ECSS-E-30 Part 7A – Mechanical – Part 7: Mechanical parts (25 April 2000)

This standard has been cancelled and replaced by ECSS-Q-ST-70C (6 March 2009).


Part 7 of ECSS-E-30 in the engineering branch of ECSS Standards defines mechanical engineering requirements for mechanical parts.

This Standard defines the requirements and statements applicable to the selection, design, verification and application of mechanical parts to promote the use of high-quality non-critical mechanical parts that achieve robust functionality and satisfy the mission performance requirements.

This Standard defines a pragmatic approach to the selection of parts by the mechanical and design engineer on the basis of their effect on the integrity of the equipment and to streamline the selection of space-proven rather than non spaceproven parts during the design of a new equipment in order to select the least number of different parts to satisfy the mission requirements.

It defines the content and extent of the mechanical parts and the requirements for its performance, design and test, product assurance and support activities.

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.

NOTE Tailoring is a process by which individual requirements of specifications, standards and related documents are evaluated, and made applicable to a specific project by selection, and in some exceptional cases, modification of existing or addition of new requirements.
