IECEx certification employs a certification method that includes: Type Testing (Product Testing) + Factory Quality System Inspection + Post-Certification Supervision.
The entire IECEx certification process spans from providing documentation, sample preparation, product testing, factory audit, to issuance of the certificate.

Explosion-proof electrical products, also known as Ex products, must obtain explosion-proof certification before they can be used in hazardous explosive areas.
To eliminate unnecessary repetitive testing and certification of Ex products across international borders,
Promoting international trade, the guo ji Diangong Hui Explosion-Proof Electrical Products Certification Organization, abbreviated as IECEx certification system, was officially established in 1996.

ATEX Certification Application
The EU has restricted the frequency of ATEX certification to only be issued by its notified bodies to control the safety performance of explosion-proof equipment.
Currently, there were 24 notified bodies involved in the ATEX Directive.
As of May 21, 2014, 67 European institutions have obtained authorization from the EU announcement.
Commonly compared ATEX notified bodies include TÜV SÜD, TÜV NORD, TÜV Rheinland, DNV, BV, QS, DEKRA, EUROFINS, UL, CSA, ECM, etc.

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