ECSS-Q-ST-20C – Quality assurance (15 November 2008)

This Standard has been superseded by ECSS-Q-ST-20C Rev.1 (1 March 2013)


This Standard defines the quality assurance (QA) requirements for the establishment and implementation of a Quality Assurance programme for products of space projects.
Discipline related qualification aspects are complemented in standards specific to those disciplines (e.g. ECSS-E-ST-32-01 for fracture control).
For software quality assurance, the software product assurance standard, ECSS-Q-ST-80 is applicable.

This Standard is applicable to all space projects.

This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
