The newly published IEC 60079-14:2024 standard brings several significant updates for those involved in the design, selection, installation, and initial inspection of electrical systems in explosive atmospheres.
Major changes include:
✅ The title now explicitly includes “Electrical installation design, selection and installation of equipment, including initial inspection” to cover all relevant areas.
✅ Terminology Changes
✅ Major restructure of the content with specific sections covering design, selection, installation, and initial inspection
✅ Requirements for simple apparatus are now aligned with IEC 60079-11.
✅ New flowchart covering flameproof cable entry devices: Considers equipment groups, cable lengths, and enclosures with volumes ≤ 2,000 cm³.
✅ Annex Updates: The previous informative Annex E has been updated to a new normative Annex C covering pressure testing of cables into flameproof enclosures.
The previous normative Annex C, tables for initial inspection, have been included in a new informative Annex O, allowing customised checklists for specific installations. A new initial inspection table covering the type of protection Ex “o” liquid immersion has also been introduced.
