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 we offer services such as application assistance and factory audit guidance for this certification.
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 audit.
In short, all you need to do to obtain the explosion-proof certification is to submit a sample for testing. Once the testing passes, the certificate can be issued.
And applying for the explosion-proof CCC certification not only requires the product testing to be qualified,
Further production quality system audits of the product manufacturing facility are required (i.e., what we commonly refer to as 'auditing the factory').
For applicants, having a production facility is a must for obtaining the防爆CCC certification.

Do I need to do an explosion-proof design before applying for the explosion-proof 3C certification for the product?
That's for sure.
The product undergoes an 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 must refer to GB/T3836.1 and GB/T3836.4 for intrinsic safety.
The design of positive pressure should refer to GB/T3836.1 and GB/T3836.5.

What are the requirements for obtaining coal safety certification and mine safety certification?
Coal Safety Certification and Mine Safety Certification are mandatory certifications for mining products and equipment.
Coal safety certification is for equipment used in coal mines, while mine safety certification is for non-coal mine equipment.
Certificates are all applied for, reviewed, and issued at the Anbang Standardization Center. The validity of the certificates is 5 years, and they must undergo supervision and review annually.
Both coal safety certification and mine safety certification applications require two parts: product testing and factory inspection.
The applicant must possess design and development capabilities, and provide complete product design drawings.
And require an in-house production facility. Some products can also apply for coal safety certification and mine safety certification through OEM.
If distributors or end-users do not meet these criteria, they are not eligible to apply for the Coal Safety and Mine Safety Certification.
Shenzhen Zhongnuo Testing is a coal safety and mine safety certification and inspection organization, well-versed in the standards and requirements.
A team of engineers and factory audit service professionals.
We offer services including online application, product design and modification, drawing and document revision, and factory inspections.
Facilitate businesses in obtaining Coal Safety and Mine Safety certifications smoothly.
Our successful cases include light boxes, remote controls, fiber optic temperature measurement devices, sensors, air compressors, mobile phones, thermal imaging cameras, and patrol robots.
