International Electrotechnical Commission Updated Safety Standard
The IEC has released the third edition of the IEC 60598-2-24 standard for luminaires with limited surface temperatures.
Updated on Oct. 2, 2026 in Appliances
The International Electrotechnical Commission has published the 2026 edition of its global standard for luminaires with limited surface temperatures. This update replaces the previous 2013 version and introduces new thermal protection requirements for controlgear.
Why it matters
The standard is designed to mitigate safety risks associated with combustible dust or the ignition of materials that settle on light fixtures. By establishing these technical requirements, the commission aims to enhance safety protocols for electrical lighting equipment.
The IEC 60598-2-24:2026 standard covers electric light sources with supply voltages not exceeding 1000 V. The document explicitly excludes luminaires intended for use in explosive gas or dust atmospheres.
The players
International Electrotechnical Commission
This is a global non-profit organization that develops and publishes international standards for all electrical, electronic, and related technologies.
The details
The latest edition aligns clause numbering and structure with the broader IEC 60598-1 standard and incorporates updated references to the 2024 version. These changes specifically address the thermal regulation of built-in controlgear within the lighting units.
Timeline
The previous edition of the standard was released in 2013.
The third edition of the IEC 60598-2-24 standard was published on October 2, 2026.
Culture Shift
The updated standard represents a move toward harmonized global safety requirements for residential and commercial lighting systems. This follows the framework and technical alignment set by the IEC 60598-1:2024 standard.
Consumers and businesses may see updated safety certifications on new lighting products as manufacturers adopt these latest standards. These changes ensure that installed fixtures meet contemporary thermal protection benchmarks.
The takeaway
This update underscores the necessity for modern lighting hardware to include advanced thermal management to prevent fire hazards. Readers installing or upgrading light fixtures should ensure that new hardware complies with the latest safety documentation.
