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 can provide clients with consulting services such as application assistance and factory audit guidance.
The防爆3C certification is a mandatory certification for explosion-proof electrical equipment listed in the Explosion-Proof 3C Catalog.
Combine the methods of type testing with factory inspection.
Currently, the mandatory certification for some explosion-proof products has been in effect for over a year.
Many corporate clients are gradually becoming aware of and familiar with the explosion-proof 3C certification.

How to apply for an explosion-proof certificate? Which units issue explosion-proof certificates?
The explosion-proof certificate is a certification for the safety of equipment used in explosive locations.
The certification standards are the GB/T 3836 series. The process for enterprises to apply for an explosion-proof qualification certificate is quite simple.
Please provide the electrical schematic, assembly drawing, structural drawing, product manual, and corporate standards documentation for the product.
Provide samples that match the drawings and specifications for explosion-proof testing. Upon passing the test,
You can then issue the explosion-proof Testing Report and the explosion-proof certification.
Currently, the main issuing bodies for explosion-proof certificates include Nanyang CNEX, Tianjin PCEC, Shanghai NEPSI, various Coal Research Institutes, Suzhou Electric Science Institute, and others.
These institutions all possess comprehensive Certificates, with the validity of the certificates being identical.
Although the process is relatively simple, it's not easy to meet the design requirements of the GB/T 3836 series standards for the product.

Basic contents of factory audit for explosion-proof CCC certification:
A. Factory Audit Conclusions are generally 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, and the certification body verifies the written report as effective, resulting in a pass; "On-Site Verification Passed" refers to the situation where there are non-conformities, the factory implements corrective measures within the designated timeframe, and the certification body confirms the effectiveness of the on-site verification, leading to a pass for the factory.
B. Factory audits require rectification of any non-conformities typically within 40 days.
C. Basic Review Items
(1) Specify if the test results are satisfactory.
(2) Are the key resources adequate to ensure product consistency or compliance with standards?
(3) Product consistency issues, such as changes in product structure or critical components, are they in compliance with the specified requirements?
(4) Determine if the certified products have defects that could lead to quality safety accidents.
(5) Is the implementation of product certification changes and consistency control effective?
(6) During the suspension of the certification certificate, has the factory taken corrective measures?
(7) Proper use of the CCC mark or certificate, including alteration, rental, lending, misuse, sale, transfer, or theft of the CCC mark or certificate; 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 intentional 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 situations that directly threaten product consistency or compliance with standards?
