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 offer services such as application assistance and factory audit guidance for this certification.
How can a company apply for a防爆 CCC certification?
1. Self-Application: The company applies directly to the certification body, prepares relevant documents independently, assists in debugging prototypes, and modifies any irregularities in the documents. The process is relatively longer, with higher overall costs, and requires more time and effort.
2. Agent Application: The application process involves a specialized explosion-proof electrical equipment technical consulting service agency (such as Shenzhen ZhongNuo Testing Technology Co., Ltd.) handling the entire consultation and application process, including material modifications, prototype debugging, and progress coordination. The progress is well-guaranteed. Fast certification, controllable overall costs, and time-saving efforts.

Sample requirements for applying for the explosion-proof CCC certification:
The sample machine submitted by the company must match the approved drawings and be fully assembled; the number of inspections should meet the requirements.
If special disassembly tools are required, they should be sent along with the goods.
For potting type electrical equipment, a set of both potted and unpotted products should be submitted.
Observing window transparent pieces should be supplied additionally with 5 pieces, at least 3.
Translucent parts for lighting fixtures should be separately sent in 8 pieces, with at least 5.
Rubber aging tests should provide 3 to 5 pieces of 35156 rubber blocks.
Insulation resistance measurement of plastic housing requires the provision of 2 plastic sheets with a diameter of 15060. If the size permits, the measurement can be directly conducted on the plastic housing.
Finished products usually require 1-2 units.

Requirements for application of防爆CCC certification:
1. Product Drawings and Documents: When applying for a防爆ex-proof certificate for intrinsic safety electrical equipment, the applicant should provide assembly drawings, circuit diagrams, printed circuit board layouts, silk-screened diagrams, component material lists, and label drawings, etc. For non-intrinsic safety electrical equipment, the technical documents submitted for inspection should include drawings that reflect the sample's explosion-proof performance (including assembly drawings and component drawings). If the assembly drawing can clearly indicate the product's explosion-proof parameters and structure, only the assembly drawing needs to be submitted for inspection.
2. Technical Documents: Include corporate standards/technical requirements. The corporate standards/technical requirements for the product should be written in accordance with the specified format. The content should not only include performance requirements of the product but also cover relevant aspects of explosion-proof: 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型号 names, performance descriptions, and relevant process documents for the adhesive and casting agents. For products with plastic casings, include the material of the plastic and corresponding performance documents. Products with batteries require the relevant specifications for the batteries.
