This certificate is issued under the China Mining Product Safety Mark Certification System (CMAC), administered by the National Center for Safety Mark Certification of Mining Products (AQB).

It certifies that the product “Mining Wet Dust Suppression Device (KCS-300D)” complies with the relevant Chinese mining safety technical standards and CMAC certification requirements for underground coal mine applications.

The certification covers the full conformity assessment process, including technical documentation review, type testing, factory inspection, and post-certification supervision, ensuring that the equipment meets strict requirements for safe operation in coal mine environments, particularly in dust suppression and occupational health protection.

In international compliance positioning, CMAC certification is functionally comparable to global mining safety and hazardous environment regulatory systems such as:

MSHA (Mine Safety and Health Administration, USA) approvals for mining equipment safety compliance

ATEX Directive (EU 2014/34/EU) for equipment used in explosive atmospheres (where applicable to system integration environments)

IECEx system for explosion-hazardous area equipment certification framework

However, CMAC is specifically focused on coal mine safety and occupational hazard control in China, especially for underground dust management, air quality improvement, and safe operation in high-dust mining environments.

Products certified under CMAC are officially approved for use in coal mining operations in China, ensuring compliance with national safety regulations and industrial protection standards.
