Where to apply for explosion-proof certification? Shenzhen Zhongnuo Inspection, Application Requirements

Shenzhen Zhongnuo Inspection & Technology Co., Ltd. is headquartered in South China and specializes in explosion-proof certification and coal mine safety certification application consulting services, offering one-stop explosion-proof technology consulting.
Division of Explosion-Proof Areas in Combustible Dust Environments -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
In explosion-proof certification, hazardous areas are divided into explosive gas environments and combustible dust environments based on the different states of substances present in the location. According to the duration of presence of hazardous substances in the location, the hazardous areas under the two different states are further divided into three zones.
For environments with combustible dust, it is 20, 21, and 22 zones.
Areas in Zone 20 with continuous or long-term presence of combustible dust, typically exceeding 1000 hours per year.
Zone 21 - Areas where combustible dust environments may occur during normal operation, typically 10-1000h/y
Zone 22 - Under normal operation, flammable dust atmospheres are not possible, nor are locations with occasional, short-term occurrences, typically less than 10 hours per year.

Is a product's explosion-proof certification the same as its explosion-proof qualification certificate?
Many customers ask when inquiring, "What's the difference between obtaining explosion-proof certification and an explosion-proof qualification certificate for a product?"
Explosion-proof certification and explosion-proof compliance certificate are two different concepts. A product that undergoes explosion-proof certification receives an explosion-proof compliance certificate upon completion.
Explosion-proof certification is the process, and the explosion-proof certificate is the result.
So the customer said the product needs to have a explosion-proof certification or explosion-proof compliance certificate.
The product must pass the explosion-proof standard tests and meet the requirements to obtain an explosion-proof certification.
Explosion-proof certifications can be categorized into different protection types, including intrinsic safety, flameproof, positive pressure, and encapsulation, among others.
ZhongNuo Inspection boasts a team of explosion-proof engineers who can provide early-stage design services for explosion-proof circuits and structures.
Assist companies in preparing the necessary drawings, technical specifications, and manuals, including enterprise standards, for explosion-proof certifications, facilitating their smooth acquisition of the explosion-proof compliance certificate.

Why do companies pursue explosion-proof certification?
Intrinsically safe certification refers to the process of determining if equipment meets explosion-proof standards, requiring type testing and issuance of relevant certificates. It primarily targets Ex equipment or Ex components.
Explosion-proof products primarily refer to explosion-proof electrical equipment: used in environments where explosions of gases or dust may occur.
Electrical products or components with explosion-proof functionality, capable of igniting surrounding explosive environments under specified conditions.
Safety of explosion-proof equipment is closely related to safe production, hence many countries implement explosion-proof certification systems for explosion-proof electrical products.
Explosion-proof products must obtain explosion-proof certification to be used in flammable and explosive hazardous areas.
#Explosion-proof Certification# is essential for ensuring the safe use 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.
To enhance market competitiveness, certified enterprises in China can obtain explosion-proof certification.

What products are eligible for obtaining the intrinsically safe explosion-proof certification? What are the requirements?
Bain is one of the many explosion-proof protection types, which limits electrical energy so that equipment can still function even if a fault occurs.
A type of explosion-proof protection that the energy produced is not sufficient to ignite the surrounding explosive environment.
Therefore, intrinsic safety requirements limit the current, voltage, capacitance, inductance, etc., of electrical equipment, making it only suitable for low-power devices.
Simultaneously, specific requirements are in place for the power supply method of intrinsically safe equipment, plastic casings, and wireless transmission.
The product application for intrinsic safety certification requires the submission of the product's schematic diagram, PCB diagram, etc.
ZhongNuo Inspection has dedicated engineers specializing in intrinsic circuit and structural design.
We offer technical consulting services for explosion-proof circuit design, drafting, and modifications. We have extensive experience in designing and obtaining certifications for intrinsic safety ia, ib, and ic levels.
