When conducting the revision of electrical/non-electrical products installed in potentially explosive areas, zones and technologies, we establish whether the means and erection of protection for the different equipment that is installed complies with the zoning category of the respective zone, as well as the requirements of the application subgroup and temperature class determined by the substance posing a hazard, i.e. whether such might constitute an ignition source at the given premises.

Our company undertakes the initial, as well as the 3-yearly mandatory onsite revision of products installed in hazardous environments based on the applicable technical standards:

  • MSZ – i.e. Hungarian Standard) EN IEC 60079-14:2014 – Electrical installations design, selection and erection (provisioning)
  • MSZ – i.e. Hungarian Standard) EN IEC 60079-17:2014 – Electrical installations inspection and maintenance (revision)

Based on Minister of Interior Decree 54/2014 (5 Dec) BM on the National Fire Code, as well as the MSZ EN 60079-17:2014 (Hungarian) standard, the revision of products is mandatory every 3 years as a minimum.
