Can an OEM model apply for the Coal Safety Certification? -- Shenzhen ZhongNuo Inspection & Technology Co., Ltd.
This year, the Anbang Standard Center has gradually expanded the scope of applicants to include OEM production model companies, incorporating them into 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 at the moment. What kind of issues may arise during implementation remains a question mark.
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 for the declared product, the applicant should choose "Add New Production Address" and then complete the production address information as required.
2. When the declared product is self-produced, the scope of business in the applicant's legal person business license should include the declared product; when the application product is produced under the OEM model, the OEM production factory should be a legal entity, and the scope of business in its legal person business license must include the declared product.
3. When the production address is rented, 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 sign 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 commission 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.

How do I apply for another Mine Safety Certification with the existing Coal Safety Certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
If the product has already been certified with the Coal Safety Certification, a new Mine Safety Certification can be applied for using the original Certificate and Report.
Need to go through one more application process, but both time and cost will be significantly reduced. So, if you already have the Mine Safety Certification, how do you apply for the Coal Safety Certification?
If the product has already been certified with the Mine Safety Certification and requires a Coal Safety Certification, it must be re-applied for as a new product.

What is the difference between ATEX certification and CE certification?
CE certification is a mandatory certification in the EU market, and all equipment and products entering the EU market must pass the relevant CE directive certification.
For instance, there are EMC directives, LVD directives, MD directives, ATEX directives, etc.
Different products are subject to various certification directives, with the ATEX directive specifically targeting explosion-proof equipment and products. In essence, ATEX certification can be considered the CE certification for explosion-proof products.
Each directive has different applicable standards; for the ATEX directive, the applicable standard is the EN60079 series.
Same explosion-proof type is applicable to various standard series.
For instance, 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's the difference between corrosion protection grade, protection grade, and explosion-proof certification grade?
Many corporate clients are often in the dark about the required corrosion resistance, protection, and explosion-proof certification levels for their products.
Due to the one-character difference in names, and both referring to a certain grade of the product, they are similar yet distinct. So, what are the differences between them?
Corrosion prevention involves measures taken to protect metal items prone to rusting, aiming to extend their lifespan. Typically, methods such as physical, chemical, and electrochemical corrosion prevention are employed. There are five common levels: indoor F1, F2, and outdoor WF, WF1, and WF2.
Protection grade, commonly known as IP rating, refers to the dust and water resistance level of the equipment, usually consisting of "IP" followed by two digits.
The explosion-proof grade generally refers to the equipment's explosion-proof certification level. Each electrical equipment applying for an explosion-proof certification will have a corresponding explosion-proof marking, including the type and grade of explosion-proof. The explosion-proof grade indicates the product's applicable explosion-proof area, gas/dust groups, temperature groups, and equipment protection level, etc.
Clearly, these are different concepts from different fields. For more information on this topic, feel free to private message Shenzhen ZhongNuo Inspection Technology Co., Ltd. anytime!
