Can OEM models apply for the Coal Safety Certification? -- Shenzhen ZhongNuo Inspection 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 yet. The potential issues that may arise during actual implementation remain unknown.
Please familiarize yourself with the following requirements prior to applying for the product for your convenience in declaration:
Please first select the production address for the declared product. If the production address database does not contain the production address of the declared product, the applicant should choose to "Add New Production Address" and then complete the production address information as required.
2. When the declared product is self-produced, the applicant's legal person business license scope of business should include the declared product; when the application product is an OEM production model, the OEM production factory should be a legal entity, and its legal person business license scope of business must include the declared product.
3. When 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 authorization 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 period.

What is the difference between ATEX certification and CE certification?
CE certification is a mandatory certification in the EU market; all equipment and products entering the EU market must pass the relevant CE directive certification.
For example, there are EMC directives, LVD directives, MD directives, ATEX directives, etc.
Different products are subject to different certification directives; the ATEX directive is specifically for explosion-proof equipment and products. In essence, ATEX certification is akin to the CE certification for explosion-proof products.
Each directive has different applicable standards; for the ATEX directive, the applicable standard is the EN60079 series.
The same explosion-proof type is applicable to various standard series.
For example, EN 60079.1 is the standard for explosion-proof, EN 60079.7 is the standard for increased safety, EN 60079.11 is the standard for intrinsic safety, and so on.

What test items are required to apply for an explosion-proof certification?
Explosive-proof products must pass relevant testing requirements of the explosive-proof standards to obtain an explosive-proof certificate.
Different explosion-proof types, catering to equipment used in various explosive environments, require different explosion-proof testing items.
Many customers also want to know what testing projects are required for explosion-proof products? What specific requirements are there for the explosion-proof design of the product?
We'll first provide an example of common explosion-proof testing projects below.
For example, safety intrinsic products typically involve tests such as appearance and structure inspection, spark ignition test, dielectric strength, battery and battery pack testing, temperature rise test, transient energy test, etc.
Main test items for explosion-proof products include heat and cold resistance tests, internal ignition without propagation of explosion, shell pressure resistance, IP testing, temperature rise tests, etc.
Varying test items, tailored to different modules or components of the product, each test ensures that the product meets the explosion-proof standards and achieves the required explosion-proof performance.
If a company is designing explosion-proof products and is unaware of the explosion-proof standards requirements,
ZhongNuo Inspection can provide guidance services for explosion-proof circuit design and explosion-proof structural design, including explosion-proof standards, design key points, drawing guidance, and can also act as an agent for explosion-proof testing and certification services.
