What are the requirements for companies applying for the mandatory product certification (CCC certification) after the explosion-proof electrical products are converted?
ZhongNuo Inspection: Mandatory Product Certification, also known as CCC Certification, involves a certification model of Type Testing + Initial Factory Inspection + Post-Certification Supervision. In simpler terms, it requires a factory audit. The applicant must have the capability for production/inspection/shipping (or OEM/ODM).

What products can apply for the intrinsically safe explosion-proof certification? What are the requirements?
"An intrinsically safe design is one of the many explosion-proof protection types, which limits electrical energy so that the equipment remains safe even in the event of a fault."
A type of explosion-proof protection that the energy produced is not sufficient 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, there are clear requirements for the power supply method of intrinsically safe equipment, plastic enclosures, and wireless transmission.
The product application for intrinsic safety certification requires the submission of the product's schematics, PCB layouts, and so on.
ZhongNuo Inspection has dedicated engineers specializing in intrinsic safety 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 intrinsic safety levels ia, ib, and ic.
If you need certifications in this area, welcome to message Shenzhen Zhongnuo Testing Technology Co., Ltd. directly!

What standards are used for explosion-proof certification? What are the technical requirements?
An explosion-proof type is a type of explosion-proofing for electrical equipment.
The shell can withstand explosive mixtures entering the interior through the shell's joint surfaces or structural gaps, without being damaged upon internal explosion.
And causes ignition of an explosive gas atmosphere formed by one or more gases or vapors.
Explosion-proof casings must possess both anti-explosion and explosion-proof properties. Generally, the casings for explosion-proof products tend to be rather bulky.
Products and equipment suitable for fixed installation and use.
Combustion-proof interface width, gap, and roughness are the three key elements of explosion-proof housing design.
Design requirements for explosion-proof three elements vary depending on the different explosive gas environments in mining Class I, non-mining Class IIA, IIB, and IIC.
Please refer to the design standards of GB/T3836.1 and GB/T3836.2 for specifics.
ZhongNuo Inspection has long been dedicated to explosion-proof product design, testing, and certification services.
Our team in the explosion-proof field is well-versed in the requirements of explosion-proof standards.
We offer explosion-proof housing design, drafting, modification guidance, certification agency services.
