Scope

ISO 24065:2023 applies to high‑power solid‑state power controllers used in the primary electrical power distribution of aircraft. It covers the general performance requirements and specifies test methods for evaluating controller behaviour under normal operation, overload and fault conditions, and environmental stresses typical of the aerospace environment. The standard is intended to support designers, manufacturers and certification bodies by providing common criteria for performance verification.

Key topics and requirements

• General performance requirements for high‑power solid‑state power controllers (HPSSPC).
• Electrical characteristics and operational behaviour under normal load and overload conditions.
• Fault detection, interruption behavior and fail‑safe functional requirements.
• Thermal performance and temperature‑related test procedures.
• Environmental conditioning and tests relevant to aircraft (vibration, shock, temperature extremes, humidity).
• Test methods and acceptance criteria to verify compliance.
• Requirements to support reliability assessment and qualification for aerospace use.

Typical use and users

Used by aircraft OEMs, avionics and electrical‑power system designers, component manufacturers of solid‑state power controllers, test laboratories and certification authorities to define, design, test and verify HPSSPC devices intended for primary aircraft power distribution. The standard helps ensure consistent performance and supports procurement and qualification activities.

Related standards

Standards typically referenced in conjunction with ISO 24065 include aerospace environmental and electromagnetic compatibility requirements and relevant industry guidance for power distribution and electrical components. Users often consider environmental test standards and industry specifications used in aircraft certification programs when applying ISO 24065.
