Authentication Methods and Classification Standards for Explosion-Proof Cell Phones
How to check the authenticity of explosion-proof cell phones?
Recently, many people have raised questions like "There are so many fake and shoddy products now, what if I buy a fake explosion-proof cell phone?" Indeed, there are many fake and shoddy products now, and they are all made to look very real.
Method to check the authenticity of explosion-proof cell phones: We can go to the website of the Security Mark Testing and Research Institute. It is a specialized organization for querying the authenticity of explosion-proof cell phones and testing whether they are qualified or not. Just enter the name of our company in the enterprise name column, click on the search button, and the explosion-proof information of the phone will appear. Click on the product you want to query, and you will be able to see the information of this explosion-proof cell phone.
For example, let's take X11 explosion-proof cell phonewhich is a Huawei-made phone that has been modified to become an explosion-proof cell phone branded as "Sichuan Xuxin". You can check our company's explosion-proof information on the website of the Security Mark Testing and Research Institute. You will see all of our company's products there.

Classification standards for explosion-proof cell phones
The classification standards for explosion-proof cell phones are very strict. In fact, not only explosion-proof cell phones have classification standards, other flameproof mobile phone also have them. Explosion-proof cell phones are generally used in coal mines and chemical industries. There is only one strict requirement for coal mines with underground mine phones. For chemical industries, explosion-proof cell phones need to pass IIC and IIB explosion-proof qualifications.
Explosion-proof cell phones should be used in Zone 1 and Zone 2 hazardous environments of the chemical industry, and can be used in hazardous goods production, logistics and warehousing in industries such as petroleum, chemical plants, natural gas extraction, and pharmaceuticals. It can also be used as a professional handheld terminal to enter explosion-proof areas such as chemical plants and inspection areas for work operations.

Classification of explosive zones
It is a measure of the actual possibility of danger in the area, and determines the applicable type of explosion-proof device. The following is the classification of hazardous area levels according to the Electrical Committee/European Electrical Committee: Zone 0: environment where explosive gas mixtures continuously or for long periods appear; Zone 1: environment where explosive gas mixtures may occur during normal operation; Zone 2: environment where explosive gas mixtures cannot occur during normal operation or even if they do, will only exist for a short time.
