Basic Content of Factory Audit for Explosion-Proof CCC Certification:
A. Factory inspection conclusions are typically categorized into four types: "Factory Inspection Passed," "Written Verification Passed," "On-Site Verification Passed," and "Factory Inspection Failed."
"Written Verification Passed" refers to the case where there are non-conformities, and the factory has taken corrective actions within the specified time, with the certification body confirming the written verification as effective, leading to a pass; "On-Site Verification Passed" indicates that there are non-conformities, the factory has taken corrective actions within the given time frame, and upon the certification body's on-site verification being effective, the factory passes the inspection.
B. Factory audits typically require corrective actions to be completed within 40 days for any non-compliant items.
C. Basic Review Items
(1) Specify if the test results are satisfactory.
(2) Are the key resources sufficient to ensure product consistency or compliance with standards?
(3) Product consistency issues, such as changes in product structure and critical components, are they in compliance with the specified requirements?
(4) Existence of defects in certified products that could potentially lead to quality and safety accidents.
(5) Is the effective implementation of change and consistency control for certified products being conducted?
(6) Did the factory take corrective actions during the suspension of the certification certificate?
(7) Proper use of the CCC mark or certificate, including counterfeiting, renting, lending, misusing, selling, transferring the CCC mark or certificate, and theft of the CCC mark; Continuing to use the CCC mark or certificate after being informed of its revocation or suspension; Applying the CCC mark to products without a valid CCC certificate; Other intentional illegal uses of the CCC mark or certificate;
(8) Does the factory obtain certification certificates through means such as fraud or bribery?

Does the explosion-proof certification include the explosion-proof 3C certification?
Currently, in China, explosion-proof certifications are divided into Explosion-proof 3C Certification and Explosion-proof Certificate Certification.
The explosion-proof certificate and the explosion-proof 3C certification are for different types of explosion-proof products, belonging to different certification models.
As of October 1, 2009, a portion of explosion-proof electrical equipment was included in the CCC certification catalog, which is a mandatory product certification.
Products listed in the catalog are subject to explosion-proof 3C certification, adopting a "Product Testing + Factory Audit" model.
Both product type tests and factory on-site evaluations must be conducted.
Ex-proof Certificate applies to products not listed in the Ex-proof 3C Catalog. The certification model is Product Testing; upon successful completion of Product Testing, an Ex-proof Certificate can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for explosion-proof certifications alone, but there's a risk of being penalized by market regulation. This is something the client needs to consider on their own. When inquiring, the client should first confirm the type of product and then decide on the certification model.
If you're unsure whether the product is listed in the explosion-proof 3C catalog.
