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 can provide clients with consulting services such as application assistance and factory audit guidance.
Does the explosion-proof certification include the explosion-proof 3C certification?
Currently, domestic explosion-proof certifications include the Explosion-Proof 3C Certification and the Explosion-Proof Qualification Certificate.
The explosion-proof certificate and explosion-proof 3C certification are for different types of explosion-proof products, each belonging to a separate certification model.
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 within the catalog undergo explosion-proof 3C certification, adopting the "Product Testing + Factory Audit" model.
Both product type testing and factory on-site evaluation are required.
Ex-proof certificate is applicable to products not listed in the Ex-proof 3C Catalogue. The certification model is Product Testing; upon successful Product Testing, an Ex-proof certificate can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for just the explosion-proof certification, but there's a risk of being penalized by market regulation. This is something for the customer to consider on their own. When consulting, the customer should first confirm what type of product it is, and then decide on the certification model.
If you're still unsure whether the product is on the Intrinsic Safety 3C Catalogue.

What standards are used for explosion-proof certification? What are the technical requirements?
An explosion-proof type is a type of explosion-proofing for electrical equipment.
The housing is designed to withstand explosive mixtures entering the housing through the housing joint surfaces or structural gaps, and to withstand internal explosions without damage.
And causes ignition of an explosive gas atmosphere formed by one or more gases or vapors.
The explosion-proof housing must have both explosion-proof and anti-explosion capabilities. Generally, the outer casings of products designed for explosion-proofing are rather bulky.
Products and equipment suitable for fixed installation and use.
The three essential elements of explosion-proof housing design: width of the隔爆 joint face, gap, and roughness.
Design requirements for explosion-proof triad elements differ according to the different explosive gas environments in mining Class I, non-mining Classes IIA, IIB, and IIC.
Refer to the design standards of GB/T3836.1 and GB/T3836.2 for specifics.
ZhongNuo Inspection has long been dedicated to explosion-proof product design, testing, and certification services.
Our team in the explosion-proof field is well-versed in the requirements of explosion-proof standards.
We offer explosion-proof housing design, illustration, modification guidance, and certification agency services.

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, the factory takes corrective actions within the specified time, and the certification body's written verification is deemed effective, leading to a pass for the factory inspection; "On-Site Verification Passed" means there are non-conformities, the factory implements corrective actions within the given time frame, and upon successful on-site verification by the certification body, the factory inspection passes.
B. Factory audits typically require rectification of any non-compliant items to be completed within 40 days.
C. Basic Review Items
(1) Specify if the test results are satisfactory.
(2) Does the key resource 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, are they in compliance with the specified requirements?
(4) Existence of defects in certified products that could potentially lead to quality safety incidents.
(5) Is the effective implementation of product certification changes and consistency control in place?
(6) Has the factory taken corrective actions during the certification certificate suspension period?
(7) Proper use of the CCC mark or certificate, including forgery, rental, lending, misuse, sale, transfer, and theft of the CCC mark or certificate; continuing to use the CCC mark or certificate after being notified of its revocation or suspension; deliberately applying the CCC mark to products without a 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?
(9) Are there any other conditions that could directly threaten product consistency or compliance with standards?
