BS EN IEC 60079-0-2018 + A11-2024 PDF

Full title and description

STB BS EN IEC 60079-0:2018 + A11:2024 — Explosive atmospheres — Part 0: Equipment — General requirements. This entry is the 2018 EN adoption of IEC 60079-0 with Amendment A11 (2024) incorporated to reflect IEC interpretation sheets and clarifications affecting general requirements for electrical equipment intended for use in explosive atmospheres.

Abstract

This standard defines the fundamental principles, constructional and testing requirements, marking, and documentation for electrical equipment and protective systems intended for use in potentially explosive atmospheres (gas, vapour, mist and dust). Amendment A11:2024 provides updates and editorial/technical clarifications aligned with IEC 60079-0 interpretation sheets to ensure consistent application and to address recent technical issues identified by the international committee.

Scope

Specifies the general constructional and testing requirements and the associated documentation and marking for electrical equipment and protective systems intended for use in explosive atmospheres. A11:2024 supplies targeted updates to align the EN edition with IEC 60079-0:2017 interpretation sheets (ISH1:2019 and ISH2:2019), resolving points of interpretation and providing clarifications for application, testing and compliance assessment.

Key topics and requirements

• Definitions and fundamental principles for equipment intended for explosive atmospheres.
• Classification of equipment protection techniques and protection concepts (e.g., Ex d, Ex e, Ex i, Ex n, Ex p, Ex q, etc.).
• Design and construction requirements to avoid ignition sources (electrical and non-electrical).
• Temperature classification and surface temperature limits.
• Ingress protection and environmental considerations affecting explosion safety.
• Routine and type testing procedures (electrical, mechanical, thermal, and environmental tests).
• Marking, documentation, instructions for safe use, and conformity assessment requirements.
• Requirements for protective systems, interlocks and equipment modification control.
• Guidance on selection, installation and maintenance where relevant to safe operation in explosive atmospheres.

Typical use and users

Manufacturers and designers of electrical equipment for potentially explosive atmospheres; testing and certification bodies; notified bodies and conformity assessment organizations; end-users and plant operators in oil & gas, petrochemical, chemical, pharmaceutical, mining, grain handling, and other sectors where flammable gases, vapours or combustible dusts may be present; standards committees and regulatory authorities responsible for equipment safety and installation rules.
