Shenzhen Zhongnuo Testing Technology Co., Ltd. is based in South China and specializes in explosion-proof certification and coal safety certification application consulting services, offering one-stop explosion-proof technology consulting services.
Why is explosion-proof certification necessary for the product?
Safety in production is a must. The product is intended for use in explosive hazardous areas, which inherently poses significant risks.
If the equipment itself is not explosion-proof and can easily spark or overheat, igniting surrounding explosive materials, that could be a major issue.
The product undergoes explosion-proof certification to ensure that the equipment can be safely used even in environments with explosive hazards.
Also, due to the inherent issues with the equipment itself, it ignited the surrounding environment. Of course, if the equipment failed to contain an explosion (i.e., it was not explosion-proof), then that's another matter.
As the user, would you opt for explosion-proof equipment or standard equipment if there's a potential explosive hazard on-site?
As a supplier, wouldn't it be more appealing when offering your products at these on-site venues if they have obtained explosion-proof certification?
If your equipment is looking to obtain explosion-proof certification and enter the explosion-proof market, hurry up and send us a private message!
ZheNuo Testing has been dedicated to the explosion-proof field for many years, well-versed in the GB/T3836 and EN/IEC60079 explosion-proof standards requirements.
Provide explosion-proof product modification and design guidance, as well as a one-stop explosion-proof technology solution with certification.

What is a safety approval certificate for explosion-proof devices? What are the requirements for applying for a safety approval certificate for explosion-proof devices?
The explosion-proof equipment primarily ensures safety by controlling the electrical parameters of the device circuit and limiting the entire circuit's energy to meet the explosion-proof requirements.
Key measures include reducing voltage and current, and controlling parameters of energy storage components such as inductors and capacitors.
The product design reference standards are GB/T3836.1 and GB/T3836.4.
Customers applying for the explosion-proof certification of safety equipment need to provide electrical schematics, block diagrams, PCB layouts, tag number diagrams, product assembly drawings, and manuals.
Company standards and related materials.
Recently handled products include temperature vibration sensors, remote transmitters, monitoring devices, Bluetooth beacons, walkie-talkies, etc.
All explosion-proof certificates are of intrinsic safety type.
If you have products that require ATEX certification for explosion-proof safety, feel free to message us!

Certification for Explosion-Proof Electrical Equipment Inspection
Regarding explosion-proof electrical testing qualifications, this typically involves two main aspects: product certification and on-site facility testing.
Product Certification:
Newly launched products must undergo relevant tests in accordance with the GB/T 3836 series standards.
(2) Upon passing the test, the product will receive an explosion-proof certification, which is an essential qualification certificate for the product to be used in flammable and explosive environments.
(3) During the product certification process, the following documents are required: product design drawings, manuals, samples, etc.
2. On-site Venue Inspection
On-site explosion-proof electrical equipment inspections are conducted in accordance with the provisions of AO3009-2007 standard.
(2) Electrical equipment in use must undergo at least one periodic explosion-proof inspection every 3 years.
(3) This inspection is primarily for the users of explosion-proof equipment, ensuring safety and compliance during operation.
