Shenzhen ZhongNuo Inspection Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal mine safety certification.
Which products can apply for the intrinsically safe explosion-proof certification? What are the requirements?
Bain is one of the many explosion-proof protection types, which limits electrical energy so that the equipment can still function even if a fault occurs.
A type of explosion-proof protection where the generated energy is insufficient to ignite the surrounding explosive environment.
Therefore, intrinsic safety requirements impose limitations on the current, voltage, capacitance, inductance, and other parameters of electrical equipment.
Suitable only for low-power equipment. Additionally, there are clear requirements for the power supply method of intrinsically safe equipment, plastic casings, and wireless transmitters.
The product application for intrinsic safety certification requires the submission of the product's schematic diagram, PCB layout, and other relevant documents.
ZhongNuo Inspection has dedicated engineers specializing in intrinsically safe circuit and structural design, offering technical consulting services for explosion-proof circuit design, drafting, and modifications.
We have extensive design and certification experience for intrinsic safety IA, IB, and IC ratings.
If you require certification in this area, welcome to DM Shenzhen Zhongnuo Testing Technology Co., Ltd.!

The domestic coal safety certification system is still quite strict. It combines type testing with factory production system inspection.
To ensure that the applicant company is capable of ensuring product production and capability. Even after obtaining the coal safety certification,
The company must also undergo annual supervision and evaluation by the Safety Standard Center.

Can OEM models apply for the Coal Mine Safety Certification? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
This year, the Anbang Standard Center has gradually expanded the scope of applicant companies, including OEM production mode enterprises in the Anbang application range. This means that companies previously operating under the OEM production model can now apply for the Coal Safety Certification themselves. However, there is no actual implementation as of now. The potential issues that may arise during actual implementation remain unknown.
Please familiarize yourself with the following requirements prior to product application for your convenience.
Please first select the production location for the declared product. If there is no production location for the declared product in the production location database, the applicant should choose "Add New Production Location" and then complete the production location information as required.
2. When the declared product is self-manufactured, the business scope of the applicant's corporate legal person business license should include the declared product; when the application product is in the OEM production model, the OEM manufacturer should be a legal entity, and its corporate legal person business license business scope must include the declared product.
3. If the production address is leased, the applicant should pay attention to the validity period of the lease agreement. If the declaration time is less than five years from the termination date of the lease agreement, the validity period of the safety mark will be affected by the validity period of the lease agreement.
4. For OEM-manufactured products, applicants should pay attention to the validity period of the OEM agency agreement. If the declaration time is less than five years from the termination date of the OEM contract, the validity period of the safety mark will be affected by the contract's validity.
