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.
IECEx Certification
IECEx is a certification system for explosion-proof electrical products promoted by the International Electrotechnical Commission (IEC).
The aim is to eliminate discrepancies in equipment and services used in explosive environments, and to promote international trade.
Maintain the level of equipment safety requirements. The current explosion-proof standard is IEC60079.
IECEx certification has now become a route for products used in all hazardous areas to obtain international safety certification.
Currently available in many countries worldwide (Australia, New Zealand, Brazil, Canada, China, Japan, South Korea, Malaysia, Singapore, South Africa, the United States, etc.).
IECEx-certified certificates will be automatically uploaded to the IECEx website, where manufacturers and end-users can locate the relevant documents.

How to check the explosion-proof certificate
Buyers and selectors of explosion-proof electrical equipment will always choose manufacturers or distributors with explosion-proof certification.
So, as a consumer, how can users verify the authenticity and validity of the explosion-proof certification?
Currently, there are a dozen or so authorized issuing bodies for domestic explosion-proof certification.
There is no unified search platform for explosion-proof certificates issued by various certification bodies.
Explosion-proof certificates issued by various institutions can only be checked on their respective websites.
Of course, each issuing organization can verify the authenticity of certificates by phone.
If the query certificate is genuine, the main parameters and validity period will be displayed below.
If so, of course, it couldn't be found.
It's worth noting that due to each issuing authority manually uploading their certification documents, there may be a certain degree of lag.
That is to say, the newly acquired certificate may not be searchable on their website, so it's necessary to directly consult the issuing authority.

What test items are required to apply for an explosion-proof certificate?
To obtain an explosion-proof certificate, explosion-proof products must pass the relevant test requirements of the explosion-proof standards.
Different explosion-proof types, catering to equipment used in various explosive environments, require different explosion-proof testing items.
Many customers also want to know what testing items are required for explosion-proof products? What specific requirements are there for the explosion-proof design of the product?
Next, let's take a look at some common explosion-proof testing items.
For instance, with intrinsically safe products, general test items typically include appearance and structure inspection, spark ignition test, dielectric strength, battery and battery pack testing, temperature rise test, transient energy test, and more.
Main test items for explosion-proof products include heat and cold resistance tests, internal ignition without propagation of explosion, shell pressure resistance, IP testing, temperature rise tests, etc.
Different testing items, tailored to various modules or components of the product, each item ensures that the product meets the explosion-proof standards and fulfills the explosion-proof performance requirements.
If a company is designing explosion-proof products and is unaware of the explosion-proof standards requirements,
ZhongNuo Inspection offers guidance services for explosion-proof circuit design and explosion-proof structural design, including explosion-proof standards, design essentials, and drawing guidance.
We can also offer consulting services for explosion-proof testing and certification application.

The cost of obtaining explosion-proof certification through Shenzhen Zhongnuo Testing Technology Co., Ltd. is related to the following aspects:
1. Should we obtain a防爆 certification or the防爆 3C certification? For the防爆 3C certification, a factory audit is required, which includes the audit fee, travel expenses for the auditor, the applying fee for the 3C certificate, and the Certificate fee, etc.
2. Related to explosion-proof markings. Different explosion-proof markings denote different explosion-proof items, and naturally, the costs vary accordingly.
3. Domestic explosion-proof certification or international explosion-proof certification? The same explosion-proof mark, ATEX/IECEx certification is much more expensive than the domestic explosion-proof qualification certificate, and it also requires factory audits. North American explosion-proof certification is even more costly, over 100,000+
4. Do you need to be retested? Some customers' products have never been designed for explosion-proof, and they require rectification upon arrival, which adds to the cost. If the product includes batteries, battery testing is also an additional expense, especially for those that frequently fail testing.
5. Needed or Not. Labs are often booked solid, and there's often a waiting list. If required, there will be a fee involved.
