Why Do Companies Need Explosion-Proof Certification?
Intrinsically Safe Certification refers to the process of determining if equipment meets explosion-proof standards, requiring type tests and the issuance of relevant certificates. It primarily targets Ex equipment or Ex components.
Explosion-proof products mainly refer to explosion-proof electrical products: used in environments where explosions of gases or dust may occur.
Electrical products or components with explosion-proof functions that can ignite surrounding explosive environments under specified conditions.
Safety of explosion-proof equipment is closely related to safe production, hence many implement explosion-proof certification systems for explosion-proof electrical products.
Explosion-proof products must obtain explosion-proof certification before they can be used in flammable and explosive hazardous areas.
#Explosion-proof Certification# is essential for ensuring the safety of explosion-proof electrical products.
Blast-proof certification can boost product exports and further enhance the credibility and reputation of the company and its products.
Enhance market competitiveness by obtaining explosion-proof certification for enterprises domestically.

Products under explosion-proof certification:
The new implementation details are divided into 17 product units:
Explosion-proof Motors: Center height ≤ 160mm, or rated power ≤ 15kW; Explosion-proof Motors: 160mm < center height ≤ 280mm or 15kW < rated power ≤ 100kW; Explosion-proof Motors: 280mm < center height ≤ 500mm or 100kW < rated power ≤ 500kW; Explosion-proof Motors: Center height > 500mm or rated power > 500kW.

What is the relationship between the explosion-proof certificate and the explosion-proof CCC certification?
The explosion-proof certificate and the explosion-proof 3C certification are for different types of explosion-proof products.
Explosion-proof 3C Certification is applicable to products listed in the explosion-proof 3C catalog. There is a dedicated product catalog for explosion-proof 3C.
Products within the catalog are subject to explosion-proof 3C certification, adopting the "Product Testing + Factory Audit" model.
Both type tests of the product and on-site factory evaluations must be conducted.
Certificate of Compliance for Explosion-Proof for products not listed in the Explosion-Proof 3C Catalog.
The certification model is product testing; once the testing passes, a frequent explosion-proof certification can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for explosion-proof certificates alone, but there is a risk of being penalized by market supervision.
This is for the customer to consider.

What test items are required to apply for an explosion-proof certification?
Explosive-proof products require passing relevant testing requirements of the explosive-proof standards to obtain an explosive-proof certification.
Different explosion-proof types, catering to equipment used in various explosive environments, require different explosion-proof testing items.
Many clients also want to know what testing projects are required for explosion-proof products? What specific requirements are there for the explosion-proof design of the product?
Below, Zhenuo Testing will exemplify some common explosion-proof testing projects.
For instance, safety-intrinsic products typically include testing items such as appearance and structure inspection, spark ignition test, dielectric strength, battery and battery pack testing, temperature rise test, transient energy test, etc.
Flameproof products mainly undergo tests such as heat and cold resistance, internal ignition without propagation of flame, shell pressure resistance, IP testing, temperature rise testing, etc.
Different test items, tailored to various modules or components of the product, each test item ensures that the product meets the explosion-proof standards and fulfills the explosion-proof performance requirements.
If a company is designing explosion-proof products and is not aware of 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, etc.
We also offer agency services for explosion-proof testing and certification.
