What's the difference between corrosion protection grade, protection grade, and explosion-proof certification grade?
Many corporate clients are often confused about the required corrosion, protection, and explosion-proof certification levels for their products.
Due to the mere one-character difference in names, both refer to a specific grade of the product.
Similar yet different, what are the differences between them?
Corrosion prevention involves measures to protect metals prone to rust, thereby extending their service life. Typically, methods such as physical, chemical, and electrochemical corrosion prevention are employed. There are five common levels: indoor F1, F2, and outdoor WF, WF1, and WF2.
Protection rating, commonly known as IP rating, refers to the dust and water resistance level of the equipment, typically consisting of "IP" followed by two digits.
The explosion-proof grade generally refers to the equipment's explosion-proof certification level. Each electrical equipment applying for an explosion-proof certification will have a corresponding explosion-proof marking, including the type of explosion-proof and the explosion-proof grade. The explosion-proof grade indicates the product's applicable explosion-proof area, gas/dust groups, temperature groups, equipment protection level, etc.
Clearly, these three concepts belong to different fields and are distinct from each other.

Requirements for applying for the explosion-proof 3C certification:
Certificate Application Form
(2) Certified Principal, Manufacturer, and Producer Registration
(3) Product Description, including: technical specifications, structure, model descriptions, list of key components and materials, and explanations of differences between products of different specifications within the same certification unit;
(4) Technical documents, mainly including: product standards (or technical specifications), manuals, product drawings related to explosion-proof performance, etc.
(5) Certificate of Compliance for test samples, Factory Testing Report, etc.
(6) Manufacturer Information Sheet (for factory inspection)
(7) ODM Model: Provide the relevant documents as required by the supplementary regulations for the ODM Model in CQM02-C1 "Supplementary Regulations for the ODM Model in the CCC Certification," such as the ODM agreement.
(8) OEM Model: OEM agreements, etc.
(9) Documentation for related change request items
(10) Additional required documents.

How do I apply for an explosion-proof certificate? Which organizations issue explosion-proof certificates?
The explosion-proof certificate is a certification for the safety of equipment used in explosive environments.
The certification standards are the GB/T 3836 series. The process for a company to apply for an explosion-proof qualification certificate is quite simple.
Please provide electrical schematics, assembly drawings, structural diagrams, product manuals, and corporate standards documents for the product.
Provide samples for explosion-proof testing that conform to the provided drawings and documentation. Upon passing the test,
You can then issue the explosion-proof Testing Report and the explosion-proof qualification certificate.
Currently, the main issuing bodies for explosion-proof certification include Nanyang CNEX, Tianjin PCEC, Shanghai NEPSI, various Coal Research Institutes, Suzhou Electric Science Institute, and others.
These institutions all have comprehensive Certificates, with equal validity.
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.
If your company is new to explosion-proof product design and certification, turn to Shenzhen ZhongNuo Testing Technology Co., Ltd.

Requirements for application of the防爆CCC certification:
1. Product Drawings and Documents: When an enterprise applies for a explosion-proof certificate for intrinsically safe electrical equipment, it should provide assembly drawings, circuit diagrams, printed circuit board drawings, silk-screened diagrams, material lists for components and labels, etc. 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 can clearly indicate the explosion-proof parameters and structure of the product, only the assembly drawing needs to be submitted for inspection.
2. Technical Documentation: Includes company standards/technical requirements. The company standards/technical requirements for the product should be written in the specified format, with content covering not only performance requirements of the product but also relevant explosion-proof 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, please provide the model names, performance descriptions, and relevant process documents for the adhesives and casting agents. For plastic shell products, include the material of the plastic and corresponding performance documents. Battery-operated products require the provision of relevant battery specifications.
