Shenzhen ZhongNuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof CCC certification. We have an extensive portfolio of consulting cases in the field of explosion-proof 3C certification. We are well-versed in the application process and technical requirements for explosion-proof 3C certification, and can provide services such as application assistance and factory audit guidance.
What are the requirements for enterprises to apply for explosion-proof certification and explosion-proof CCC certification?
This primarily distinguishes between two certification modes. The explosion-proof certificate adopts a type test certification model.
The explosion-proof CCC certification is conducted through a combination of type testing and factory inspection.
In a nutshell, you just need to send samples for Testing to obtain a防爆 certification; once the Testing passes, the certificate is issued.
And applying for the explosion-proof CCC certification not only requires the product to pass the testing.
A factory production quality system audit (commonly referred to as "auditing the factory") is still required.
For applicants, obtaining the防爆CCC certification requires having a manufacturing facility.

The防爆3C certification is a mandatory certification for explosion-proof electrical equipment listed in the防爆3C catalog.
A combination of type testing and factory audits is adopted. Currently, the mandatory certification for some explosion-proof products has been implemented for over a year.
Many corporate clients are gradually becoming aware of and familiar with the explosion-proof 3C certification.
To learn about specific product catalogs, certification standards requirements, and the process, please consult Shenzhen ZhongNuo Testing Technology Co., Ltd.!

After the explosion-proof CCC certification has replaced the production license, do we still need an explosion-proof compliance certificate?
Since the issuance of the market supervision regulations regarding explosion-proof electrical products and the like in July 2019
Following the announcement of the transition from production license to mandatory product certification management implementation requirements,
Many companies producing explosion-proof electrical products have gained a certain understanding of the explosion-proof 3C certification system.
But, does the implementation of the explosion-proof 3C certification system replace the original explosion-proof qualification certificate?
Does the product need an explosion-proof certification to enter the market?
What are the additional requirements for a company to produce explosion-proof electrical products?
Actually, a careful reading of this announcement reveals that...
The announcement only includes a portion of explosion-proof electrical products within the scope of mandatory product certification.
(For details, refer to the product catalog of the mandatory explosion-proof electrical product certification.)
There are still a large number of explosion-proof products not included in the market.
Common items include pressure transmitters, flammable gas detectors, breathing valves, dust removal equipment, and mechanical products.
Extraneous explosion-proof equipment installed and used in explosive areas must strictly comply with the requirements of the GB/T3836 series explosion-proof standards.
Obtain the corresponding explosion-proof certification.

What test items are required to apply for an explosion-proof certificate?
Explosion-proof products require passing relevant test requirements of the explosion-proof standards 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 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.
Flameproof products primarily undergo tests including heat and cold resistance tests, internal ignition without propagation of explosion, shell pressure resistance, IP testing, temperature rise tests, etc. Different testing items,
For different modules or components of the product, each test item ensures that the product meets the explosion-proof standards and achieves the required explosion-proof performance.
If a company is designing explosion-proof products and is not familiar with the explosion-proof standards requirements,
ZhongNuo Inspection offers guidance services for explosion-proof circuit design and explosion-proof structural design.
Including explosion-proof standards, design key points, drawings guidance, and offering agency services for explosion-proof testing and certification.
