This part of the IEC/TS 62239 series defines the requirements for developing an Electronic Components Management Plan (ECMP) to assure customers and regulatory agencies that all of the electronic components in the equipment of the plan owner are selected and applied in controlled processes compatible with the end application and that the technical requirements detailed in Clause 4 are accomplished. In general, the owners of a complete electronic components management plan are avionics equipment manufacturers. This part of the IEC/TS 62239 series provides the minimum requirements for system development assurance levels according to levels A, B and C of the DO-254 A, B and C for flight equipment.

Although developed for the avionics industry, this process may be applied by other industrial sectors.
