Shenzhen ZhongNuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof and coal safety certifications.
Currently, the frequent occurrence of coal safety certification is under the Safety Standardization Center. Below the Safety Standardization Center, there are various local Testing institutions.
Responsible for product testing tasks in different product fields.
Generally, when a company applies for coal safety certification, they cannot directly find a lab to conduct the testing.
Only by the testing certification issued by the Anbang Standard Center to Anbang Standard Laboratories.
In reality, the domestic coal safety certification system is rather stringent. It combines type testing with a factory production system review.
To ensure that the applicant company is capable of ensuring product production and capability.
Even after obtaining the coal safety certification, the company must still undergo an annual supervision and evaluation by the Safety Standardization Center.

Basic Process and Application Consultation Agency for Coal Safety Certification
Coal Mine Safety Certification is a mandatory safety certification for equipment and products used underground in coal mines, implemented through a "Product Testing + Factory Audit" approach.
We must conduct both product testing and on-site audits of the manufacturing facilities for the products in question, as well as annual supervisory reviews, 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, as well as product performance requirements.
Factory inspections primarily focus on evaluating the factory based on the ISO9001 production quality system and in conjunction with the requirements of the Mine Product Safety Mark Implementation Rules. The Safety Mark Center is the issuing and inquiry body for coal safety certifications.
Shenzhen ZhongNuo Inspection offers coal safety and mine safety certification application consulting services, well-versed in the entire certification process and requirements. We have a dedicated explosion-proof technology engineering team and factory audit specialists, ready to assist companies in conveniently and quickly applying for coal safety certification.
