For repairs, overhauls, scheduled preventative maintenance, and other service-level procedures.
IEC Ex Certified Service Facility Required
The oven must be serviced by an IEC Ex-certified facility or by IEC Ex-certified technicians from
such a facility deemed competent to work with the explosion protection types used in this oven (Ex
ia, pzc, mc).
• The oven user (the owner or designated responsible individual) is obligated under IEC
60079-19 4.3.4 to verify that the service facility chosen to work on the oven demonstrates
compliance with IEC 60079-19.
• Your safety jurisdictions’ health and safety laws or ordinances may also require this
compliance.
Explosion Protection Systems Compromised
•
Failure to have the oven serviced by an IEC Ex competent facility can lead to the oven
explosion protection systems being compromised, endangering your employees and facility.
Loss of Ex Marks and Safety Certification
• The oven Ex marking and Ex explosion certifications are no longer valid if the oven is
serviced by a non-certified facility. This may void or adversely impact insurance policies
and regulatory compliance standing.
•
An oven that loses its Ex certification must be re-certified by an IEC Ex qualified NRTL or
accredited or notified body.
