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 a one-stop explosion-proof technology consulting service.
What is the difference between ATEX certification and CE certification?
CE certification is a mandatory certification in the EU market, and all equipment and products entering the EU market must pass the relevant CE directive certification.
For example, there are EMC directives, LVD directives, MD directives, ATEX directives, etc.
Different products require different certification directives; the ATEX directive is specifically for explosion-proof equipment and products. In essence, ATEX certification can be considered the CE certification for explosion-proof products.
Each directive has different applicable standards; the ATEX directive applies to the EN60079 series.
Different explosion-proof types apply to different standard series.
For example, EN 60079.1 is the standard for explosion-proof, EN 60079.7 is the standard for increased safety, EN 60079.11 is the standard for intrinsic safety, and so on.

Why do companies need explosion-proof certification?
Intrinsically safe certification refers to the process of verifying that equipment meets explosion-proof standards, requiring type testing and the issuance of relevant certificates of compliance. It primarily targets 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 function, 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 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.
Certification for explosion-proof can boost product exports, further enhancing the credibility and reliability of the company and its products, and increasing market competitiveness.
Qualified companies can obtain explosion-proof certification domestically.

The cost of obtaining explosion-proof certification at Shenzhen Zhongnuo Testing Technology Co., Ltd. is related to the following aspects:
1. Do you need an explosion-proof certificate or an explosion-proof 3C certification? For the 3C certification, a factory audit is required, which includes the audit fee, travel expenses for the auditor, as well as the application fee and certificate fee for the 3C certificate.
2. Related to explosion-proof markings. Different explosion-proof markings have different explosion-proof items, and the cost naturally varies.
3. Domestic explosion-proof certification or international explosion-proof certification? The same explosion-proof marking, ATEX/IECEx certification is much more expensive than the domestic explosion-proof certificate, and it also requires factory audit. North American explosion-proof certification is even more costly, over $100,000+
4. Do you need to retest? Some customers' products have never been designed for explosion-proof, and they still need to go through rectification, which adds to the cost. If the product includes batteries, battery testing is also an additional expense, especially for those batteries that keep failing the tests.
5. Needed or not. Labs are often booked up, and there's often a waiting list. If needed, there will be a fee involved.

IECEx Certification
IECEx is a certification system for explosion-proof electrical products promoted by the International Electrotechnical Commission (IEC).
The purpose is to eliminate discrepancies in equipment and services used in explosive environments, promoting international trade.
Maintain the level of equipment safety requirements. The current explosion-proof standard is IEC 60079.
IECEx certification has now become a route to obtain international safety certification for products used in all hazardous areas.
Currently available in many countries around the world (including Australia, New Zealand, Brazil, Canada, China, Japan, South Korea, Malaysia, Singapore, South Africa, and the United States, etc.).
The IECEx-certified certificates will be automatically uploaded to the IECEx website, where manufacturers and end-users can locate the relevant documents.
