Which products can apply for the intrinsically safe explosion-proof certificate? What are the requirements?
Benign is one type of explosion-proof protection, which limits electrical energy so that the equipment can still operate even if a fault occurs.
A防爆型式, where the energy produced is insufficient to ignite an explosive environment around.
Therefore, intrinsic safety requirements impose limitations on electrical equipment's current, voltage, capacitance, inductance, etc., making it suitable only for low-power devices.
Simultaneously, specific requirements are imposed on the power supply method for explosion-proof equipment, plastic casings, and wireless transmitters.
To apply for intrinsic safety certification, you need to provide the product's schematic, PCB diagram, and so on.
ZhongNuo Inspection has dedicated engineers specializing in intrinsically safe circuit and structural design.
We offer technical consulting services for explosion-proof circuit design, drafting, and modifications. We have extensive experience in designing and obtaining certifications for intrinsically safe ia, ib, and ic explosion-proof classifications.

Do you have a product catalog for explosion-proof electrical equipment that has been converted to mandatory product certification (CCC certification)?
ZhongNuo Inspection: Yes. The market has transitioned from production license to mandatory product certification for explosion-proof electrical equipment at the same time as its release.
We have also issued a notice regarding the conversion of explosion-proof electrical products from production license to mandatory certification scope.
Products within the product catalog must be produced, sold, or engaged in other business activities during the transition period with a valid production license or CCC certification.
After the transitional period, only products with valid CCC certification can be manufactured, sold, or engaged in other business activities.
