Why is it necessary to do explosion-proof design before applying for explosion-proof certification?
That's for sure.
The process of obtaining a explosion-proof certification for products is to pass the relevant testing projects of the explosion-proof standards and obtain an explosion-proof qualification certificate.
To ensure products pass the explosion-proof standard testing, they must be designed in accordance with the testing requirements, which is to say, they must be explosion-proof designed.
For explosion-proof requirements, refer to GB/T3836.1 and GB/T3836.2; for intrinsically safe designs, consult GB/T3836.1 and GB/T3836.4.
Designs must refer to GB/T3836.1 and GB/T3836.3, etc.

To apply for the防爆电气 CCC certification, certain conditions must be met and a specific process followed. Below is an introduction by Shenzhen Zhongnuo Testing Technology Co., Ltd. on the process and requirements for applying for the explosion-proof electrical CCC certification.
I. Application Requirements
1. Product Scope: Firstly, the explosion-proof electrical products applied for must be included in the mandatory product certification catalog (i.e., explosion-proof 3C certification). Common explosion-proof electrical products such as motors, fans, intercoms, etc., are all within this catalog. If the product is not in this catalog, it may only require an explosion-proof compliance certificate.
2. Production Factory: The applicant must have a production factory or an OEM/ODM factory. This is because the explosion-proof 3C certification adopts a "product testing + factory audit" model, which requires both type testing of the product and on-site auditing of the factory.
II. Application Process
1. Product Testing: To apply for the explosion-proof CCC certification, the samples need to be sent to the designated explosion-proof 3C certification laboratory for relevant explosion tests. The testing institution will conduct comprehensive testing and evaluation of the product's drawings, technical data, and explosion-proof performance based on relevant standards.
2. Factory Evaluation: Based on the product's passing inspection, the explosion-proof 3C certification body will conduct an on-site evaluation of the applicant's production factory. The evaluation criteria include the implementation rules and detailed procedures for the explosion-proof CCC certification, and the evaluation contents cover the factory's quality management system, production process control, raw material procurement, and other aspects.
3. Certificate Issuance: Upon successful product testing and factory audit, the explosion-proof 3C certification body will issue an explosion-proof 3C certification certificate.
III. Cautionary Notes
If the explosion-proof electrical products applied for by the enterprise are within the explosion-proof 3C certification catalog, it is mandatory to obtain the explosion-proof 3C certification, which is a mandatory requirement of market supervision.
If you have specific products requiring an explosion-proof electrical CCC certification application, or need further assistance and guidance, please feel free to contact Shenzhen ZhongNuo Testing Technology Co., Ltd. We will provide you with dedicated consultation and support.

The cost of obtaining explosion-proof certification at Shenzhen Zhongnuo Testing Technology Co., Ltd. is related to the following aspects:
1. Do you need an explosion-proof certificate or the explosion-proof 3C certification? If it's the 3C certification, a factory audit is required, which includes the audit fee, the travel expenses for the auditor, the applying fee for the 3C certificate, and the certificate fee, etc.
2. Related to explosion-proof markings. Different explosion-proof markings indicate different explosion-proof items, and naturally, the costs vary accordingly.
3. Domestic explosion-proof certification or international explosion-proof certification? The same explosion-proof mark, ATEX/IECEx certification is much more expensive than the domestic explosion-proof certificate, and it also requires factory audit. North American explosion-proof certification is even more costly, over $100,000+
4. Do you need a retest? Some customers' products haven't even undergone explosion-proof design, and they still require modifications, which adds to the cost. If the product includes batteries, battery testing is also an additional expense, especially for those batteries that keep failing the tests.
5. Needed or not. Labs are often booked solid, and there's often a waiting list. If needed, there will be a fee involved.

If you have any questions or needs regarding ATEX certification, please feel free to consult Shenzhen Zhongnuo Testing Technology Co., Ltd.
