How long is the validity of an IECEx certificate? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
IECEx certification certificates do not have an expiration date; their validity depends on the certification center's regular supervision to maintain.
That's what we refer to as factory annual inspections/quarterly audits, etc.

ATEX Certification vs. IECEx Certification -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
ATEX is a mandatory certification in the EU; all explosion-proof equipment circulating in the EU market must comply with the ATEX Directive 2014/34/EC to be sold.
IECEx is a voluntary certification, not mandatory. It is not recognized by the EU or North American markets, and products entering these markets require reapplying for the necessary certifications.

How long is the validity of an ATEX certificate? Where can I apply for ATEX certification?
ATEX certification is a防爆 directive under the EU's CE certification, with directive code 2014/34/EU.
Mandatory certification for explosion-proof equipment and products entering the EU market, with the product certification standards being EN 60079 and ISO 80079 series.
The specific requirements depend on the product's suitability for explosion-proof ratings and markings.
ATEX certification is issued by various bodies, typically following a "product testing + factory audit" approach.
Currently, only ATEX certificates issued by ECM agencies have a specified validity period, which is 5 years.
Other institutions, such as TÜV Rheinland, TÜV SÜD, CSA, TI, and others, issue ATEX certification without specifying an expiration date.
These require on-site audits of the manufacturing facilities for certified products annually.
Certification validity can be maintained upon passing the review. Of course, if there are updates to standards, a certificate renewal is required.
ATEX certification, although it is a European Union explosion-proof certification, can also be applied for domestically.
Zhenuo Inspection offers ATEX certification application consultation services, boasting excellent cooperative relationships with international issuing bodies and domestic laboratories.
Familiar with certification standards and procedures, and able to provide on-site factory audits. For details, please message us directly.

What are the differences and connections between the ATEX certification system,防爆认证, and IECEx? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
The ATEX and IECEx standards in Europe are almost identical in content at present.
A key standard is the EN60079 series, another key standard is IEC60079, with ATEX certification, it can be sold in the EU.
Obtaining IECEx certification allows for sales to members of the international electrical engineering community.
If a member state is both within the EU and an international电工, they can forgo the IECEx application and simply apply for ATEX.
Because ATEX falls under the CE category and is a mandatory certification, whereas IECEx is not a mandatory certification.
Additionally, similar situations exist for other IEC member states.
For example, China is also a member of IEC, but explosion-proof products in China require an application for the Chinese explosion-proof certification or coal safety certification.
Cannot be substituted with IECEx.
