Application Process for Explosion-Proof Certification at Shenzhen Zhongnuo Testing Technology Co., Ltd.
1. Conduct product assessment and initial quotation for the applied product. Assess the product based on the company's product specifications, electrical schematics, and component list, determine the appropriate type of explosion-proof certification for the product, and provide an initial quotation.
2. Provide samples for laboratory testing; the quantity of samples required varies depending on the product category.
3. Provide Documentation List Review
Application documents, including applicant's information.
(2) Technical documents, including the submitted technical materials by the company, such as corporate standards or technical requirements, product drawings, user manuals, etc.
A. Corporate Standards/Technical Requirements: The corporate standards/technical requirements for the product should be written in the prescribed format, including not only the performance requirements of the product but also relevant content regarding explosion-proof aspects: such as basic parameters, explosion-proof markings, operating environmental conditions, explosion-proof performance requirements, relevant tests for explosion-proof performance, and markings related to explosion-proof.
B. Product Drawings: When applying for a防爆 certification for intrinsically safe electrical equipment, the applicant should provide assembly drawings, circuit diagrams, printed circuit board drawings, silk-screening drawings, material lists of components, and label drawings, etc. For non-intrinsically safe electrical equipment, the technical documents submitted for inspection should include drawings that reflect the sample's explosion-proof performance (including assembly drawings and component drawings). If the assembly drawing clearly indicates the product's explosion-proof parameters and structure, only the assembly drawing needs to be submitted for inspection.
C. Instruction Manual - The instruction manual should include basic parameters, explosion-proof symbols, product外形 diagrams, installation, maintenance, order instructions, and clear warnings to the user regarding the importance of ensuring the product's explosion-proof performance during installation and use.
D. Other Information: For products with adhesive bonding or casting, provide the型号 names, performance descriptions, and relevant process documents for the adhesive and casting agents. For products with plastic casings, provide the material and corresponding performance documents.
4. Certificate of Origin

Classification of Explosion-proof Certification -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
Blast-proof certification is the process of determining if equipment meets the requirements of explosion-proof standards, type testing, and applicable routine tests, and issuing the relevant qualification certificates. Certificates can be issued for Ex equipment or Ex components.
Different regions have varying certification standards and systems for explosion-proof electrical products. Currently, international explosion-proof certifications include domestic explosion-proof certification, ATEX certification, IECEx certification, and North American explosion-proof certification.

What are common misconceptions about obtaining explosion-proof certification for products?
The explosion-proof grade is not the higher, the better.
Explosion-proof ratings are related to product structure, installation methods, and usage locations; choose the appropriate one. Of course, as long as the product structure meets the requirements, the higher the explosion-proof rating, the wider the range of applications.
2. Explosion-proof rating is not equivalent to protection rating.
The protection rating, commonly referred to as IP rating, is different from the explosion-proof rating.
3. The lower the temperature range, the safer it is, rather than the higher the better.
The temperature group indicates the high surface temperature reached by the equipment under adverse conditions. In explosive hazardous areas, of course, the lower the high surface temperature of the equipment, the safer it is.
4. Gas explosion-proof certificates cannot be used in dust areas, and conversely, dust explosion-proof certificates cannot be used in gas areas.
5. The explosion-proof design is safer than intrinsic safety. Many clients believe that having an explosion-proof housing provides more safety than intrinsic safety, which is a misconception. These are different types of explosion-proofing, all of which can achieve explosion-proofing, and if they are suitable for the product structure and environment, they are safe.
Welcome to DM Shenzhen Zhongnuo Testing Technology Co., Ltd. for detailed communication.

Is ATEX 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 hazardous areas.
To meet the explosion-proof certification standards, certain measures must be taken, which we refer to as explosion-proof protection types.
Currently common explosion-proof protection types include intrinsic safety, flameproof, positive pressure, and increased safety, etc.
Clearly, intrinsically safe is just one type of explosion-proof protection.
Different explosion-proof protection types have different design requirements for the product.
intrinsic safety is a type of explosion-proof protection that limits electrical energy, ensuring that even in the event of a fault, the energy produced is not sufficient to ignite the surrounding explosive environment.
Therefore, intrinsic safety requirements for electrical equipment include limitations on current, voltage, capacitance, inductance, etc., and are generally suitable for low-power devices.
Additionally, specific requirements are in place for the power supply method, casing material, and wireless transmission of explosion-proof equipment.
As a third-party consulting agency specializing in explosion-proof certification, ZN Testing has dedicated engineers in intrinsically safe circuit and structural design. We offer technical consulting services for explosion-proof circuit design, drafting, and modifications, and have extensive experience in designing and obtaining certifications for intrinsically safe ia, ib, and ic classifications.
