Overview

The SIST EN 60079-1:2015/A11:2024 standard addresses the protection of electrical equipment intended for use in explosive atmospheres by means of flameproof enclosures ("d"). This amendment aligns the European Standard with the International Electrotechnical Commission’s interpretation sheet IEC 60079-1:2014/ISH1:2020, ensuring harmonized requirements across Europe for equipment safety in hazardous environments. Issued by CLC and approved by CENELEC in January 2024, it clarifies technical provisions around flameproof enclosure designs, particularly focusing on threaded entries.

Key Topics

• Flameproof Enclosures "d": Specifies design and testing requirements for enclosures that contain any explosion within and prevent transmission to external atmospheres.
• Threaded Entries Restriction: Introduces a major technical change that limits threaded entries on flameproof enclosures exclusively to metric and NPT (National Pipe Thread) forms. This amendment aims to reduce mismatches and improve the integrity of enclosure entries.
• Thread Adapters and Blanking Elements:
  • Thread adapters fitted as factory-assembled parts may use other thread forms beyond metric and NPT.
  • Blanking elements can be installed in thread adapters that are factory-fitted and assessed as part of the flameproof enclosure.
• Marking Requirements: The amendment mandates clear identification of the thread type and size for threaded entries, including those pertaining to thread adapters assembled on the enclosure for field wiring connections.
• Alignment with IEC Standards: Ensures consistency with IEC 60079-1:2014/ISH1:2020, endorsed by CENELEC without modification, reinforcing a unified international approach.

Applications

SIST EN 60079-1:2015/A11:2024 is particularly relevant for industries operating in hazardous locations where explosive atmospheres may be present, such as:

• Oil and Gas: Equipment used in refineries, drilling sites, and petrochemical plants requiring flameproof enclosures.
• Chemical Processing: Ensuring electrical apparatus can safely operate near volatile substances.
• Mining: Protection of electrical systems in underground and surface mines with potential explosive gases or dust.
• Pharmaceuticals & Manufacturing: Facilities handling flammable powders or vapors benefiting from standardized enclosure protection.

By adhering to this standard, manufacturers can ensure equipment safety compliance, reduce the risk of explosions, and meet European regulatory requirements for devices used in explosive atmospheres.

Related Standards

• IEC 60079-1:2014 – The international standard for equipment protection by flameproof enclosures.
• IEC 60079 Series – Comprehensive safety standards for equipment in explosive atmospheres, including intrinsic safety, increased safety, and more.
• EN 60079-0 – General requirements for electrical apparatus used in explosive atmospheres.
• EN 60079-7 – Equipment protection by increased safety "e", complementing flameproof enclosure protections.

Compliance with SIST EN 60079-1:2015/A11:2024 supports harmonization with these standards, facilitating the certification process and international market access.
