Shenzhen ZhongNuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof CCC certification. We have an extensive portfolio of consulting cases in explosion-proof 3C certification. We are well-versed in the application process and technical requirements for explosion-proof 3C certification, and can provide consulting services such as application assistance and factory review guidance.
Do you have a product catalog for explosion-proof electrical equipment that has transitioned to mandatory product certification (CCC certification)?
Zhong Nuo Inspection: Yes. The market is transitioning from production license for explosion-proof electrical equipment to mandatory product certification at the same time.
We also issued a notice regarding the conversion of the防爆电气 production license to a mandatory certification product scope.
Products within the product catalog must be manufactured, sold, or engaged in other business activities during the transition period with a valid production license or CCC certification.
After the transitional period, only products with valid CCC certification can be manufactured, sold, or engaged in other business activities.

Which products can apply for the intrinsically safe explosion-proof certificate? What are the requirements?
Bain is one of the many explosion-proof protection types, which limits electrical energy so that the equipment can still function even in the event of a fault.
This explosion-proof type of protection does not produce enough energy to ignite the surrounding explosive environment.
Therefore, intrinsic safety requirements limit the current, voltage, capacitance, inductance, etc., of electrical equipment, making it only suitable for low-power devices.
Additionally, specific requirements are in place for the power supply method of intrinsically safe equipment, plastic housing, and wireless transmission.
To apply for the intrinsically safe certification of the product, the original circuit diagram and PCB diagram of the product must be provided.
ZhongNuo Inspection has dedicated engineers specializing in intrinsically safe circuit and structural design.
We offer technical consulting services for explosion-proof circuit design, drafting, and modifications. We have extensive experience in designing and obtaining certifications for intrinsically safe ia, ib, and ic explosion-proof ratings.
If you require certification in this area, welcome to send a private message to Shenzhen Zhongnuo Testing Technology Co., Ltd.!

How to apply for an explosion-proof certification? Which organizations issue explosion-proof certifications?
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 explosion-proof certification is relatively simple.
Please provide the electrical schematics, assembly drawings, structural drawings, product manual, and corporate standards documents for the product.
And provide samples that are consistent with the drawings for explosion-proof testing. Upon passing the test,
You can then provide the Explosion-Proof Testing Report and Explosion-Proof Compliance Certificate.
Currently, the main institutions issuing explosion-proof certificates include Nanyang CNEX, Tianjin PCEC, Shanghai NEPSI, various Coal Research Institutes, Suzhou Electric Science Institute, etc.
These institutions all hold 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.
We offer specialized intrinsically safe circuit design and product services, including intrinsically safe design, circuit evaluation, structural design, and drawing guidance.

What's the difference between the corrosion protection grade, protection grade, and explosion-proof certification grade?
Many corporate clients are often confused about the required corrosion resistance, protection level, and explosion-proof certification level for their products.
Due to the products' grades being differentiated by only one character, and both referring to the same aspect 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. This is typically achieved through physical, chemical, and electrochemical corrosion prevention methods. Common classifications include indoor F1, F2, and outdoor WF, WF1, and WF2, totaling five levels.
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 rating generally refers to the equipment's explosion-proof certification level. Each electrical equipment applying for explosion-proof certification will have a corresponding explosion-proof marking, including the type and level of explosion-proof. The explosion-proof rating indicates the product's applicable explosion-proof area, gas/dust group, temperature group, and equipment protection level, etc.
Clearly, these three concepts belong to different fields and are distinct from one another.
