Shenzhen ZhongNuo Testing Technology Co., Ltd. is based in South China and specializes in explosion-proof certification and coal safety certification application consulting services, offering one-stop explosion-proof technology consulting services.
Does the explosion-proof certification include the explosion-proof 3C certification?
Currently, in China, explosion-proof certifications are divided into Explosion-Proof 3C Certification and Explosion-Proof Compliance Certificate.
The explosion-proof certificate and explosion-proof 3C certification are for different types of explosion-proof products, each belonging to a distinct certification model.
As of October 1, 2009, a portion of explosion-proof electrical equipment was included in the CCC certification catalog, which is a mandatory product certification.
Products within the catalog undergo防爆3C certification, adopting the "Product Testing + Factory Audit" model.
Both product type tests and factory site audits are required.
Ex-proof certificate is applicable to products outside the Ex-proof 3C catalog. The certification model is Product Testing; upon successful completion of Product Testing, an Ex-proof certificate can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for explosion-proof certifications, but there's a risk of being penalized by market supervision. This should be considered by the customer themselves. When inquiring, the customer should first confirm the type of product and then decide on the certification model. If you're unsure whether the product is within the explosion-proof 3C catalog, feel free to send a private message to Shenzhen ZhongNuo Testing Technology Co., Ltd., and we'll assess and confirm for you!

Domestic Explosion-Proof Certification
Domestic explosion-proof certification is a compliance inspection conducted on explosion-proof products used in explosive environments, including electrical and non-electrical products.
Issue explosion-proof certificates for products that meet the GB/T3836 standard.
The domestic explosion-proof certification standards are essentially equivalent to the international IEC 60079 standard system.

Products with 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.

Why Do Companies Need Explosion Proof Certification?
Intrinsically Safe Certification refers to the process of determining that equipment meets explosion-proof standards, requiring type testing and issuance of relevant certificates of conformity, primarily targeting Ex equipment or Ex components.
Explosion-proof products generally 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, capable of igniting surrounding explosive environments under specified conditions.
Safety of explosion-proof equipment is closely related to safe production, which is why 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.
Blast-proof certification is essential for ensuring the safety of the use of blast-proof electrical products.
Blast-proof certification can boost product exports and further enhance the credibility and reputation of the company and its products, increasing market competitiveness.
Enterprises requiring certification can obtain explosion-proof certification domestically.
