Ex Theory Only

We specialise on Units Ex 005 of the IECEx Recognised Training Provider Programme (RTPP). This focuses on the IEC BS EN 60079-19 standard on repair, overhaul and reclamation of Ex equipment.

The aims of the course are to give delegates a thorough knowledge of how the different protection concepts and standards should be used when overhauling, repairing, or reclaiming Ex equipment suitable for each zoned area.

The Ex Theory is a two-day course that focuses on the theory behind Ex equipment.

To complete the full AEMT Ex Training, the Ex Hands-on course must be taken as part of a 4-day course. 

Course content includes: 

  • Ignition sources in flammable gases, vapours and dusts

  • Principles of Ex protection for gas and dust

  • Temperature classification and groups of apparatus

  • Certification, standards and marking

  • Requirements and procedures of ATEX, DSEAR and relevant standards such as BS EN IEC 60079-19

  • Principles of protection concepts of:

  • Ex e (Increased Safety)

  • Ex nA (Incendive sparking)

  • Mechanical protection concepts:

  • Ex h incorporating  "c" constructional safety, "k" liquid immersion

The course programmes rely upon the full involvement of the delegates in discussions and exercises.
