Overview
EN 60079-5:2015/A1:2024 is the CENELEC amendment to the European standard on Explosive atmospheres – Part 5: Equipment protection by powder filling "q" (based on IEC 60079-5:2015/AMD1:2022). This amendment updates terminology and marking requirements for electrical equipment, Ex components and parts protected by powder (sand) filling - commonly referred to as protection method "q" or "qb". The document was approved in December 2024 and is to be implemented nationally by the end of 2025.
Key topics and requirements
- Protection concept: Equipment protection by powder filling ("q") - a method where components are embedded in a particulate filling to limit ignition sources and heat transfer in explosive atmospheres.
- Test terminology updates: Amendment A1 renames specific test clauses:
- Clause 5.1.3 and 5.2.2 titles changed from Dielectric strength test of the filling material to Insulation resistance test of the filling material.
- Figure 2 title updated to reflect the insulation resistance test arrangement.
- Marking requirements: Equipment, parts and Ex components using powder filling must be marked "q" or "qb" in accordance with IEC 60079‑0, with additional marking as appropriate under the amendment.
- Normative references and compliance: The amendment endorses IEC 60079‑5 content; users must consult the normative references cited for correct application. National implementation dates and withdrawal timelines are specified.
Applications
- Use of EN 60079-5:2015/A1:2024 applies where electrical apparatus is intended for use in hazardous areas with explosive atmospheres, including industries such as:
- Oil & gas and petrochemical plants
- Chemical and pharmaceutical manufacturing
- Mining and mineral processing
- Grain handling and bulk material processing
- Typical applications include design and qualification of motors, junction boxes, luminaires, sensors and other components that may be powder‑filled to achieve explosion protection.
Who should use this standard
- Design and test engineers developing equipment for hazardous locations
- Manufacturers of Ex components using powder filling "q"
- Conformity assessment bodies and test laboratories performing insulation resistance and marking verification
- Compliance officers, procurement and safety managers ensuring equipment selection meets EN/IEC requirements
Related standards
- EN/IEC 60079‑0 (General requirements for explosive atmospheres) - referenced for marking and basic requirements
- The broader IEC 60079 series covering different protection concepts for hazardous area equipment
This amendment clarifies test nomenclature and marking practice for powder‑filled protection, helping manufacturers and certifiers maintain consistent compliance for hazardous‑area electrical equipment.
