Explosion-proof Certification Categories -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
Blastproof certification is the process of verifying that equipment meets the requirements of blastproof standards, type testing, and routine tests applicable to it, and issuing the relevant certificates of compliance. Certificates can be issued for Ex equipment or Ex components.
Different regions have varying certification standards and systems for explosion-proof electrical products. Currently, explosion-proof certifications internationally can be categorized into domestic explosion-proof certification, ATEX certification, IECEx certification, and North American explosion-proof certification.

How to Apply for Explosion-Proof Certification for a Company:
1. Self-Application: The company applies to the certification body independently, prepares relevant documents, assists in debugging the sample machine, and modifies the parts that are not in accordance with the regulations. This process takes a relatively longer period, involves higher comprehensive costs, and requires more time and effort.
2. Agent Application: Refers to the entire consultation and application process with Shenzhen ZhongNuo Testing Technology Co., Ltd., including material modifications, prototype debugging, and progress coordination, which are handled by the consulting agency, ensuring a good progress guarantee. Fast certification, controllable overall costs, time and effort-saving.

Explosion-proof product categories with certification:
The new implementation measures are divided into 17 product units:
Explosion-proof motors: center height ≤ 160mm, or rated power ≤ 15kW; Explosion-proof motors: 160mm < center height ≤ 280mm or 15kW < rated power ≤ 100kW; Explosion-proof motors: 280mm < center height ≤ 500mm or 100kW < rated power ≤ 500kW; Explosion-proof motors: center height > 500mm or rated power > 500kW.

What are the requirements for applying for an explosion-proof certification for gas detectors?
Gas detectors are a common type of explosion-proof product, with common types including intrinsically safe, flameproof, and both flameproof and intrinsically safe.
The type of explosion-proof design to be adopted depends on the product's structure, installation method, and usage location, etc.
Portable and handheld models are recommended to obtain intrinsic safety explosion-proof certificates; they are relatively lightweight.
Additionally, if used in Zone 0, the gas detector can only be intrinsically safe IA explosion-proof level.
For intrinsically safe models, consider intrinsic circuit design, shell material, battery temperature rise tests, etc.
Fixed installations can be made explosion-proof. Explosion-proof products tend to be heavy, primarily achieving explosion prevention through the use of explosion-proof casings.
Even if internal components produce sparks, the explosion can be blocked from spreading due to the explosion-proof housing's function.
On the other hand, the housing can also prevent external explosion sparks from entering the interior of the equipment.
Of course, some gas detectors can't simply achieve explosion-proof performance with intrinsic safety or explosion-proof design.
At this point, consider explosion-proof and intrinsically safe composite types.
ZhongNuo Inspection has already obtained domestic and international explosion-proof certifications for gas detectors, alarms, transmitters, and other instruments and meters for our clients.
