1. What are Coal Safety Certification and Coal Safety Mark?

Coal Mine Safety Mark Certification (abbreviated as Coal Safety Certification, also known as MA Certification) is a mandatory certification implemented by the National Coal Mine Safety Mark Office for underground coal mine supplies. All products listed in the mining product safety certification catalog must obtain a certification certificate.

Only products that have obtained the Coal Safety Certification Certificate can be affixed with the Coal Safety MA logo. No unit or individual shall sell, purchase, or use mining products that are included in the safety sign management catalog but have not obtained safety signs.

Product manufacturing enterprises applying for safety signs need to go through several steps, including filling out the application form, initial review and qualification registration, evaluation and certification.

2. What kind of enterprises can apply for the Coal Safety MA mark?

(1) Production and assembly enterprises have fixed production sites, production equipment, inspection equipment, etc;

(2) The applied product should be within the business scope of the enterprise;

(3) Having a comprehensive and effective quality assurance system;

(4) Having relevant technical expertise;

(5) Other relevant conditions

3. What are the requirements for applying for the Coal Safety MA logo on the product?

4. Can imported products apply for the Coal Safety MA mark?

Imported products can also apply for the Coal Safety MA mark. It is divided into two types: importer application and foreign production enterprise application.

(1) Apply for the MA logo according to the batch. To apply for the MA mark for a batch of imported products, importers only need to go through the application, sampling and testing process. After the testing is completed, there is no need to go through on-site evaluation of the production enterprise. They only need to inspect the batch of products and issue the certificate directly. But this certificate is only applicable to this batch of imported products, and it has no expiration date. The advantages are fast certification and low cost.

(2) Apply for the MA mark for domestically produced products. After a series of processes including application, sample testing, on-site evaluation, and certification. It is worth noting that on-site evaluation requires going to foreign production enterprises for evaluation, and the provided materials must be in Chinese, which is relatively expensive and time-consuming.

5. How long is the validity period of the Coal Safety MA logo?

At present, the validity period of the general Coal Safety MA mark is 5 years, and re certification is required after expiration. Imported products that apply for coal safety labels according to batches do not have an expiration date and are only valid for this batch of imported products.

6. Do applicants for the MA logo need to undergo factory inspection?

need.

Unlike applying for an explosion-proof certificate, the country has strict control over coal safety markings. Applying for coal safety certification requires a factory inspection of the applying enterprise.

7. Does the Coal Safety MA Mark require annual inspection?

The national safety mark management agency shall supervise and manage enterprises that have obtained the Coal Safety MA mark every year. Usually, the company is notified one day before the annual supervision review to prepare for the review, and the requirements are relatively strict.

8. Can the same production enterprise apply for the Coal Safety MA mark only once for different product categories?

may not.

According to relevant regulations, even for the same production enterprise, different product categories must apply for the Coal Safety MA mark separately and undergo on-site evaluations separately. If the product differences are small and it is evaluated that they can be placed in the same category of products, they can be used as a series of applications for the Coal Safety MA logo.

9. What documents are required to apply for coal safety certification?

(1) Enterprise standards

(2) Product manual

(3) Product drawings (circuit diagram, PCB diagram, schematic diagram, assembly diagram, hydraulic diagram, location diagram, etc.)

(4) BOM Table

(5) Nameplates, factory certificates, etc

(5) Sample
