventory, the car accessories are the same batch of products.

The shelf life of automotive glass is generally very long, so the more practical effect of this method is to help you roughly determine the assembly time of the car through the production time of spare parts on the car, if the date of manufacture on the car glass and the date on the nameplate are very large. The time gap indicates that the car may be an inventory parts assembly vehicle. This situation mostly occurs on models that have been on the market for many years. In addition, when you pick a used car, you can also use this method to determine whether the car has had an accident, replaced the glass.

Shanghai GM Buick New Regal:

The information on the new Regal window is quite rich, among which “LAMINATED” tells us that this is a laminated glass. The two codes “DOT747 and E000090” also show us that the origin of this glass is Fuyao Shanghai Co., Ltd. In addition, a new letter code appeared on the glass of the new Regal, "TRANSP.70%MIN" represents the light transmittance, indicating that the minimum light transmittance of this glass is not less than 70%, it is related to "AS1" The same meaning, light transmittance is an important parameter to measure the quality of a piece of glass, but generally it will not be clearly marked, so in the future when the riders need to replace the car glass, it is necessary to ask this as a seller.

This new Regal's sunroof glass production area is different from other windows. "E000001" indicates that this glass comes from Fuyao Glass Industry Group Co., Ltd., and the "E" in the circle is the European automotive glass audit code, with our Little relationship.

Shanghai GM Chevrolet - Cruze:

The window information of Cruze is more complicated, but after finishing it, we can know that the codes of “43R-000058”, “DOT747” and “E000090” have explained to us that the front windshield of Cruze is produced by Fuyao Shanghai Co., Ltd. Laminated glass. And "...9" showed us that its production date is April 2009.

Here we introduce to you, the "M848" located between DOT and AS1 is mainly used to mark some types of glass information, such as color, thickness, etc., and generally a manufacturer can have multiple sets of numbers, so the same manufacturer This is normal for different code.

It is noted that in addition to the front windshield laminated glass, Cruze uses tempered glass (TEMPERED).

On the same Cruze, we found glass from different places of origin. The manufacturer of this skylight is Fuyao Group Changchun Co., Ltd. The E000137 and DOT782 codes clearly show us that this glass is produced in Changchun instead of Shanghai. . It is normal for such a “mix and match” to occur. On the one hand, due to the high demand for hot-selling models, the capacity of a parts factory is often insufficient to meet the demand; on the other hand, it is even less likely that the car factory will hang on a tree. "Maintaining business with several parts factories is a must for business." Therefore, netizens do not have to have any negative emotions about "mashups." For example, this skylight glass from Changchun is a tempered glass with heat insulation. Even if it is not closed, it will not hurt your scalp.

The tempered glass sold in the general market cannot be used for the front windshield because of safety problems. This requires everyone to bear in mind.
