How to obtain certification for explosion-proof electrical products not listed in the CCC explosion-proof product catalog?
ZhongNuo Inspection: Currently, the product catalog only includes most explosion-proof electrical equipment, but there are still some explosion-proof equipment, such as large-scale system equipment and explosion-proof lighting, which are not included in the catalog. They still need to apply for the original explosion-proof certification and obtain the certification before they can be used in explosive hazard areas.

What requirements do applicants need to meet after converting explosion-proof electrical products to mandatory product certification (CCC certification)?
ZhongNuo Inspection: Mandatory Product Certification, also known as CCC Certification, involves a certification model that includes Type Testing + Initial Factory Inspection + Post-Certification Supervision. In simpler terms, it requires a factory audit. The applicant must have the capability for production/inspection/shipping (or OEM/ODM).

What test items are required to apply for an explosion-proof certificate?
Explosive-proof products require passing relevant testing requirements of the explosive-proof standards to obtain an explosive-proof certificate.
Different explosion-proof types, catering to equipment used in various explosive environments, require different explosion-proof testing items.
Many customers also want to know which test items are required for explosion-proof products? What are the specific requirements for the explosion-proof design of the product?
Below, we'll provide examples of common explosion-proof testing items.
For instance, with intrinsic safety products, general test items typically include appearance and structure inspection, spark ignition tests, dielectric strength, battery and battery pack testing, temperature rise tests, transient energy tests, etc.
Main test items for explosion-proof products include heat and cold resistance tests, internal ignition without propagation of explosion, shell pressure resistance, IP testing, temperature rise tests, etc.
Different testing items, tailored to various modules or components of the product.
Each test item ensures the product meets explosion-proof standards and achieves the required explosion-proof performance.
If a company is designing explosion-proof products without understanding the explosion-proof standards requirements,
ZhongNuo Inspection can provide guidance services for explosion-proof circuit design and explosion-proof structural design.
Including explosion-proof standards, design key points, drawing guidance, and can also act as an agent for explosion-proof testing and certification services.
