What test items are required to apply for an explosion-proof certification?
Explosion-proof products must undergo relevant tests to meet the requirements of explosion-proof standards in order to obtain an explosion-proof certification.
Different explosion-proof types, catering to equipment used in various explosive environments, require different explosion-proof testing items.
Many customers also want to know what types of tests are required for explosion-proof products? What specific requirements are there for the explosion-proof design of the product?
Next, let's take a look at some common explosion-proof testing items.
For instance, with intrinsically safe products, typical test items include appearance and structure inspection, spark ignition tests, dielectric strength, battery and battery pack testing, temperature rise tests, transient energy tests, etc.
Explosion-proof products primarily undergo tests such as heat and cold resistance, internal ignition without propagation of explosion, shell pressure resistance, IP testing, and temperature rise tests. Different testing items,
Each test item for different modules or components of the product ensures that the product meets the explosion-proof standards and achieves the required explosion-proof performance.
If a company is designing explosion-proof products without understanding the explosion-proof standards requirements,
ZheNuo Testing can provide guidance services for explosion-proof circuit design and explosion-proof structural design.
Including explosion-proof standards, design key points, drawing guidance, and offering agency services for explosion-proof testing and certification.

Do you need to do an explosion-proof design before applying for the explosion-proof 3C certification for the product?
That's a given.
The product undergoes explosion-proof 3C certification, which involves passing the relevant test items of the explosion-proof standards and the process of applying for the explosion-proof 3C certificate.
To ensure the product passes the explosion-proof standard test items, it is definitely necessary to design the product according to the test requirements, which is to say, to implement explosion-proof design.
For explosion-proof requirements, refer to GB/T3836.1 and GB/T3836.2.
The design of the intrinsically safe version should refer to GB/T3836.1 and GB/T3836.4.
The design of the positive pressure system should refer to GB/T3836.1 and GB/T3836.5.
If your equipment is looking to apply for the explosion-proof 3C certification and enter the explosion-proof market, hurry up and send us a private message!
ZhongNuo Inspection has been deeply involved in the explosion-proof field for many years, familiar with the technical requirements of GB/T3836 and EN/IEC60079 explosion-proof standards.
Provide explosion-proof product modification and design guidance, and one-stop certification explosion-proof technology solutions.

In July 2019, the market issued an implementation announcement regarding the transition of explosion-proof electrical products and others from production licenses to mandatory product certification.
The announcement clearly states that as of October 1, 2019, explosion-proof electrical equipment, household gas appliances, and household refrigerators with a rated volume of over 500L will be included in the CCC certification management scope. Moreover, a transition period of 1 year is provided.
As of October 1, 2020, the above products have not obtained the mandatory product certification and are not marked with the mandatory certification logo.
Not for sale, distribution, import, or use in any business activities.
This means that in the future, applying for explosion-proof certification for enterprises will become a mandatory CCC certification, and will be implemented in accordance with the rules of the mandatory CCC certification.

Can a foreign explosion-proof certification be converted to a Chinese CCC explosion-proof certification? What documents are required?
ZhongNuo Inspection: No, the foreign explosion-proof certification Testing unit is not our CCC laboratory, so the issued Report is not recognized.
In the future, imported products listed in the CCC Catalog must undergo the CCC certification process in China.
