Marking of repair vs Ex

In case you get a repaired Ex installation back to your premises you might face the challenges of compliance – pls see the possible cases:
In accordance with certificate documentation and/or manufacturer’s specification
This mark is to be used only when the repair or reclamation is in accordance with this standard and the repairer has sufficient evidence of full compliance with the certificate documentation and/or manufacturer’s specification.

In accordance with the type of protection standards but not the certificate documentation
This mark is to be used when either
a) the equipment is changed during repair or reclamation so that it still complies with the restrictions imposed by this standard and the explosion-protection standards to which it was manufactured, but repairer has insufficient evidence of full compliance with the certificate documentation; or
b) the standards to which the equipment was manufactured are not known, but the requirements of this standard and the current edition of the relevant explosion-protection standards have been applied but repairer has insufficient evidence of full compliance with the certificate documentation. An assessment, by a person competent in assessing explosion-protected equipment has been conducted to verify compliance with the relevant level of safety prior to release of the equipment by the repairer.
In these situations the certification labels should not be removed.

NOTE These marking are required for the benefit of subsequent repairers and the only difference between the markings is the method of compliance.
Other situations
Equipment which, after repair or reclamation, does not conform to any of both cases above should have its original manufacturer’s label removed or altered to give a clear indication that the equipment is not in compliance with the certificate documentation until a supplementary certificate is obtained to cover the repair or overhaul.
If the equipment is returned to its owner before such a supplementary certificate is obtained, the record should indicate that the equipment is not in serviceable condition and is not to be used in an explosive atmosphere.
Question:

1. Have you ever met a similar marking on your repaired Ex installation?

If the answer is not, then you face trouble! The device might not be Ex anymore.
Keep up good work!
