Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd. specializes in explosion-proof CCC certification consulting services and boasts an extensive portfolio of consulting cases in this field. We are well-versed in the application process and technical requirements for explosion-proof 3C certification, providing clients with consulting services such as application assistance and factory audit guidance.
Which organization can apply for the explosion-proof 3C certification and 3C factory audit?
Intrinsically Safe 3C Certification is for the electrical products listed under the Intrinsically Safe 3C Catalog.
Adopt the "Type Test + Factory Audit" approach, where the factory can be its own manufacturer, or an OEM or ODM factory.
This certification is divided into two sections.
Firstly, product testing is conducted in accordance with the GB/T3836 standard for explosion-proof testing. Upon successful testing, a type examination report is issued.
Firstly, conducting factory audits, which we refer to as "factory inspections," involves on-site evaluations of production facilities.
There are numerous 3C certification agencies, but finding one capable of handling explosion-proof 3C certification is crucial.

Basic Procedure for Applying for a防爆CCC Certification
A. Submit a 3C certification application for explosion-proof electrical equipment online. The documents submitted include:
(1) Certification Application Form
(2) Certificate of registration for the certifying party, producer, and manufacturing enterprise;
(3) Product Description, including: technical specifications, structure, model descriptions, list of key components and materials, and explanations of differences between 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 inspection reports, etc.
(6) Manufacturer Information Sheet (for factory inspection)
(7) ODM Model: Provide the relevant documents as required by the supplementary regulations of CQM02-C1 "Supplementary Regulations for the ODM Model in CCC Certification," such as the ODM agreement.
(8) OEM Model: OEM agreements, etc.
(9) Proof of relevant change projects for change applications.
(10) Any other required documents.
B. Review application documents
Applications are typically reviewed within 2 business days.
C. Laboratory Testing
After the institution's review materials are approved, schedule the Testing task to the lab within 2 working days.
Lab Selection:
Sample Submission Requirements: Samples to be submitted according to laboratory specifications
D. Testing Cycle
Timeline: Generally, a Testing Report will be issued within 30 working days after the sample is confirmed, subject to the complete information provided by the customer and the requested explosion-proof type. If there are adjustments during the testing process, the adjustment time will not be included. For composite types or tests with complex projects and long cycles, the testing time will be extended accordingly.
F. Provide Testing Report
(1) Non-compliance with mandatory testing must be rectified within 3 months.
(2) If the Testing Report remains unissued for 12 months after issuance due to customer reasons, the Testing Report will become invalid.
G. Initial Factory Inspection
(1) Typically, an initial factory inspection is scheduled within 3 working days after the type test is completed.
(2) Audit takes 2-6 person-days, calculated based on unit quantity and the number of relevant personnel in the company.
(3) Audit Criteria: Factory quality assurance capability and product consistency.
(4) Corrective actions for non-conformities in factory inspections must be completed within 40 days.
(5) Factory inspection results will be reviewed within 5 working days
H - Frequent Certification
The organization conducts a 5-workday review following the submission of the type test and factory reviewing report. A Certificate is issued upon successful review.

What is the relationship between the explosion-proof certificate and the explosion-proof CCC certification?
Which certification is required for a company's explosion-proof products to enter the market? What are the requirements for the applicant company, etc.? These are many of the current dilemmas faced by businesses.
Below, China Nuofa Inspection explains it in plain language for everyone's understanding.
Firstly, both explosion-proof certification and explosion-proof CCC certification are certification requirements for explosion-proof equipment.
Whether to obtain an explosion-proof certificate or explosion-proof CCC certification mainly depends on the product category.
In layman's terms, it's about checking if your product is listed in the防爆CCC certification product catalog.
Yes, it requires the explosion-proof CCC certification; no, then obtain the explosion-proof compliance certificate.
