Shenzhen ZhongNuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal safety certification.
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, adopting a "product testing + factory audit" approach.
We must conduct testing on the applied products, as well as on-site audits and annual supervisory assessments of the manufacturing facilities producing these products, which is commonly referred to as factory auditing.
The product testing aspect requires compliance with coal safety standards, such as electrical products needing to meet explosion-proof requirements in the coal mine gas environment, as well as product performance requirements.
Factory audits primarily focus on evaluating the factory based on the ISO9001 production quality system, combined with the requirements of the Mine Products Safety Mark Implementation Rules. The Safety Mark Center is the issuing and inquiry institution 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. With a dedicated explosion-proof technology engineering team and factory audit specialists, we can assist companies in conveniently and quickly applying for coal safety certification.
Our successful case studies include lightboxes, remote controls, fiber optic temperature sensors, sensors, air compressors, smartphones, thermal imaging cameras, and patrol robots.

The coal safety certification application process includes preliminary document review and submission, product testing, and on-site evaluation.
The review of documents focuses on the timeliness and completeness of the information prepared and provided by the company, while the product testing phase considers the specific structure, complexity, and testing projects of the product.
The on-site review stage is also crucial; if an on-site review is conducted, evidence can be collected directly. If issues arise during the audit process, continuous rectification and re-audits are required, which also increases the cycle time. The normal process for coal safety certification is approximately 4-6 months.

What explosion-proof certifications are required for explosion-proof products? Which organizations are eligible for applying for explosion-proof certifications?
Currently, the certification models for explosion-proof products entering the market in China are primarily three in number.
1. Issue explosion-proof certificates for equipment used in environments with explosive gases and combustible dust in non-coal mines, requiring only product testing; upon passing, certificates are issued.
2. Conduct explosion-proof 3C certification; for products listed under the explosion-proof 3C category, product testing and factory inspections are required.
3. Coal Mine Safety Certification, for explosion-proof equipment used underground in coal mines, involving product testing and factory audit certification.
Zhenuo Inspection is an institution offering explosion-proof certification application and consultation services.
We offer a one-stop consulting service for explosion-proof certification and coal safety certification, including product explosion-proof design and modification, drawing assessment, certification acquisition, and factory audit.
