1. Safety: The primary purpose of IEC 60949 is to ensure the safety of people and equipment in hazardous locations. By following the standard, manufacturers can design and produce electrical equipment that minimizes the risk of accidents and explosions.
2. Compliance: Many countries and industries require compliance with IEC 60949 for electrical equipment used in hazardous locations. Manufacturers who comply with the standard can demonstrate their commitment to safety and regulatory requirements.
3. Interoperability: IEC 60949 promotes interoperability by providing a common framework for electrical equipment used in hazardous locations. This enables manufacturers to design and produce equipment that can be used globally, reducing costs and increasing efficiency.

non-adiabatic factor

For longer durations or specific cable types (like those with metal sheaths), heat loss to the insulation or surrounding environment becomes significant. IEC 60949 provides a to adjust the adiabatic current, allowing for a higher permissible current because some heat is dissipated. 3.
