Overview

SIST EN 60079-7:2016/A11:2024 is an important European amendment to the standard for equipment protection by increased safety "e" in explosive atmospheres. Published by CLC (European Committee for Electrotechnical Standardization), this amendment aligns European regulations with IEC’s interpretation sheet IEC 60079-7:2015/ISH1:2016. It clarifies essential technical requirements for electrical equipment used in hazardous locations, ensuring safety and compliance.

This standard addresses equipment used in environments where explosive gases or vapors may be present and specifies how to design and manufacture electrical apparatus to prevent ignition risks by using increased safety measures-a critical factor for industries such as oil and gas, chemical processing, and mining.

Key Topics

• Equipment Protection by Increased Safety "e":
  The standard details requirements to prevent sparks, arcs, and hot surfaces in electrical devices, ensuring the equipment’s safe operation in explosive atmospheres.

• Ingress Protection (IP) Requirements:
  A key clarification focuses on terminal boxes in motors rated at 1 kV or higher. It specifies that if the motor’s interior has an ingress protection rating of IP54 or greater (per IEC 60079-0), terminal boxes opened to the interior are allowed. If IP44 or less, such use is prohibited.

• Harmonization with IEC Interpretation Sheet:
  The amendment incorporates IEC’s official interpretation to maintain consistency across international standards, preventing conflicting national applications and ensuring smooth adoption across CENELEC member countries.

• Scope of Application:
  Applies to electrical apparatus intended for use in explosive gas atmospheres, focusing particularly on machines and terminal boxes with increased safety measures.

Applications

This amendment and the EN 60079-7 standard are vital for:

• Manufacturers of Electrical Motors and Equipment:
  Producers of motors, terminal boxes, and related electrical apparatus designed for installation in explosive atmospheres must comply with these updated IP and safety requirements.

• Industrial Operators and Engineers:
  Facilities operating in hazardous environments such as petrochemical plants, refineries, and mining sites rely on this standard to select products that mitigate explosion risks.

• Certification Bodies and Inspectors:
  Standardizes requirements aid testing labs and certification agencies during product approval, ensuring equipment meets legal and safety criteria throughout Europe.

• Design and Safety Compliance Teams:
  Engineering teams benefit from clear guidance on the ingress protection levels and design constraints needed to comply with increased safety standards.

Related Standards

• IEC 60079-0:
  General requirements for electrical equipment in explosive atmospheres, including testing methodologies for IP ratings.

• IEC 60079-7:2015:
  The parent standard detailing increased safety "e" protection methods.

• IEC 60079-7:2015/ISH1:2016:
  Interpretation sheet providing clarifications incorporated into this European amendment.

• IEC 60529:
  International standard defining degrees of protection provided by enclosures (IP Code), a reference for ingress protection assessments.

• IEC 60034-5:
  Guidance on protection classes of rotating electrical machines, relevant for evaluating IP ratings beyond certification.

Summary

SIST EN 60079-7:2016/A11:2024 reinforces the safety of electrical equipment operating in explosive atmospheres by clarifying ingress protection requirements for terminal boxes in motors rated at or above 1 kV. By harmonizing with IEC interpretation sheets, this amendment ensures uniform compliance, enabling manufacturers and users across Europe to enhance safety without ambiguity. This standard is crucial for industries handling explosive environments, providing clear directives that facilitate safer electrical equipment design, testing, certification, and deployment.
