Abstract

This activity will be the parallel development of EN 16603-20-30 (equivalent to ECSS-E-ST-20-30C) and its supporting handbook TR 16703-20-30 “Guidelines for the design, requirements and control of harness” (equivalent to ECSS-E-HB-20-30A). Scope: The ECSS standard shall cover (ECSS-E-ST-33-01C used as a content template): • Applicable/Reference standards, specifications and handbooks • Definition of harness and related terms (e.g. HMU, bundle, cable, wire, shield) in the frame of this spec. • Requirements - General requirements  Mission specific requirements  Marking & labelling  Parts and components  Redundancy  Technical Budget - Electrical design requirements  EMC (e.g. EMC classification, magnetic cleanliness, shielding, bonding, grounding, inductance)  Derating & Voltage Drop  Double Insulation  Splicing - Mechanical design requirements  Routing (e.g. segregation, bundling, bending, layering, redundancy)  Mechanical Stability (e.g. fixation, stiffness)  Integration (e.g. accessibility, tooling, layering, [de-]integratability) - Environmental requirements - Material selection constraints/ requirements - Verification & Control requirements  Electrical testing & verification  Mechanical testing (if required)  Environmental testing (if required) - Cleanliness requirements - Handling requirements - Manufacturing requirements - Deliverables / Documentation requirements  Definition of required engineering documentation to be provided with the harness hardware with reference to DRDs (incl. Harness Design and Technical Description) • DRDs The handbook shall provide best practice techniques, examples and process details w ith associated acceptance criteria (limits, dos and don'ts) - ideally w ith a reference to the respective requirement. The handbook shall be understood as a guideline/proposal to fulfil the requirements defined in the respective ECSS specification in acc. w ith the CNES standard: • Selection of components, tools and accessories • Harness fixation • Harness protection (e.g. use of heat shrinking sleeves, tapes, hoses) • Shielding and its application on connector/backshell level • Harness design, routing and distribution of w ires • Splicing • Labelling and marking
