A large collection of reflective material standards

In scenic spots or traffic sections, there are usually some signs to remind us to pay attention to certain issues before a crisis strikes. But what materials are used for these signs to be reflective and conspicuous? So today the editor will tell you about this kind of material that often reminds us, reflective material. It is widely used in many places in life, such as safety facilities, reflective signs, vehicle numbers, etc. So next, the editor will tell you about this kind of reflective material and its due standards.

Reflective materials are mainly used for the production of various reflective signs, vehicle license plates, safety facilities, etc. Their bright colors play an obvious warning role during the day and at night or when there is insufficient light. , its bright reflective effect can effectively enhance people's recognition ability, see targets clearly, and arouse alertness, thereby avoiding accidents, reducing casualties, and reducing economic losses. It has become an indispensable safety guard for road traffic and has obvious social benefits. . The scope of use widely involves public security transportation, traffic supervision, fire protection, railways, coal mines and other departments. Civilian reflective materials are mainly reflective cloth, reflective lattice sheets, reflective inkjet cloth, etc. The reflective material adopts the principle of microprism reflection. Everyone knows that light reflection includes diffuse reflection and specular reflection.

Why can retro-reflective materials return light along its original path? In fact, this is mainly due to the high-refractive index glass beads contained in it. When a beam of light irradiates the front surface of the microbeads at any angle within a certain range, due to the high refraction of the microbeads, the light is concentrated on the reflective layer on the back surface of the microbeads. The reflective layer reflects the light back in parallel along the direction of the incident light. . A retroreflection is formed. When many glass beads reflect simultaneously, the bright scene ahead appears. Drivers driving at night are easily affected by the lights of oncoming vehicles, roadside lights, high-rise searchlights and advertising neon lights, which can easily cause traffic accidents. The bright light emitted by reflective material signs under the illumination of car lights is particularly eye-catching, which can remind drivers to pay attention to relevant road condition information and improve driving safety. In weather with low visibility such as rain, fog, wind and sand, reflective materials can highlight their value even more. Therefore, many developed countries stipulate that reflective materials must be used on road and railway traffic signs, front and rear of the vehicle body, and the International Marine Lifesaving Agency also stipulates that lifesaving equipment must be equipped with reflective materials to facilitate night search and lifesaving work.

Reflective material standards need to be tested, but the tests are also differentiated. Reflective materials used for transportation must be tested by the Ministry of Transportation of the importing country. The requirements for such products are very strict. Reflective materials used in children's toy products are generally tested according to EN13356. EN471 is the European standard for high-visibility clothing product specifications. This standard specifies the performance of protective clothing, and this performance demonstrates that the wearer's presence can be displayed whether it is illuminated by headlights during the day or at night. These requirements include the area of ??use of the material, color and retroreflective materials.

Reflective standards can also refer to: GB5768 "Road Traffic Sign Standard", GB18833 "Road Traffic Sign Reflective Material Standard", GA406 "Vehicle Reflective Marking".

After listening to the content brought to you by the editor and the above explanation, do you have some understanding of some signs, numbers and facilities related to reflective materials around us? ? I believe that everyone will pay more attention to the wide application of this reflective material in the future. After understanding this material, we will definitely feel that this kind of thing is also very important to us. It is the slogans made from this material that effectively warn and remind us. Therefore, everyone must spread the knowledge of reflective materials to those around them!
