Electrical Control Integrated Unit Positive Pressure Certification Applicable Standards - Shenzhen ZhongNuo Inspection

Shenzhen Zhongnuo Inspection & Testing Technology Co., Ltd. is based in South China and specializes in explosion-proof certification and coal safety certification application consulting services, offering a one-stop explosion-proof technology consulting service.
Intrinsically safe certification is widely applied to low-power, energy-efficient instruments, handheld terminal products, and more. These devices generate relatively low energy levels, making it easier to control them within a safe range through technical means, thereby meeting intrinsic safety requirements. For example, temperature vibration sensors, remote transmitters, monitoring devices, Bluetooth beacons, two-way radios, and other products are all candidates for intrinsic safety certification.

What are the requirements and documents needed to apply for an explosion-proof certification?
The explosion-proof certificate is a safety certification for equipment and products used in environments with explosive gases or combustible dust.
Certificates are available for Ex equipment and Ex components.
The product must obtain a防爆 certification, requiring the submission of the product for explosion-proof standard testing and providing drawings and documentation that meet the explosion-proof standard requirements.
The technical documents here include product manuals, corporate standards, electrical schematics, PCB layouts, assembly drawings, and exploded views.
Battery Testing Report and specifications, potting process documents, wireless transmission power report, housing material report, etc.
Of course, not all this information is required; it depends on the product structure and explosion-proof type for further assessment.
ZhongNuo Inspection has years of experience in explosion-proof product certification and investigation services, offering consulting on explosion-proof design, illustration, circuit, and structural modifications.

What qualifications or certificates are required for explosion-proof construction?
The Explosion-proof Electrical Equipment Installation and Maintenance Qualification Certificate is beneficial for explosion-proof electrical construction. This certificate is one of the qualifications for companies in the explosion-proof electrical construction industry, indicating that the company and its construction personnel have passed the safety training for explosion-proof electrical construction and have mastered the relevant technologies and knowledge. It serves as the foundation for conducting explosion-proof electrical construction work.
In many construction projects, particularly those involving installations in flammable and explosive environments, owners require contractors to provide relevant explosion-proof electrical installation certifications to ensure the quality and safety of the work. Therefore, possessing this certificate can significantly enhance a company's competitiveness in the field of explosion-proof electrical installations, bringing more business opportunities to the enterprise.
Therefore, if you are in the explosion-proof electrical construction industry or plan to enter it, obtaining an explosion-proof electrical equipment installation and maintenance qualification certificate is necessary.
If you happen to need an explosion-proof qualification certificate, feel free to consult Shenzhen ZhongNuo Testing Technology Co., Ltd. at any time!

What should be noted when applying for a domestic explosion-proof certification for products?
What should be noted when applying for a domestic explosion-proof certification? Zhongnuo Testing, with years of experience in the explosion-proof certification industry, mainly shares the following points:
(1) Is the product design in compliance with the relevant standards of GB/T3836? For example, explosion-proof designs should refer to GB/T 3836.1 and GB/T 3836.2, intrinsically safe designs should refer to GB/T 3836.1 and GB/T 3836.4, etc.
(2) Can certification materials be provided, such as schematics, assembly drawings, structural drawings, BOM sheets, manuals, corporate standards, etc.? Some products may also require battery Testing Reports, Wireless Transmission Power Reports, potting process, and shell material Reports.
(3) Are there specific requirements for certification bodies and explosion-proof ratings? Sometimes, the explosion-proof certification needs are proposed by the end customer. In such cases, it is necessary to understand the type of explosion-proof environment and area where the end customer's product is used, as well as any specific requirements for the product's IP rating, corrosion resistance, and certification body.
(4) Is the company to collect evidence itself or through an agent? If the company is not familiar with explosion-proof design standards, drawing preparation, etc., and is new to obtaining explosion-proof certification, it is recommended to choose ZhongNuo Testing Application for a time, effort, and stress-saving solution.
(5) Next is the budget for costs. If you choose to apply with ZhongNuo Inspection, a service fee will be incurred. ZhongNuo Inspection can save your company on labor and material investments, shorten the application process, and contribute to the friends of the company in bringing new explosion-proof products to market.
