The specific documents and materials required for applying for explosion-proof certification vary depending on the type of explosion-proof certification and the product itself. Below is a list of common documents for your reference:
1. Technical Drawings
Schematic diagrams: Illustrate the electrical connections and operating principles of the product.
Structure drawings: Describe the physical structure and assembly methods of the product.
PCB drawings: Provide the layout and wiring information of the printed circuit board.
Intrinsic safety parameters (if applicable): For intrinsically safe explosion-proof equipment, submit relevant intrinsic safety parameters and calculation basis.
Battery specification sheets (if applicable): Offer detailed information such as the type, capacity, and voltage of the battery.
SRRC certificates for wireless transmission modules or wireless transmission power test reports (if applicable): For products with wireless transmission functions, submit the corresponding radio transmission certification certificates or test reports.
Potting process documents (if applicable)
Copies of explosion-proof certificates for electrical components (if applicable)
Others: For example, specification sheets of electrical components, material composition reports, etc.
2. Product Manuals and Enterprise Standards
Product manual: Detailedly describe the functions, usage methods, precautions, etc., of the product.
Enterprise standards: If the product adopts enterprise standards, submit the relevant enterprise standard documents.
In addition, different types of explosion-proof certifications (such as complete machine explosion-proof certification, intrinsic safety explosion-proof certification, etc.) may require additional specific materials. Therefore, when preparing the materials, it is recommended that you first confirm the type of explosion-proof certification required and consult professional explosion-proof testing institutions, such as STS to obtain a more detailed and accurate list of materials.
