ECSS-Q-60A – Electrical, Electronic and Electromechanical (EEE) Components (19 April 1996)

This standard has been cancelled and replaced by ECSS-Q-60B (17 July 2007).

1.1 Scope

This standard defines the requirements for selection, control and procurement of EEE components for European space projects.

1.2 Objectives

The objective of the EEE component selection, control and procurement requirements is to ensure that the EEE components used in space projects will allow the project as a whole to meet its requirements in terms of functionality, quality, reliability, schedule, and cost.

Important elements are:

  • Components programme management
  • Components engineering
  • Components Quality Assurance

The main tools to be used to reach the objectives are:

  • standardization of types
  • definition of quality and testing levels
  • qualification of components and manufacturers
  • testing / screening / lot acceptance and periodic tests
  • procurement specifications
  • control and inspection
  • control of non–standard components
  • documentation and data definition

1.3 Basic Approach

For space projects the EEE component requirements will be defined in line with this standard by the customer and will appear in the appropriate clauses of the Project Requirements Document (PRD).

The supplier will make a EEE components apportionment of requirements to lower levels.

The supplier will define EEE component requirements within the boundaries of this standard based on the requirements of the system and its elements, and takes into consideration the operational and environmental requirements of the programme.

The supplier will then define a component control plan to implement those requirements into a system which enables to control the selection, approval, procurements, handling, etc. in a schedule compatible with his requirements, and in a cost–efficient way.

1.4 Applicability

The provisions of this document apply to all actors involved in all levels in the realisation of space segment hardware and its interfaces.
