Plugs are electrical accessories often used in our daily life, mainly used to connect the power supply and electrical equipment.However, in the process of purchase and use we need to pay attention to whether the plug is in line with national standards. Because only in line with national standards to ensure the safety, durability and reliability of the plug can be used.

First, check the logo of the plug

In the purchase of plugs, the first thing to check the plug above the logo, whether it is in line with national standards. The national standard plug mark is "CCC". If you can't find this mark, then you need to be careful. Because it may mean that the plug did not go through formal testing, or the quality does not meet the national standards.

Second, check the structure and material of the plug

The national standard plug should have a specific structure and material, which is to ensure the durability, reliability and safety of the plug. Usually, the plugs stipulated by national standards are made of compression-resistant and flame-retardant materials, and the head of the plugs should have an anti-electrocution arrangement to prevent the electrical recoil current from electrocuting the human body. In addition, the plug interface should be as large as possible, so as to facilitate the plug and socket insertion operation, and the plug and socket contact surface should be coordinated and smooth, in order to avoid insertion loosening and easy to slip and other issues.

Third, check the performance indicators of the plug

In addition to the appearance and material, we also need to look at some important performance indicators, such as voltage, current, power and so on. Generally speaking, the voltage standard of the plug should be 220V/50Hz, and the current standard needs to be selected according to the specific situation and the power of the appliance, if the power of the appliance is less than or equal to 1200W, it is necessary to select the current standard below 10A; if the power of the appliance is greater than 1200W, it is necessary to select the current standard of 16A. In addition, you also need to pay attention to whether the plug has over-current protection and over-voltage protection and other functions.

Fourth, through the certification body query

Finally, if you have any questions when choosing the plug or need to confirm whether it is in line with the provisions of the national standard, you can query through the certification body. At present, some authoritative certification bodies in China are food and drug testing organizations, electrical safety testing organizations, certification companies, etc. These organizations can provide you with professional services. You can check through their official website, telephone or field to their testing organizations to ensure that the plugs you buy meet the national standards.

In conclusion, it is very important to choose plugs that meet the national standard regulations in our daily life. Because it can not only protect our safety and using experience, but also avoid some unnecessary accidents. Therefore, when using plugs, please make sure to pay attention to the above points and choose plugs that meet the standards.
