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 can provide clients with consulting services such as application assistance and factory audit guidance.
What standards are used for explosion-proof certification? What are the technical requirements?
Explosion-proof is a type of explosion-proofing for electrical equipment.
The housing is designed to withstand explosive mixtures entering through the housing joint surfaces or structural gaps, allowing for internal explosions without damage.
And ignition of an explosive gas atmosphere formed by one or more gases or vapors.
The explosion-proof housing must possess both explosion-proof and anti-explosion capabilities. Generally, the housing of products designed for explosion-proof purposes tends to be rather bulky.
Products and equipment suitable for fixed installation and use.
The three key elements of explosion-proof shell design: the width of the explosion-proof joint face, the gap, and the roughness.
Design requirements for explosion-proof 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.
Zhenuo Inspection has long been dedicated to explosion-proof product design, testing, and certification services.
We have a dedicated team in the explosion-proof field, well-versed in explosion-proof standard requirements.
We offer explosion-proof housing design, drafting, modification guidance, certification agency services.
If you have a need for this as well, feel free to consult Shenzhen ZhongNuo Inspection Technology Co., Ltd. at any time!

Composite explosion-proof products with a certificate of explosion-proof compliance are not listed in the explosion-proof CCC catalog, but the components inside are. How should this be handled?
ZhongNuo Inspection: If components are self-manufactured, a CCC certificate must be applied for. If purchased externally, components with a CCC certificate must be procured.

We generally refer to explosion-proof product certification as the safety certification for explosion-proof products entering the market, commonly known as explosion-proof certification, with the certificate being called an explosion-proof qualification certificate.
CCC Certification, which stands for "China Compulsory Certification," is also known as "China Compulsory Certification."
Abbreviated as CCC. The CCC certification mark is "CCC," which is recognized and supervised by the Certification and Supervision Commission according to the "Administrative Measures for Compulsory Product Certification."
Product Certification System established under the (China Quality Supervision, Inspection and Quarantine Order No. 5).

Which products can apply for the intrinsically safe explosion-proof certification? What are the requirements?
Bain 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 impose limitations on the current, voltage, capacitance, inductance, and other parameters of electrical equipment.
Suited for low-power equipment.
Additionally, specific requirements are in place for the power supply to intrinsically safe equipment, plastic enclosures, and wireless transmission.
The product application for intrinsic safety certification requires the submission of the product's schematic diagram, PCB diagram, etc.
Zhenuo Inspection has dedicated engineers specializing in intrinsically safe circuit and structural design.
We offer technical consultation services for explosion-proof circuit design, drafting, and modifications.
We have extensive design and certification experience for intrinsically safe IA, IB, and IC explosion-proof ratings.
