Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd. specializes in consulting services for explosion-proof CCC certification. We have a wealth 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 clients with consulting services such as application submission and factory audit guidance.
Requirements for application of explosion-proof 3C certification:
Certificate Application Form
(2) Certified Applicant, Manufacturer, and Manufacturer's Registration
(3) Product Description, including: technical specifications, structure, model descriptions, list of key components and materials, and explanations of differences among products of different specifications within the same certification unit.
(4) Technical documents, mainly including: product standards (or technical specifications), manuals, product drawings related to explosion-proof performance, etc.
(5) Certificate of Compliance for test samples, Factory Testing Report, etc.
(6) Manufacturer Information Sheet (for factory inspection)
(7) ODM Model: Provide the relevant documents as required by the supplementary regulations for the ODM Model in CQM02-C1 "Supplementary Regulations for the ODM Model in the CCC Certification," such as the ODM agreement.
(8) OEM Model: OEM agreements, etc.
(9) Documentation for related change request projects;
(10) Any other required documents.

Basic contents of factory audit for explosion-proof CCC certification:
A. Factory Audit Conclusions are typically categorized into four types: "Factory Audit Passed," "Documentation Verification Passed," "On-site Verification Passed," and "Factory Audit Not Passed."
"Written Verification Passed" refers to the case where there are non-conformities, the factory takes corrective actions within the specified time frame, and the certification body verifies the written report as effective, resulting in a pass; "On-Site Verification Passed" indicates that there are non-conformities, the factory implements corrective measures within the designated period, and upon successful on-site verification by the certification body, the factory passes the inspection.
B. Factory audits require rectification of any non-conformities within 40 days typically.
C. Basic Review Items
(1) Specify if the test results are qualified.
(2) Do the key resources meet the requirements for ensuring product consistency or compliance with standards?
(3) Consistency issues with the product, such as changes in product structure or critical components, whether they meet the specified requirements.
(4) Determine if the certified products have defects that may lead to quality safety accidents.
(5) Is the effective implementation of change and consistency control for certified products in place?
(6) Did the factory take corrective actions during the suspension of the certification certificate?
(7) Proper use of the CCC mark or certificate, including forgery, rental, lending, misuse, sale, transfer of the CCC mark or certificate, and theft of the CCC mark; continued use of the CCC mark or certificate after being notified of its revocation or suspension; intentionally affixing the CCC mark on products without a valid CCC certificate; other deliberate illegal uses of the CCC mark or certificate.
(8) Does the factory have any instances of obtaining certification certificates through deceit, bribery, or other improper means?
(9) Are there any other circumstances that directly threaten product consistency or compliance with standards?

What products can apply for the intrinsically safe explosion-proof certification? What are the requirements?
Bain is one of the many explosion-proof protection types, which limits electrical energy so that the equipment remains safe even in the event of a fault.
A type of explosion-proof protection that the energy produced is not sufficient to ignite the surrounding explosive environment.
Therefore, intrinsic safety requirements impose limitations on electrical equipment's current, voltage, capacitance, inductance, etc., making it suitable only for low-power devices.
Additionally, there are specific requirements for the power supply method of intrinsically safe equipment, plastic enclosures, and wireless transmitters.
The product application for intrinsic safety certification requires the submission of the product's schematic diagram, PCB diagram, etc.
ZhongNuo Inspection has dedicated engineers specializing in intrinsically safe circuit and structural design.
We offer technical consulting services for explosion-proof circuit design, drafting, and modification. We have extensive experience in designing and obtaining certifications for intrinsically safe ia, ib, and ic explosion-proof classifications.

What's the difference between ATEX certification and CE certification?
CE certification is a mandatory certification for the European Union market, and all equipment and products entering the EU market must pass the relevant CE directive certification.
For example, there are EMC directives, LVD directives, MD directives, ATEX directives, etc.
Different products are subject to different certification directives; the ATEX directive is specifically for explosion-proof equipment and products.
ATEX certification can be considered the CE certification for explosion-proof products.
Each directive has different applicable standards; the ATEX directive applies to the EN60079 series.
Different explosion-proof types are applicable to various standard series.
For instance, EN 60079.1 is the standard for explosion-proof, EN 60079.7 is the standard for increased safety, and EN 60079.11 is the standard for intrinsic safety, etc.
