What is Coal Safety Certification? How can a company apply for Coal Safety Certification?
Coal Safety Certification is a mandatory safety certification for equipment and products used in underground coal mines, which adopts a "product testing + factory audit" approach.
We must conduct tests on the products applied for, as well as on-site audits and annual supervisory reviews of the manufacturing facilities for these products, which is commonly referred to as "factory auditing."
Product testing requires compliance with coal safety standards, such as electrical products needing to meet explosion-proof requirements in coal mine gas environments, while also adhering to product performance standards.
Factory audits primarily focus on the ISO9001 production quality system, with additional requirements from the Mine Product Safety Mark Implementation Rules. Consequently, applicants must have their own production factory or OEM factory.
Note that not all products are eligible for the coal safety certification through the OEM application process.
