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.
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. However, some equipment like large-scale system devices and explosion-proof lighting fixtures are not listed. They still require the original application process for an explosion-proof certification and obtaining the certificate before use in explosive hazardous areas.

How to apply for an explosion-proof certificate? Which units issue explosion-proof certificates?
The explosion-proof certificate is a certification that ensures the safety of equipment used in explosive environments.
The certification standards are the GB/T 3836 series. The process for enterprises to apply for an explosion-proof qualification certificate is relatively simple.
Please provide the electrical schematic, assembly drawing, structural diagram, product manual, and corporate standards documentation for the product.
Provide samples for explosion-proof testing that match 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 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.
If the company is new to explosion-proof product design and certification, Shenzhen Zhongnuo Testing Technology Co., Ltd.
We offer specialized intrinsic circuit design and product services, including intrinsic design, circuit evaluation, structural design, and drawing guidance, among other consulting services.
Successful cases include various sensors, instruments, automation equipment, and robotic products.

Explosion-proof product certification generally refers to the safety certification for explosion-proof products entering the market, commonly known as explosion-proof certification, with the certificate being called an Explosion-Proof Certificate.
CCC Certification, which stands for "China Compulsory Certification," is abbreviated as CCC.
The CCC certification mark is "CCC," which is recognized and supervised by the Certification and Supervision Administration according to the "Regulations on Compulsory Product Certification."
Product Certification System established by the China Quality Supervision, Inspection and Quarantine Order No. 5.

What is the difference between the corrosion protection grade, the protection grade, and the explosion-proof certification grade?
Many corporate clients are often in the dark about the required corrosion resistance, protection, and explosion-proof certification levels for their products.
Due to the only one-character difference between the names, and both referring to a specific grade of the product.
Similar yet different, what are the differences between them?
Corrosion prevention involves measures taken to protect metals prone to rust, thereby extending their lifespan. 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 level, commonly known as IP rating, refers to the dust and water resistance of the equipment, usually consisting of "IP" followed by two digits.
The explosion-proof rating generally refers to the certification level of a device's explosion-proof capabilities. Each electrical equipment applying for an explosion-proof certification will have a corresponding explosion-proof mark, including the type of explosion-proof and the explosion-proof rating. The explosion-proof rating indicates the product's applicable explosion-proof area, gas/dust groups, temperature groups, and the level of equipment protection, among other factors.
Clearly, these three concepts belong to different fields and are distinct from each other.
