Market Access System for Explosion-Proof Products
1. Explosion-proof Certification System: Applies to all explosion-proof products, utilizing the "type testing" method.
2. CCC Certification: Applicable only to certain explosion-proof products (excluding measuring instruments and explosion-proof lighting), conducted through a "Type Testing + Factory Inspection" approach
3. Coal Safety Mark (MA): Suitable for mining products, adopting the "type inspection + factory inspection" method

What documentation is required for applying for an explosion-proof certification?
1. Product Drawings and Documents: When an enterprise applies for a防爆 certification for intrinsically safe electrical equipment, it should provide assembly drawings, circuit diagrams, printed circuit board layouts, silk-screening diagrams, component material lists, and label drawings, among others. For non-intrinsically safe electrical equipment, the technical documents submitted for inspection should include drawings that reflect the sample's explosion-proof performance (including assembly drawings and component drawings). If the overall drawing clearly indicates the product's explosion-proof parameters and structure, only the overall drawing needs to be submitted for inspection.
2. Technical Documents: Include corporate standards/technical requirements. The corporate standards/technical requirements for the product should be written in the prescribed format, and their content should not only include performance requirements of the product but also cover relevant aspects of explosion-proof: such as basic parameters, explosion-proof markings, operating environmental conditions, explosion-proof performance requirements, relevant tests for explosion-proof performance, and markings related to explosion-proof.
3. Additional Information: For products with adhesive bonding or casting, provide the model names, performance descriptions, and relevant process documents for the adhesives and casting agents. For products with plastic casings, supply the material type and corresponding performance documents. Battery-powered products require the provision of battery specifications.

For applicants, what type of explosion-proof classification and what level of explosion-proof they choose is actually the same across all authorized institutions. They are all institutions that have been certified and authorized by the state, possessing testing conditions that meet standard requirements, adhering to the same standards, and conducting the same testing. Under the same conditions, the trend is inevitable to opt for institutions offering services at more affordable prices. This is also a significant reason for the increasing popularity of emerging explosion-proof enterprises.
