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.
Requirements for application of防爆CCC certification:
1. Product Drawings and Documents: When a company applies for an explosion-proof certification for intrinsically safe electrical equipment, they should provide assembly drawings, circuit diagrams, printed circuit board drawings, silk-screen drawings, component material lists, and label drawings, among others. For non-intrinsically safe electrical equipment, the technical documents submitted for inspection should include drawings that reflect the explosion-proof performance of the sample (including assembly drawings and component drawings). If the assembly drawing clearly indicates the explosion-proof parameters and structure of the product, only the assembly drawing needs to be submitted for inspection.
2. Technical Documentation: Includes corporate standards/technical requirements. The corporate standards/technical requirements for the products should be written in the prescribed format, with content that includes not only performance requirements of the product but also related防爆 aspects: such as basic parameters, explosion-proof markings, operating environmental conditions, explosion-proof performance requirements, relevant tests for explosion-proof performance, and markings related to explosion-proof.
3. Additional Information: For products with adhesive bonding or casting, provide the model names, performance descriptions, and relevant process documents for the adhesives and casting agents. For plastic shell products, supply the material type and corresponding performance documents. Battery-operated products require the battery specifications to be provided as well.

Application cycle for explosion-proof 3C certification (excluding rectification and preparation time for the applicant)
1. Organization review of application materials: 2 business days
2. Issue Testing Task: Within 2 working days after completion of document review
3. Testing Cycle: Generally, provide the Testing Report within 30 working days after confirming receipt of the sample.
The delivery date is subject to the complete information provided by the customer and the type of explosion-proof certification requested. If adjustments are made during the testing process, the time for these adjustments will not be included. For composite types or tests with complex procedures and longer cycles, the testing time will be extended.
4. Factory Audit: Issue Testing Report and arrange factory audit within 3 working days. Complete factory audit within 5 working days.
5. Frequency of Verification: The institution conducts a 5-workday review after the submission of the type test and factory reviewing report, and issues a Certificate upon successful review.

Is explosion-proof product certification the same as CCC certification? — An Answer from Shenzhen Zhongnuo Testing Technology Co., Ltd.
We refer to explosion-proof product certification as the safety certification required for explosion-proof products to enter the market, commonly known as explosion-proof certification, with the certificate being called an explosion-proof compliance certificate.
CCC Certification, which stands for "China Compulsory Certification," is abbreviated as CCC.
The CCC certification mark is "CCC," which is a product certification system established by the Certification and Supervision Commission according to the "Administrative Regulations for Compulsory Product Certification" (Order No. 5 of the China Quality Supervision and Inspection and Quarantine Commission).
As of October 1, 2019, explosion-proof electrical products were officially included in the mandatory product certification scope for market supervision.
Means that some explosion-proof electrical equipment must be compulsorily applied for a 3C certification to enter the market and be circulated.
Part of the explosion-proof product certifications are included in the CCC certification scope.
But explosion-proof product certification is not equivalent to CCC certification.
Only explosion-proof products listed in the CCC Certification Catalog need to apply for the CCC Certification; explosion-proof products outside the catalog only require an explosion-proof qualification certificate.

How to obtain certification for explosion-proof electrical products outside the CCC explosion-proof product catalog?
ZhongNuo Inspection: Currently, the product catalog only includes most explosion-proof electrical equipment, but there are still some explosion-proof electrical devices.
For example, large-scale system equipment, transmitters, pressure sensors, level indicators, flammable gas detectors, flow meters, and the like are not included in the product catalog.
You still need to apply for the explosion-proof certificate as before, and obtain the explosion-proof certificate before it can be used in explosive hazardous areas.
