ECSS-Q-30B -Dependability (8 March 2002)

This Standard has been cancelled and replaced by ECSS-Q-ST-30C (6 March 2009).


This Standard defines the requirements for a dependability (reliability, availability and maintainability) assurance programme for space projects in order to comply with the ECSS policy as defined in ECSS-Q-00.

It defines the dependability requirements for space products. The requirements for the assurance of software products are defined in ECSS-Q-80. The dependability requirements for system functions implemented in software, and the interaction between hardware and software, are defined in this Standard.

The provisions of this document apply to all programme phases. When viewed from the perspective of a specific project context, the requirements defined in this Standard should be tailored to match the genuine requirements of a particular profile and circumstances of a project.


This Standard cancels and replaces ECSS-Q-30A Dependability (19 April 1996).
