Overview
SIST EN IEC 60695-2-10:2026 addresses fire safety in electrotechnical industries by specifying standardized test methods for evaluating thermal and fire hazards using a glow-wire apparatus. Developed by the International Electrotechnical Commission (IEC) and published by SIST, this standard forms part of the IEC 60695 series and serves as a core reference for assessing fire risks related to electrical equipment and insulating materials. The document defines apparatus requirements and outlines a common test procedure intended to simulate ignition hazards posed by overheated components, like glowing wires or overloaded resistors. This approach helps manufacturers quantify and mitigate the risk of fire under realistic, small-scale conditions.
Key Topics
- Apparatus Requirements: The standard prescribes material composition, geometry, and performance criteria for glow-wire apparatus, including integration of temperature measurement systems (thermocouple or pyrometer), and ensures reliable ignition simulation.
- Standardized Test Procedure: It provides a unified method for small-scale fire hazard tests, involving the application of a heated wire to materials or end products under controlled conditions.
- Thermal Stress Simulation: Tests simulate short-term thermal stress as would occur from faults like component overheating, mirroring real-world fire triggers.
- Assessment Criteria: Procedures for observing ignition, flame persistence, and fire propagation are detailed, supporting consistent fire hazard evaluation.
- Recent Updates: The 2026 edition introduces technical changes such as expanded use of pyrometers for temperature measurement (Annex D) and aligns terminology with ISO 13943:2017 for harmonized fire safety language.
Applications
SIST EN IEC 60695-2-10:2026 is essential for industries involved in the design, manufacture, and compliance testing of:
- Electrical and Electronic Equipment: Used to assess fire behavior in devices from household appliances to industrial machinery, ensuring product safety and regulatory compliance.
- Solid Electrical Insulating Materials: Helps manufacturers test plastics, composites, and other insulating materials for resistance to ignition and flame spread.
- Component and Product Certification: Forms a basis for certification and CE marking within the European market.
- Material Selection and R&D: Aids engineers and designers in comparing the fire hazard characteristics of different materials, supporting safer, more resilient product development.
- Regulatory and Market Access: Satisfies legal fire safety requirements in sectors where thermal hazards are a concern, supporting market entry in Europe and beyond.
Related Standards
For comprehensive fire hazard testing based on glowing/hot-wire methods, SIST EN IEC 60695-2-10:2026 should be used in conjunction with the following:
