ATEX: what to do when interpretations differ?
On a recent project, the parties involved disagreed on whether a piece of ATEX equipment was still compliant. Here is what we learned.
The context
The request was simply to replace the cover gasket of an Ex d IIC enclosure, work we carry out as an “official workshop”. Three parties were involved: Antidéflagrant Service, the enclosure manufacturer and an ISM-ATEX inspector.
Our analysis
Based on the information provided, we considered that the condition of the enclosure’s mating face could call into question compliance with the original certification conditions.
Our approach
In line with our responsibility as a manufacturer, we asked the certificate holder for an official technical position. After review, they confirmed our reservations and recommended replacing the enclosure.
The principle to remember
When a manufacturer or a certificate holder has reservations about the integrity of ATEX equipment, all stakeholders, including the end operator, must be informed so they can make an informed decision. The aim is not controversy, but transparency, risk control and the safety of installations.
In ATEX environments, when in doubt, consulting the certificate holder and sharing their opinion is good practice. A question about your equipment?
