What products can apply for the intrinsically safe explosion-proof certification? What are the requirements?
"Ben-Air is one type of explosion-proof protection, which limits electrical energy so that equipment remains safe even in the event of a malfunction."
A type of explosion-proof protection that the energy produced is not sufficient to ignite the surrounding explosive environment.
Therefore, intrinsic safety requirements for electrical equipment include limitations on current, voltage, capacitance, inductance, etc., making them suitable only for low-power devices.
Additionally, there are specific requirements for the power supply method of intrinsically safe equipment, plastic enclosures, and wireless transmission.
The product application for intrinsic safety certification requires the submission of the product's schematic, PCB diagram, etc.
ZhongNuo Inspection has dedicated engineers specializing in intrinsic safety circuit and structural design.
We offer technical consultation services for explosion-proof circuit design, drafting, and modification. We have extensive experience in designing and obtaining certifications for intrinsic safety levels ia, ib, and ic.
If you require certifications in this field, welcome to DM Shenzhen ZhongNuo Testing Technology Co., Ltd.!

What is the relationship between the explosion-proof certificate and the explosion-proof CCC certification?
Which certification is required for a company's explosion-proof products to enter the market? What are the requirements for the applying company, etc.? These are many of the current dilemmas faced by enterprises.
Below, ZhongNuo Inspection simplifies it for everyone's understanding.
Firstly, explosion-proof certificates and the explosion-proof CCC certification are both certification requirements for explosion-proof equipment.
Whether to apply for a防爆 certificate or防爆CCC certification largely depends on the product category.
Put simply, it's to check if your product is listed in the防爆CCC certification product catalog.
Yes, obtain the explosion-proof CCC certification; no, obtain the explosion-proof compliance certificate.
