IEC TC 5

IEC TC 005 (Steam Turbines)
Specifications and Standards for the Rating and Testing of Steam Turbine

IEC Technical Committee 5 (IEC TC 5) develops International Standards for steam turbines used in power generation and industrial applications.
These standards cover the design, performance, testing, operation, maintenance, and safety requirements of steam turbine systems.

IEC TC 5 standards help ensure the efficiency, reliability, and long-term performance of steam turbines operating in thermal, nuclear, and combined-cycle power plants.
They are widely used by manufacturers, utility companies, engineering contractors, inspection organizations, and maintenance professionals worldwide. The committee’s publications support consistent engineering practices, equipment interoperability, and compliance with international quality and safety requirements.

IEC TC 5 standards are essential references for engineers involved in the specification, installation, commissioning, and lifecycle management of steam turbine equipment.
