Explosion-proof certification is a crucial certification to ensure the safe operation of equipment in explosive environments. Currently, domestic explosion-proof certifications are mainly categorized into Explosion-proof 3C Certification and Explosion-proof Compliance Certificate Certification.
The Explosion-Proof 3C Certification is for a portion of explosion-proof electrical equipment included in the national mandatory product certification catalog. This certification model requires both product testing and factory evaluation to ensure that the products meet the requirements of type testing as well as the factory's production conditions.
The explosion-proof certificate is applicable to products not listed in the explosion-proof 3C certification directory. This certification model is primarily based on product testing, and as long as the product passes the test, an explosion-proof certificate can be issued. However, it is important to note that for explosion-proof electrical equipment within the explosion-proof 3C directory, opting to only handle explosion-proof certificates may expose the product to risks of market supervision.
In addition, explosion-proof certification is an important type of explosion-proof certification. The certification process includes preliminary consultation, providing certification documents for assessment, laboratory explosion-proof testing, issuing test reports, and issuing the explosion-proof qualification certificate. The certification standards follow regulations such as GB/T 3836.1-2021 and GB/T 3836.2-2021, among others.
For mining explosion-proof products, coal safety certification is required, which includes steps such as explosion-proof performance testing, performance standard testing, as well as factory audits and supervision evaluations.
