ECSS-E-ST-10-03C, SPACE ENGINEERING: TESTING (01-JUN-2012)., The requirements on the systems engineering process are gathered in ECSS‐EST‐ 10; while specific aspects are further elaborated in dedicated standards, in particular: ECSS‐E‐ST‐10‐06, ECSS‐E‐ST‐10‐02 and the present standard (ECSSE‐ ST‐10‐03) In the System Engineering branch (ECSS‐E‐10) this standard aims at a consistent application of on ground testing requirements to allow proper qualification and acceptance of space products Experience has demonstrated that incomplete or improper on ground testing approach significantly increase project risks leading to late discovery of design or workmanship problem(s) or in‐orbit failure(s). Testing is part of the system engineering process as defined in ECSS‐E‐ST‐10. This starts at the early phase of the mission when defining verification process in terms of the model philosophy and test sequence and ends at the last testing phase prior launch. In the level of decomposition of a space system, this standard addresses the requirements for space segment element and space segment equipment. The document is organised such that: * clause 4 provides requirements for overall test programme, test management and test conditions, tolerances and accuracy; * clause 5 provides requirements for Space segment equipment; * clause 6 provides requirements for Space segment element; * clause 7 provides requirements for Pre‐launch testing. Clauses 5 and 6 are organised as follows: * general requirements for the products under test applicable to all models (clause 5.1 or 6.1); * requirements applicable to qualification model (clause 5.2 or 6.2); * requirements applicable to acceptance model (clause 5.3 or 6.3); * requirements applicable to protoflight model (clause 5.4 or 6.4); * detailed implementation requirements (clause 5.5 or 6.5); In the clause providing requirements for each model (i.e. clauses 5.2, 5.3, 5.4, 6.2, 6.3 and 6.4), the first table of the clause: * lists all types of test and defines their applicability and conditions; * links to the second table of the clause that defines tests level and duration; * provides reference to the clause defining the detailed implementation requirements for the given test (clause 5.5 or 6.5). For space segment equipment, the required sequence of test, for each model, is defined after the two tables in clause 5.2, 5.3 or 5.4. Since testing activities are part of the overall verification activities, test documentation to be produced (DRDís) are either specified in the ECSS‐E‐ST‐ 10‐02 (case of the test report) or in this document. Annex D gives guidelines for performing the tailoring of this standard as well as the generation of the compliance and verification matrices.
