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 is in accordance with the product certification standards EN 60079 and ISO 80079 series.
The specific requirements depend on the product's suitability for certain explosion-proof ratings and markings.
ATEX certification is issued by various authorities, typically involving a "product testing + factory audit" approach.
Currently, only ATEX certificates issued by ECM institutions have a specified validity period, which is 5 years.
Other institutions, such as TUV, CSA, TI, and others, which issue ATEX certification, do not include an expiration date on the certificates.
These require an on-site audit of the manufacturing facilities for certified products each year.
Certification validity can be maintained upon review approval. Of course, if there are updates to standards, a certificate renewal is required.
ATEX certification, although it is a EU explosion-proof certification, can also be applied for by an agent in China.
ZhongNuo Inspection has applied for ATEX certification and maintains excellent cooperative relationships with international issuing bodies and domestic laboratories.
Familiar with certification standards and processes, and able to provide on-site factory audits. For details, please message us directly.
