When many clients consult, I purchase components and equipment with explosion-proof certificates. Does the overall equipment assembled together still need explosion-proof certification? complete machineExplosion proof certificationWhat are the requirements?
As a professional explosion-proof certification agency, Zhongnuo Testing provides a clear answer: complete machine explosion-proof certification is required
This is because even if all components are equipment with explosion-proof certificates, the connection between components still needs to consider explosion-proof requirements, such as the connection between the electrical control box and the motor, and the lighting fixtures. The cables used should be fire-resistant and flame-retardant, and should be threaded through explosion-proof flexible pipes or galvanized water pipes to prevent external impacts. In addition, the connection between components of different explosion-proof types should also be considered. For example, if there is an electrical connection between explosion-proof products and intrinsic safety products, corresponding safety barriers should be added.
What are the requirements for applying for explosion-proof certification for the entire machine? What information is required?
stayZhongnuo TestingThe process of applying for explosion-proof certification for the entire machine is very simple.
Information:
1. Copy of valid explosion-proof certificate for each component
2. BOM table (which is a list of various components to be listed)
3. Structural diagram
4. Instruction manual
5. Enterprise standard
6. Schematic diagram, etc
technological process:
Due to the large size of the overall equipment and the inconvenience of transportation for customers, Zhongnuo Testing generally conducts on-site testing and evaluation at the customer's site. Only one sample is usually needed, and the sample may be disassembled for testing on site. This on-site evidence collection method greatly shortens the customer's evidence collection time and cost!
