How IEC 60079-14 Redefines Flameproof Cable and Cable Gland Selection in Hazardous Areas

The sixth edition of IEC 60079-14:2024 introduces a fundamental change in how cables and cable entry devices are selected for use in hazardous areas. What was previously a largely component-based and prescriptive process has evolved into a system-based, application-dependent assessment requiring deeper technical understanding, documented justification, and demonstrable personnel competence.

The latest edition of IEC 60079-14:2024, published in August 2024, brings into force new requirements for cable gland products, particularly for flameproof (Ex d) applications, designed for use in explosive environments. To help manufacturers understand the changes and how to design for compliance, this whitepaper explores the updates in Part 14, and what they should consider to ensure product's future and continued compliance.   

The whitepaper will cover:    

• Background: Cable and Gland Selection in Previous Editions 04 
• Drivers for Change in IEC 60079-14:2024 06 
• A Structural Shift: From Individual to System Assessment 06 
• Key Technical Changes Affecting Cable and Cable Gland Selection 08 
• Impact on Industry Stakeholders 10 
• Transitional Considerations & Global Adoption 11 

 

Abstract 

This whitepaper explores how IEC 60079‑14:2024 fundamentally redefines the selection of cables and cable entry devices for flameproof (Ex d) installations in hazardous areas. Moving from prescriptive, component‑based rules to a system‑level, evidence‑driven approach, the new edition introduces a rigorous flowchart, normative cable testing, and a strong emphasis on competence and documented justification. Readers will gain clarity on key technical changes, the implications for designers, manufacturers, installers, and inspectors, and the practical steps required to ensure safe, compliant, and future‑ready explosion‑protected installations. 

 

Excerpt 

The publication of IEC 60079-14:2024 represents the culmination of more than a decade of technical debate and standards development following the shortcomings identified in the 2013 edition. While the resulting methodology does not fully satisfy all technical viewpoints, it reflects a deliberate and considered compromise intended to balance safety, practicality, and global applicability.  

The testing requirements and selection criteria are based on empirical data collated into IEC document “IEC SC31J-SD-001:Ed1/2021-03 - Background to flameproof cable gland requirements in IEC 60079-14” A review of the history and technical factors associated with cable gland selection for flameproof (Ex “d”) enclosures as background to the selection criteria in IEC 60079-14”
