What test projects are required to apply for an explosion-proof certification?
Explosive-proof products must pass relevant test requirements of the explosive-proof standards to obtain an explosive-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 testing projects are required for explosion-proof products? What specific requirements are there for the explosion-proof design of the product?
Next, let's give some examples of common explosion-proof testing items.
For example, with intrinsically safe products, general test items include appearance and structure inspection, spark ignition test, dielectric strength, battery and battery pack testing, temperature rise test, transient energy test, 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 testing, among others. Different testing items,
For each module or component of the product, every test item ensures that the product meets the explosion-proof standards and fulfills the requirements for explosion-proof performance.
If a company is designing explosion-proof products without understanding the explosion-proof standards requirements,
Zhenuo Inspection can provide guidance services for explosion-proof circuit design and explosion-proof structural design.
Including explosion-proof standards, design key points, drawing guidance, and we can also handle explosion-proof testing and certification services.

What is the relationship between the explosion-proof certificate and the explosion-proof CCC certification?
Which certifications are required for a company's explosion-proof products to enter the market? What are the requirements for the applicant companies, etc.? These are many of the current dilemmas faced by enterprises.
Below, China Nuodong Testing breaks it down for you in plain language.
Firstly, both explosion-proof certificates and explosion-proof CCC certifications are certification requirements for explosion-proof equipment.
Whether to obtain the explosion-proof certificate or the explosion-proof CCC certification largely depends on the product category.
Put simply, it's about checking if your product is listed in the防爆CCC certification product catalog.
Yes, you need to obtain the Explosion-proof CCC Certification; no, then you just need the Explosion-proof Compliance Certificate.

Can coal safety certification be converted to explosion-proof 3C certification? - Answer from Shenzhen ZhongNuo Testing Technology Co., Ltd.
Based on the announcement, as of October 1, 2020, certain explosion-proof electrical equipment has been transferred to the mandatory product certification catalog.
It is the CCC certification. Products under the explosion-proof 3C certification category obtain the explosion-proof CCC certification by undergoing a "type test + factory audit" certification process.
Coal Mine Safety Certification, abbreviated as CMS, is a mandatory certification implemented by the Safety Standardization Center for all types of products and equipment used underground in coal mines.
The certification method combines "type testing" with "factory audit."
Currently, mandatory product certification bodies and coal safety certification bodies are under different departments.
There is no mutual recognition between them. Coal safety certification and explosion-proof 3C certification are independent of each other.
The coal safety certification or the explosion-proof 3C certification cannot be substituted or converted for each other; they must be applied for separately.
