Shenyang Explosion-Proof Inspection Robot Safety Certification, Shenzhen ZhongNuo Inspection and Testing, what are the required conditions?

Shenzhen Zhongnuo Testing Technology Co., Ltd. is based in South China, specializing in explosion-proof certification and coal mine safety certification application consulting services, offering a one-stop explosion-proof technology consulting service.
Is "intrinsically safe certification" the same as explosion-proof certification? What are the differences between them?
Explosion-proof certification refers to a safety certification for equipment and products used in explosive hazard areas.
Products must meet the requirements of explosion-proof certification standards, and certain measures must be taken to achieve this, which we refer to as explosion-proof protection types.
Common explosion-proof protection types include intrinsic safety, flameproof, positive pressure, and increased safety, etc.
Clearly, intrinsic safety is just one type of explosion-proof protection.
Different explosion-proof protection types have varying design requirements for the product.
intrinsically safe type is designed to limit electrical energy, even in the event of a fault.
A防爆型式, where the energy produced is insufficient to ignite the surrounding explosive environment.
Therefore, intrinsic safety requirements for electrical equipment include limitations on current, voltage, capacitance, inductance, etc., and are generally applicable to low-power equipment.
Additionally, there are specific requirements for the power supply method, housing material, and wireless transmission of intrinsically safe equipment.
As a long-standing third-party consulting firm specializing in explosion-proof certification.
ZhongNuo Inspection has dedicated engineers specializing in intrinsically safe circuit and structural design.
We can provide technical consultation on explosion-proof circuit design, drafting, and modifications.
We have extensive design and certification experience for explosion-proof classifications of ia, ib, and ic.
If you need certification in this area, welcome to message us directly!

Can ODM/OEM companies apply for explosion-proof certificates and explosion-proof 3C certifications? What are the requirements?
Many clients are asking whether their products are OEM-manufactured, ODM-branded, or purchased.
Can you handle explosion-proof certification or explosion-proof 3C certification?
Here, ZN Testing introduces the requirements and conditions for obtaining explosion-proof certificates and explosion-proof 3C certifications.
If applying for an explosion-proof certification, the company only needs to provide the product's design drawings and samples.
No requirements regarding the presence of a production factory. Therefore, whether it's an OEM, ODM product, or a product purchased directly,
As long as the required drawings and samples for certification are provided, a防爆 certification can be processed.
Of course, the provided drawings and samples must comply with the requirements of the explosion-proof certification standards.
Applying for the explosion-proof 3C certification requires an additional factory audit and an annual supervisory review compared to the explosion-proof certificate.
Therefore, the applicant must have their own manufacturing factory/OEM/ODM factory.
The application process is also more complex and costly, with a longer duration, compared to obtaining the explosion-proof certification.
Zhenuo Inspection has been dedicated to the explosion-proof field for many years, well-versed in the requirements of the GB/T 3836 series standards.
Extensive experience in design and modification guidance for explosion-proof products.
We offer a one-stop service for explosion-proof certification, including design modification, drawing evaluation, certification acquisition, factory audit, and explosion-proof 3C certification.
We have a wealth of evidence collection cases and experience. Feel free to DM us!

What is the difference between ATEX certification and CE certification?
CE certification is a mandatory certification in the EU market, and all equipment and products entering the EU market must pass the relevant CE directive certification.
For example, there are EMC directives, LVD directives, MD directives, ATEX directives, etc.
Different products are subject to various certification directives; the ATEX directive, for instance, pertains specifically to explosion-proof equipment and products.
ATEX certification can be likened to the CE certification for explosion-proof products.
Each directive has different applicable standards; the ATEX directive applies to the EN60079 series.
Different explosion-proof types apply to different standard series.
For instance, EN 60079.1 is the standard for explosion-proof, EN 60079.7 is the standard for increased safety, EN 60079.11 is the standard for intrinsic safety, and so on.

Sample Requirements for Explosion-Proof Certification Application:
The sample units submitted by the company for inspection should match the approved drawings and be fully assembled; the number of units inspected should meet the requirements.
If special disassembly tools are required, they should be sent along as well.
For potting-type electrical equipment, one set of products with and without potting should be submitted.
The transparent parts for the observation window should be sent separately with at least 3 pieces, an additional 5 pieces.
The transparent parts of the lighting fixtures should be sent separately with at least 5 pieces, but no more than 8.
Rubber aging tests should provide 3 to 5 pieces of 35156 rubber blocks.
Provide 2 plastic sheets with a diameter of 15-6mm for insulation resistance testing of the plastic shell. If the size permits, the test can be directly performed on the plastic shell.
Finished products usually require 1-2 pieces.
