Modern vehicle is enoughIt's hard to imagine without darkened glasses. However, the light transmittance of toning must meet regulatory requirements. It is determined using special devices by traffic police officers. With proper work to apply a protective layer of problems with the law does not arise.
Why tint car?
Before you talk about light transmissiontinting, you need to decide whether it is needed in each case. To do this, it is enough to study the main advantages that blackout automotive glass provides. There are a lot of them:
- high decorative possibilities;
- protection of interior elements from burnout;
- protection of the driver against glare by ultraviolet rays;
- confidentiality of personal space;
- overheating exception.
As an added benefit, you canNote another advantage that is achieved when using durable films. This is an increase in safety in case of an accident. Some types of materials used to hold particles of broken glass.
What factors can deter?
Despite these advantages, car tinting has a number of significant drawbacks. They are listed below:
- some reduction in visibility;
- the possibility of applying penalties for non-compliance with certain requirements;
- the likelihood of defects on the glass with an incorrect blackout.
Многих потребителей эти минусы не пугают.Therefore, the application of protective layers against ultraviolet continues to be popular. Disadvantages can be leveled by using quality materials and a clear study of basic requirements.
Basic standards of light transmission
When the tint ban was lifted,motorists began to actively darken the glass. However, they often do not take into account the indicators of light transmission, which leads to the application of penalties. When applying protective coatings from ultraviolet radiation, it is necessary to focus on the GOST points.
Государственные стандарты допускают к управлению vehicles, light transmission tinting which is 70 percent for the windshield. Front also allowed to apply shading strip width less than 140 mm. They are placed strictly at the top. As for the front side windows, they should also skip at least 70% of the light. This is necessary so that the driver can clearly see from the sides and front. There are no requirements for dimming to other glasses, if the rear-view mirrors are installed on the sides.
Представленные параметры не должны применяться directly to the purchased film or sprayed layer. It is also necessary to take into account the light transmittance of the glass itself, since this indicator is not 100%.
Thus, although the ban ontinted, there are certain restrictions on the dimming of glass, which are located on the side and in front of the driver Therefore, when coating should be a weighted approach. Otherwise, you can get into an unpleasant situation with law enforcement officers.
Methods of applying a protective coating
Чаще всего тонировка авто производится с using specialized films. The simplicity of this method allows motorists to carry out work without contacting the workshops. If necessary, such a coating can be removed from the glass surface, which is relevant when claims are submitted by traffic police inspectors. There are many types of films that differ not only in aesthetic but also practical characteristics.
Another option to darken the glass is toapplying a special coating in the factory. It is resistant to mechanical stress. To obtain a quality layer, you need expensive equipment. In domestic conditions, to achieve an acceptable result is problematic.
In some cases, tinted side windowscarried out by means of removable panels that are coated. If desired, they can be dismantled as quickly as possible. Dimming the cabin with these elements is relatively cheap.
By innovative types of electronicvehicle tinting. Electrochemical composition is applied to the surface of the glass. Transparency with this option varies depending on the ambient light. Any problems with driving a car in the dark are simply absent.
Devices for testing light transmission
Auxiliary device for interestdetermine the penetration of sunlight is taumeter. With it, traffic police inspectors measure the degree of light transmission. Widespread devices that are reflected in the table.
Name | Conditions | Description |
"Blik-N" | Measurements are made at temperatures from -10 to 40 degrees. The glass thickness should be 3-10 mm, and the relative humidity of the air - no more than 95% | It is the most popular among other analogues. Differs in the compact sizes. The mass of the device is 900 g |
"Tonic" | It can be used for glasses up to 2 cm thick. It is recommended to be used in the temperature range from -10 to 40 degrees | It is a portable device. Functions from a small power 3.6 volts. The weight of the product is only 500 g. |
"Shine" | The width of the tested samples should vary within 3-6 mm. Measurements can be carried out at any time of day at a temperature of from -40 to 40 degrees | Not very easy to use, as it weighs 1.4 kg. In this regard, traffic police officers use relatively rarely. It is a stationary continuous device. |
The listed devices allow you to successfullydetermine the allowed percentage of tinting on the front windows. The level of darkening behind, as mentioned above, is not checked by inspectors. However, the error of these models can still vary from 2–4 percent.
Features of the measurement
Taumeter, like any other measuring devicetype must be certified without fail. Such events are usually held annually. After the verification is completed, a certificate is issued to the device if it meets all the requirements.
The mechanism of work is as follows.
- First, the test sample is illuminated by the emitter.
- Further, a certain proportion of the luminous flux goes directly to the receiver.
- Then the captured radiation is transformed into a digital signal and displayed on the display.
In order to provide reliable technical equipment, special requirements are imposed on its use. They are as follows:
- A prerequisite is the presence of a seal on the device;
- the label should indicate the date of the next inspection;
- measurements should be made three times in different places, calculating the average;
- the test specimen must be cleaned of contamination before taking readings.
Road test conditions
Use the device for measuring tinting caninspector or employee of technical supervision of traffic police. Checking should be done at fixed stations or checkpoints. Although at a stop outside the post, traffic police officers may offer to undergo testing with a special device, in fact there is a chance to refuse it.
To force to go to stationary point of carryingtraffic police inspector service can only if the act of detention. However, this requires very serious reasons, which will be detected without identifying a specific violation. And to determine the light transmittance of tinting on the eye is impossible.
About the choice of film coating
Since the option of sticking film usesin great demand, it is worth staying in more detail. First of all, you need to choose the right coverage for your car. Painted films are very popular. They do not appear glare, moreover, they are able to reflect up to 20 percent of thermal radiation. The main disadvantage is the relatively fast bleaching.
More resistant to UV lightmetallized films. The protective layer in this case is located between the main layers or on the inside. The level of reflection of thermal radiation can reach 70 percent. In sunny weather, such coatings acquire metallic luster.
When choosing colors are usually guidedaesthetic preferences. There are a large number of shades. However, the acquired coating should not distort the perception of green and red colors.
Independent application of tint film
Having learned what percentage of toning on GOST is permissiblein the Russian Federation, and also having familiarized with recommendations about the choice of the main material, it is possible to start directly carrying out works. The film will be applied to the glass with a set of certain tools and auxiliary equipment.
It is advisable to cook:
- paper napkins:
- sprinkler;
- blade or stationery knife;
- rubber spatula;
- detergent.
First of all, the glass is thoroughly washed.subject to tint. Even small grains of sand that fall under the coating cause serious defects. A foam solution is applied to a clean surface using a sprinkler. From the blank, cut from a large piece of film, a protective layer is removed. Fitted to the size of the piece is superimposed on the glass.
Air bubbles are smoothed byrubber spatula. After uniform distribution of the coating is carried out drying. For these purposes, use a regular hair dryer. Glass with glued film is not recommended to lower or lift within 72 hours.
Optimal light transmission options for rear windows
The most popular toning is 35 percent.Such films are glued only on the surface of the rear windows. They allow you to effectively protect the interior from the negative effects of sunlight, while visibility deteriorates not so much. They are most often used for cars of light colors.
Another option - toning 15 percent.In this case, the focus is on increasing the degree of darkening. Despite the relatively low light transmission, visibility remains acceptable. This toning is ideal for vehicles of dark colors.
Final part
State standard for determining the levelthe light transmission of the applied films and sprayed coatings must be observed in order to ensure road safety. This applies primarily to the front windows, through which opens the main overview for the driver of the vehicle. The darkening layer blocks visibility while driving. However, this level depends on the throughput of purchased materials.
