Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in explosion-proof CCC certification consulting services, boasting a wealth 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.
What products can apply for the intrinsic safety 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 can still function 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, etc., of electrical equipment, making it suitable only for low-power devices.
Additionally, there are specific requirements for the power supply method of intrinsically safe equipment, plastic enclosures, and wireless transmission.
The application for intrinsic safety certification requires the submission of the product's schematic diagrams, PCB layouts, and so on.
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 intrinsic safety levels ia, ib, and ic.

What requirements do applicants need to meet after the explosion-proof electrical products are converted to a mandatory product certification (CCC certification)?
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 test projects are required to apply for an explosion-proof certification?
Explosive-proof products require passing relevant tests according to explosive-proof standards to obtain an explosive-proof certificate.
Different explosion-proof types, catering to equipment used in various explosive environments, require different explosion-proof testing items.
Many clients also want to know what specific testing projects are required for explosion-proof products? What are the specific requirements for the explosion-proof design of the products?
Next, let's take a look at some common explosion-proof testing items.
For example, with intrinsic safety products, general test items include appearance and structure inspection, spark ignition test, dielectric strength, battery and battery pack testing, temperature rise test, transient energy test, etc.
Flameproof products primarily undergo tests including heat and cold resistance tests, internal ignition without propagation of explosion, shell pressure resistance, IP testing, temperature rise tests, etc.
Diverse test items, tailored to different modules or components of the product.
Each test item ensures that the product meets explosion-proof standards and achieves the required explosion-proof performance.
If a company is designing explosion-proof products without understanding the explosion-proof standards requirements,
ZhongNuo Inspection can provide guidance services for explosion-proof circuit design and explosion-proof structural design.
Including explosion-proof standards, design key points, drawing guidance, and offering agency services for explosion-proof testing and certification.
