ECSS-Q-60B: Electrical, electronic and electromechanical (EEE) components (17 July 2007)

This Standard has been cancelled and replaced by ECSS-Q-ST-60C (31 July 2008).

1.1 General
This standard defines the requirements for selection, control, procurement and usage of EEE components for space projects.
This standard differentiates between three classes of components through three different sets of standardization requirements (subclauses) to be met.

  • Class 1 components are described in Clause 4.
  • Class 2 components are described in Clause 5.
  • Class 3 components are described in Clause 6.

1.2 Objectives
The objective of the EEE component selection, control, procurement and use requirements is to ensure that the EEE components used in a space project allows the project as a whole to meet its mission requirements. Important elements of EEE component requirements include:

The main tools which can be used to reach the objective are:

  • concurrent engineering,
  • standardization of EEE component types,
  • characterization of components,
  • assessment of component manufacturers including declared competencies and processes,
  • testing, screening, lot acceptance and periodic testing,
  • procurement specifications,
  • control and inspection,
  • control of nonconforming materials,
  • assessment and use of existing components data,
  • control of EEE Components with specific attention being given to those with limited data or confidence, and
  • information management.

1.3 Basic approach
The customer of a given space project defines the EEE component requirements within the boundaries of this standard. They appear in the appropriate clauses of the project requirements as defined in ECSS-M-00.
The supplier ensures that all relevant parts requirements are passed down to lower level suppliers and ensure that they are compliant to these parts requirements.
The supplier then defines a component control plan to implement those requirements into a system which enables, for instance, to control the selection, approval, procurement, handling in a schedule compatible with his requirements, and in a cost efficient way.

1.4 Applicability
The provisions of this document apply to all parties involved at all levels in the realization of space segment hardware and launchers.
