What are the requirements for obtaining an explosion-proof certification for robotic products?
Now, there's a growing number of robotic products being used in explosion-proof environments. Many customers have asked, "How do robotic products obtain explosion-proof certification?"
What technical requirements? By what standards? Since the product is so large, do we need to send a sample for testing?
Robot products are often modular equipment, which tends to be larger in size. Ensuring explosion-proof capabilities is a must.
This includes whole-machine explosion-proof design, electrical component selection, and installation methods.
Battery selection and installation design, preparation of drawings, electrical connections, grounding, and other technical issues.
ZheNuo Inspection has been in the explosion-proof industry for many years, well-versed in the requirements of the GB/T 3836 series standards.
Extensive experience in obtaining evidence within the robotics product field.
We offer a one-stop explosion-proof certification service, including initial explosion-proof design modifications, drawing evaluations, component selection, installation guidance, and certification acquisition.
Products that are not convenient for shipping can also be offered on-site evaluation and testing services.
Successful certification cases include patrol robots, track-mounted robots, and positive-pressure robotic arms.
