ECSS-E-30 Part 3A Mechanical – Part 3 Mechanisms (25 April 2000)


This Standard has been cancelled and replaced by ECSS-E-ST-33-01C (6 March 2009).

Part 3 of ECSS-E-30 in the engineering branch of the ECSS Standards defines mechanical engineering requirements for mechanisms.

This Standard defines the requirements and statements applicable to the concept definition, design, analysis, development, production, test verification and in-orbit operation of space mechanisms on spacecraft, payloads and launcher elements in order to meet the mission performance requirements.

This Standard contains the list of mandatory requirements to achieve reliable operation of space mechanisms in orbit. It should also prevent anomalies during the development phase influencing schedule and cost efficiency of space programmes.

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.
