"To prepare international standards for systems and elements used for industrial process measurement, control and automation. To coordinate standardization activities which affect integration of components and functions into such systems including safety and security aspects. This work of standardization is to be carried out in the international fields for equipment and systems.

TC 65 has a Cybersecurity horizontal function in accordance with IEC Guide 108, defined as follows: Cybersecurity for Operational Technologies which includes:

• Whole lifecycle from design to disposal (including supply chain, etc.)
• Technical, organizational and procedural requirement
• Components, subsystems and systems."

To co-ordinate the standardization of those features of related elements which affect suitability for integration into such systems. The work of standardization outlined above is to be carried out in the international fields for equipment and systems operating with electrical, pneumatic, hydraulic, mechanical or other systems of measurement and/or control.
