Coal safety certification is a mandatory safety certification for equipment and products used underground in coal mines. It adopts a "product testing+factory review" approach, which involves both testing the applied products and conducting on-site inspections and annual supervision reviews of the production factories where the applied products are produced, which is commonly known as factory audits.

In terms of product testing, it is required that the product meets the requirements of coal safety standards. For example, for electrical products, the coal mine gas environment should be considered to meet the requirements of explosion-proof standards, and the product performance requirements should also be met.

The factory review is mainly based on the ISO9001 production quality system and combined with the requirements of the implementation rules for safety signs of mining products for factory review.

The National Safety Standards Center is the only coal safety certification and inquiry institution.
