ATEX certification is applicable to which regions? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
ATEX is the abbreviation of "Atmospheres Explosibles" in French, meaning "Explosive Atmosphere."
It is a防爆 directive within the EU's CE certification.
As of July 1, 2003, all equipment and protective systems entering the EU market and used in explosive environments.
The product must comply with the ATEX (94/9/EC) Directive, which is a mandatory certification for the EU market. The directive has been updated to 2014/EU/34.
ATEX certification is a mandatory certification for explosion-proof electrical products in the European market.
The scope of equipment applicable to this directive includes fixed offshore platforms, petrochemical plants, flour mills, and other locations with potential explosive environments. An estimated 3 billion euros worth of such equipment is procured in the European market annually.
Products with ATEX certification enjoy greater customer trust and market recognition in the EU, enhancing the company's credibility and the international competitiveness of the products.

What are the applications for IECEx certification? -- Shenzhen ZN Testing Technology Co., Ltd.
IECEx is an international certification, and there are several ExCB and ExTL in China as well.
It's widely known that the process for a company to apply for IECEx certification is rather complex, and the standard certification cycle takes around 5-6 months.
During the certification process, it is also necessary to provide and modify various certification documents and technical files. Many businesses have expressed that they cannot cope with this.
So, there are also numerous IECEx-certified agents on the market, such as Shenzhen Zhongnuo Inspection Technology Co., Ltd.
We are familiar with the product standards (IEC 60079 series) and system standards (ISO 80079-34) of the IECEx certification.
Familiar with the entire range, technical documents for certification samples provided.
We can also assist with initial product explosion-proof design and rectification, as well as provide explosion-proof system training for corporate clients.

What does the explosion-proof marking Ex db ib IIC T4 Gb mean?
An explosion-proof marking can be considered a certificate for explosion-proof equipment, through which one can understand the type of explosion-proofing adopted by the equipment.
Explosive areas and explosion-proof zones, etc.
What is an explosion-proof marking? What does an explosion-proof marking signify? How do you interpret the explosion-proof markings on explosion-proof equipment?
In response to these issues, ZN Testing provides a detailed explanation for your reference.
For example, explosion-proof marking Ex db ib IIC T4 Gb.
This is a composite explosion-proof marking.
Ex indicates explosion-proof; all explosion-proof equipment must be marked with the Ex symbol.
db ib refers to the explosion-proof protection type of the equipment, meaning it is both explosion-proof and intrinsically safe.
IIC refers to equipment suitable for explosive gas atmospheres of IIC category gases (representative and).
T4 is a temperature category, indicating that the surface temperature of the equipment does not exceed 135°C.
Gb refers to the equipment protection level, applicable to Zones 1 and 2.
Above is an example of a common explosion-proof symbol used in explosion-proof equipment for environments with explosive gases.
If the equipment is used underground in coal mines or in environments with combustible dust, the explosion-proof markings are different.
If it's an ATEX explosion-proof certification mark, it gets more complex.
