This standard addresses the requirements for performing verification by testing of space segment elements and space segment equipment on ground prior to launch. The document is applicable for tests performed on qualification models, flight models (tested at acceptance level) and protoflight models.

The standard provides:

Requirements for test programme and test management,

Requirements for retesting,

Requirements for redundancy testing,

Requirements for environmental tests,

General requirements for functional and performance tests,

NOTE Specific requirements for functional and performance tests are not part of this standard since they are defined in the specific project documentation.

Requirements for qualification, acceptance, and protoflight testing including qualification, acceptance, and proto-fight models’ test margins and duration,

Requirements for test factors, test condition, test input tolerances, and measurement uncertainties,

General requirements for development tests pertinent to the start of the qualification test programme,

NOTE Development tests are specific and are addressed in various engineering discipline standards.

Content of the necessary documentation for testing activities (e.g. DRD).

 

Due to the specific aspects of the following types of test, this Standard does not address:

Space system testing (i.e. testing above space segment element), in particular the system validation test,

In-orbit testing,

Testing of space segment subsystems,

NOTE Tests of space segment subsystems are often limited to functional tests that, in some case, are run on dedicated models. If relevant, qualification tests for space segment subsystems are assumed to be covered in the relevant discipline standards.

Testing of hardware below space segment equipment levels (including assembly, parts, and components),

Testing of stand-alone software,

NOTE For verification of flight or ground software, ECSS-E-ST-40 and ECSS-Q-ST-80 apply.

Testing of two-phase heat transport equipment,

NOTE For acceptance and qualification testing of two-phase heat transport equipment, ECSS-E-ST-31-02 applies.

Tests of launcher segment, subsystem and equipment, and launch facilities,

Tests of facilities and ground support equipment,

Tests of ground segment.

 

This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00. Annex D gives guidelines for performing this tailoring.

This document is applicable to Resilient Element for Floating Slab system (REFS) – Elements used in floating slab and defines the test procedures and their acceptance criteria.

The document covers not only those parameters related to the effectiveness of a track structure in mitigating vibrations, that is, to reduce the emission of vibrations and structure-borne noise, but also the parameters that are needed for the static analysis and for the verification of track safety.

Floating slab track systems in the form of track base plates and track troughs are individual solutions in which there is considerable variation in the engineering design and the types of resilient elements used. For this reason, a floating slab track system is always an individual engineering solution and therefore, it is not possible to define all specific conditions for the resilient elements in the present document

The most typical types of resilient elements are:

—    Full surface bearings,

—    Strip bearings,

—    Discrete bearings (including the helical steel spring element),

—    Vertical bearings.

This document provides particular information in the following areas:

—    tests methods, tests arrangements and evaluation criteria of Resilient Element for Floating Slab system,

—    data supplied by the purchaser and by the supplier,

—    definition of general process of homologation,

—    definition of routine tests.

This document defines the specific test procedures for REFS:

—    stiffness tests,

—    fatigue tests,

—    severe environmental condition test.

This document also sets out procedures for testing fitness for purpose and provides information on quality monitoring as part of quality assurance procedures. This document does not, however, contain requirements pertaining to the functions of Resilient Element for Floating Slab system. It is the responsibility of the purchaser to define these requirements and to choose the optional tests.

This document is not applicable for fastening system and for booted concrete block and sleeper completed with boots covered by EN 13481‑5.
