What is the difference between ATEX certification and CE certification?
CE certification is a mandatory certification in the EU market; 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, with the ATEX directive specifically targeting explosion-proof equipment and products.
ATEX certification can be considered the CE certification for explosion-proof products.
Each directive has different applicable standards; for the ATEX directive, the applicable standards are the EN60079 series.
Different explosion-proof types apply to different standard series.
For example, EN 60079.1 is an explosion-proof standard, EN 60079.7 is an increased safety standard, EN 60079.11 is intrinsically safe standard, etc.

After the explosion-proof CCC certification has replaced the production license, do we still need an explosion-proof compliance certificate?
Since the issuance of the market supervision regulations regarding explosion-proof electrical products and others in July 2019
Following the announcement of the implementation requirements for mandatory product certification management after the transition from production permits,
Many companies producing explosion-proof electrical products have gained a certain understanding of the explosion-proof 3C certification system.
But, does the implementation of the explosion-proof 3C certification system replace the original explosion-proof qualification certificate?
Does the product need an explosion-proof certificate to enter the market?
What are the additional requirements for a company to produce explosion-proof electrical products?
In fact, a careful reading of this announcement reveals,
The notice only includes a portion of explosion-proof electrical products in the scope of mandatory product certification.
(For details, refer to the product catalog of the mandatory explosion-proof electrical product certification.)
A significant portion of explosion-proof products have not been included in the market yet.
Common items include pressure transmitters, combustible gas detectors, breathing valves, dust removal equipment, and mechanical products.
Extraneous explosion-proof equipment installed and used in explosive areas must strictly comply with the requirements of the GB/T3836 series explosion-proof standards.
Obtain the corresponding explosion-proof certification.

Is a product's explosion-proof certification the same as its explosion-proof qualification certificate?
Many customers ask during inquiries what the difference is between obtaining explosion-proof certification for a product and obtaining an explosion-proof qualification certificate.
Blast-proof certification and blast-proof compliance certificate are two distinct concepts. A product that undergoes blast-proof certification ultimately receives a blast-proof compliance certificate.
Ex-proof certification is the process, and the ex-proof certificate is the result.
So the customer said the product needs to be certified for explosion-proof or obtain an explosion-proof certificate.
The product must pass the explosion-proof standard tests and meet the standard requirements, obtaining an explosion-proof certification.
Ex-proof certifications can be categorized into intrinsic safety type, flameproof type, positive pressure type, and pot seal type, among other explosion-proof protection types.
ZhongNuo Testing has a team of explosion-proof engineers who can provide initial design for explosion-proof circuits and structures.
Assist companies in preparing the required drawings, technical specifications, and manuals, including enterprise standards, for explosion-proof certifications, facilitating their smooth acquisition of the explosion-proof qualification certificate.
If you require certification in this area, welcome to DM Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.!

How to apply for an explosion-proof certificate? Which units issue explosion-proof certificates?
The explosion-proof certificate is a certification for the safety of equipment used in explosive environments.
The certification standards are the GB/T 3836 series. The process for a company to apply for an explosion-proof qualification certificate is relatively simple.
Please provide the electrical schematics, assembly drawings, structural diagrams, product manuals, and corporate standards for the product.
Provide samples consistent with the drawings for explosion-proof testing. Test passes.
You can then provide the explosion-proof Testing Report and the explosion-proof compliance certificate.
Currently, the main issuing bodies for explosion-proof certifications include Nanyang CNEX, Tianjin PCEC, Shanghai NEPSI, various Coal Research Institutes, Suzhou Electric Research Institute, and others.
These institutions all have comprehensive Certificates, with the same validity.
Although the process is relatively simple, it's not easy to meet the design requirements of the GB/T 3836 series standards for the product.
If your company is new to explosion-proof product design and certification, turn to Shenzhen Zhongnuo Testing Technology Co., Ltd.
