Shenzhen Zhongnuo Testing Technology Co., Ltd. is based in South China and specializes in explosion-proof certification and coal mine safety certification application consulting services, offering a one-stop explosion-proof technology consulting service.
The intrinsic safety certification is widely applied to low-power, low-energy instruments, handheld terminal products, and other devices. These devices produce relatively low energy, which can be easily controlled within a safe range through technical means, meeting the 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.

How to obtain the intrinsic safety certification for electrical products? What are the requirements for intrinsic safety certification?
Recently applied for products such as temperature vibration sensors, remote transmitters, monitoring devices, Bluetooth beacons, two-way radios, etc.
Ex-proof certificates are all intrinsic safety types, adhering to the standards GB/T3836.1 and GB/T3836.4.
The intrinsically safe equipment primarily ensures safety by controlling the electrical parameters of the device circuit and limiting the energy of the entire circuit, thereby meeting the intrinsically safe explosion-proof requirements.
Key measures include reducing voltage and current, and controlling parameters of energy storage components such as inductors and capacitors.
This requires customers to refer to the design requirements for intrinsic safety circuits in GB/T3836.1 and GB/T3836.4 during circuit design.
If the client is not familiar with this standard, significant changes will be required in the product inspection stage later on.
Customers must provide electrical schematics, PCB diagrams, circuit BOM, product assembly drawings, manuals, and company standards when applying for the safety certification.
The primary testing items for intrinsically safe equipment include structural inspection, spark ignition tests, drop tests, IP testing, temperature, dielectric strength, battery and battery pack tests, and surface resistance measurement of non-metallic material casings.
If you also have products that require ATEX certification, feel free to consult Shenzhen Zhongnuo Testing Technology Co., Ltd.!

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 or explosive areas, owners require contractors to provide relevant explosion-proof electrical installation certificates to ensure the quality and safety of the work. Therefore, holding such a certificate can significantly enhance a company's competitiveness in the explosion-proof electrical installation field and bring more business opportunities.
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're in need of applying for an explosion-proof certification, feel free to consult Shenzhen ZhongNuo Testing Technology Co., Ltd. at any time!
