Define the implementation requirements for a space-project hazard analysis under ECSS-Q-ST-40-02C clause 5.2.1, step 1. Use when the task is fixing what the analysis must cover before a single hazard is written down: reading the project type - crewed or uncrewed, ground, launch, orbital or re-entry segment, hardware recovered, third party exposed - into the analysis depth it forces, deriving the scope elements, the technique set and the specialist disciplines the safety team has to hold, then...

Identify and assess the hazards of a space system under ECSS-Q-ST-40-02C clause 5.2.2, step 2. Use when the task is working all four identification sources - the generic hazard library, the system functions, the planned operations and the induced or natural environments - into one hazard list, then giving each entry a severity category and a likelihood band drawn from evidence rather than opinion, banding a quantified per-mission probability instead of carrying the number forward, and reading...

Evaluate the risk-reduction measures proposed for a space-system hazard under ECSS-Q-ST-40-02C clause 5.2.3, step 3. Use when the task is holding a control set to the hazard-reduction precedence - eliminate or minimize by design first, then a safety device, then a warning device, then a procedure or training - refusing a weaker order that carries no written justification for the orders it skipped, demanding verification evidence before any measure is credited, and recomputing the residual sev...

Verify the tracking, acceptance and communication of space-system hazards under ECSS-Q-ST-40-02C clause 5.2.4, step 4. Use when the task is driving each hazard report through its hazard-log status states in a legal order, rejecting a jump from open straight to accepted, matching the acceptance authority to the residual severity so a catastrophic residual is never signed at working level, grading the acceptance record for its rationale, evidence reference, named signatory and date, and listing...

Execute a fault tree analysis to the IEC 61025 procedure adopted by ECSS-Q-ST-40-12C: validate the tree for dangling references, cycles and malformed AND, OR and k-out-of-n gates, expand it to minimal cut sets, evaluate those cut sets qualitatively by order, quantify the top event exactly by inclusion-exclusion and against the rare-event and min-cut-upper-bound estimates, rank contributors by Birnbaum, Fussell-Vesely and criticality importance, sweep the sensitivity of any basic event, and as...

Evaluate a software tool offered to support fault tree analysis under ECSS-Q-ST-40-12C: match what the tool computes against what the analysis actually needs, grade its results against reference cases inside a declared tolerance, compare two runs of one model for repeatability, verify that the model survives an export and re-import in the required exchange formats, derive the qualification effort the result consequence demands, and close with an acceptance verdict plus the restrictions that r...

Scope fault tree analysis inside an ECSS project under the ECSS-Q-ST-40-12C adoption of IEC 61025: categorize the need as top-down consequence reasoning or bottom-up failure-mode enumeration, decide whether a tree, an FMECA or both carry the work, name the analyses the tree feeds — hazard analysis under ECSS-Q-ST-40-02 or the dependability analyses of ECSS-Q-ST-30C — set the depth as qualitative or quantitative, and compute how far the basic events trace back to declared failure modes. Use wh...

Determine the safety analysis suite an ECSS-Q-ST-40C clause 7.2 to 7.4 programme owes at a given lifecycle phase, reading the Annex A applicability matrix: resolve which analyses are mandatory and which only recommended, degrade an analysis to recommended where the worst severity carried sits below its floor, compare the resolution with the declared plan to expose missing analyses, analyses the phase has no use for and analyses due after the phase review, and report the coverage achieved. Use...

Determine which ECSS-Q-ST-40C safety requirement groups bite on a given product type at a given programme phase, using the informative applicability guidelines, and grade a tailoring proposal against that answer: a deletion of a group the guideline has biting needs a justification and customer agreement, a deletion before the group starts should have been a deferral, and retaining a group the guideline puts out of scope is cost rather than safety. Use when safety requirements are tailored ont...

Produce the declaration of conformity for a piece of ground equipment under ECSS-Q-ST-40C: screen the item against the EU instruments its own properties pull in — a powered moving assembly, a vessel above the pressure-volume product, a supply inside the low-voltage band, emitting electronics, an explosive-atmosphere zone, a lifting accessory — then settle the assessment route, say whether the conformity mark is carried at all, and list what is still missing before anyone signs. Use when groun...

Perform hazard reporting, review and close-out under ECSS-Q-ST-40C: hold every hazard control on its own row of the safety verification tracking log, discharge a control only when its row is closed, cites evidence and has that evidence accepted, add the safety review board behind a catastrophic or critical hazard and an acceptance reference behind any declared residual risk, then emit the hazard close-out statement and the log rollup. Use when hazards are taken to a safety review for closure....

Evaluate the operational safety provisions of an ECSS-Q-ST-40C clause 6.6 programme: rank every declared control against the design-elimination to procedure-and-training precedence, refuse a catastrophic ground hazard resting on procedure alone, require a verification behind each control, compare the reaction time a mission-control constraint needs with the time the operator has, and report the hazardous phases - transport, handling, integration, launch-site work - left with no operation. Use...

Allocate probabilistic safety targets across severity categories for an ECSS-Q-ST-40C clause 6.4.4 and Annex E safety case: refuse a target set that is not stricter as severity rises, split each severity's per-mission limit over the hazards contributing to it by declared weight, aggregate a group as a union of independent contributions rather than a naive sum, and place every predicted probability on the Annex E severity-probability acceptance matrix. Use when a quantitative safety target is ...

Produce the safety analysis report of ECSS-Q-ST-40C clause 7.5 to its Annex D data requirement: hold the section order, validate each hazard report for severity, causes, controls and a verification behind every control, trace each cause back to a FMEA/FMECA failure mode or a fault-tree basic event, expose the critical items no hazard report covers, and derive a status from the content so a hazard declared closed on an unverified control is caught. Use when the report is compiled, updated afte...

Identify and control the safety-critical functions of an ECSS-Q-ST-40C clause 6.5 design: decide criticality from the worst credible consequence, derive the failure tolerance that severity demands and the inhibits it needs, count only independent inhibits toward the tolerance achieved so a shared common-cause group collapses three inhibits into one, and assess the clause's control set - inadvertent-operation prevention, operator status information, safe shutdown, EEE component selection and s...

Verify a safety-critical function against ECSS-Q-ST-40C: read off the activities its criticality category owes — validation, qualification, failure testing, design and operational characteristic verification, safety verification testing — then discharge each one only on a passed record with an evidence reference, refuse a waiver at the top category, and grade failure testing by the fraction of declared failure modes it actually reaches rather than by whether a failure test happened. Use when ...

Plan safety verification under ECSS-Q-ST-40C: assign a method to each safety requirement — test, analysis, inspection, review of design, similarity — on the rule that rising severity withdraws the weaker methods, then check the assignment is supportable (analysis of a catastrophic requirement needs correlated test data behind it, similarity needs a named baseline item), that every requirement has a planned verification report, and that closure is planned no later than the review milestone its...

Use when an advisory lands on a part already on the declared components list. Evaluate an alert, errata sheet or manufacturer advisory against the class 1 EEE parts a programme has already selected, under ECSS-Q-ST-60C clause 4.5.3: match the advisory to declared-list entries, place each entry at its procurement stage, derive the action that stage earns from deselection through to an in-orbit impact statement, decide whether the part approval itself is invalidated and must be re-approved, fan...

Use when an ASIC is developed, reused or re-targeted. Determine which flow of the dedicated ASIC and FPGA development standard a class 1 application specific integrated circuit enters when ECSS-Q-ST-60C clause 4.6.2 hands it over: compare the candidate build against the qualified heritage on foundry, process node, mask set, design database, functional scope, package and die attach, group the moved axes into silicon, design and assembly, weigh the reuse evidence and the age of the qualificatio...

Use when a session held at the supplier has to become a ship-or-hold decision with a quantity attached. Determine whether a witnessed source buy-off releases a Class 1 EEE lot under ECSS-Q-ST-60C clause 4.3.6: count the whole days of advance notice the procuring entity was given, decide from who was actually in the room whether the session was witnessed, waived under a referenced waiver or simply unwitnessed, check that the activities it sits on top of completed no later than the session itse...

Use when a drafted plan has to become a maintenance verdict. Evaluate whether a component control plan is both prepared and still maintained as the highest reliability class demands under ECSS-Q-ST-60C clause 4.1.2.2: refuse a plan carrying no reference or issue, count the required chapters that stand on a procedure rather than a heading, measure the share of the revision interval the current issue has consumed, age every substitution request, supplier change, obsolescence notice, alert and n...

Use when a Class 1 equipment has to show its derating analysis reaches every part it contains. Evaluate whether every Class 1 part in an equipment design carries its stress reduction margin under ECSS-Q-ST-60C clause 4.2.2.5: reconcile the equipment parts list against the lines the derating analysis actually reached, build each worst-case applied stress from its nominal value, tolerance spread and transient uplift, turn each maker rating into the largest applied value the category margin leav...

Use when an audit report, a questionnaire or a third-party assessment decides whether a supplier may deliver Class 1 parts. Assess a part manufacturer against the European space component baseline for Class 1 use under ECSS-Q-ST-60C clause 4.2.3.2: weight each assessment criterion, derate its rating by the evidence source behind it, derate a stale audit down to the weakest source, grade the whole baseline so an unmentioned criterion counts as unassessed rather than excused, block approval on ...

Use when a lot must be traced into hardware or an assembly back to its lots. Maintain an unbroken identity trail for class 1 EEE parts from goods receipt through storage and kitting into finished assemblies, under ECSS-Q-ST-60C clause 4.5.4: link every issue and every assembly back to the receipt record that owns the lot, reconcile received quantity against issued, scrapped and remaining, reject an assembly that consumed a lot never issued to it, detect a storage bin that mixed two lots into ...

Use when a class 1 harness needs crimp contacts. Verify a removable contact may be fitted into a class 1 connector under ECSS-Q-ST-60C clause 4.6.6: fold the contact manufacturer name and test it against the approved source list, check the lot code, date code, conformance certificate and detail specification tie the delivery to that source, demand pair evidence when contact and shell come from different makers, test the wire gauge against the range the contact size accommodates and the applie...

Use when cross-section and internal-inspection results decide whether a part's construction is acceptable. Evaluate a constructional analysis carried out on Class 1 evaluation samples under ECSS-Q-ST-60C clause 4.2.3.3: size the sample set from the part family and the declared diffusion and assembly lots, check that the cross-sectioned samples actually span the lots and date codes they claim to speak for, grade every internal inspection step and treat a skipped mandatory one as incomplete rat...

Use when a declared components list delivery, equipment parts data package or list issue review is in front of you. Assess the declared components list a supplier issues for one Class 1 equipment item under clause 4.1.4 of ECSS-Q-ST-60C: select the items the clause obliges, grade each delivered file on whether it arrives in an editable exchange format a reviewer can revise rather than a flattened print carrying the same words, match the issued revision against the build standard the item is c...

Evaluate a delivered Class 1 EEE lot by destructive physical analysis under ECSS-Q-ST-60C clause 4.3.9. Use when partitioning a shipment into date-code groups, sizing the teardown sample each group owes, grading observed construction anomalies as major or minor from a project defect register, and testing wire bond pull forces against the minimum the wire diameter carries before turning the record into a lot disposition. Refuses an unregistered defect code, an unlisted wire diameter, a repeate...

Use when a model parts list, build-standard substitution or post-test part disposition is in front of you. Evaluate how parts fitted to an engineering qualification model are handled under the Class 1 rules of clause 4.1.6 of ECSS-Q-ST-60C: measure how far each fitted part's quality level sits below the flight-intended level, refuse a relaxation deeper than the programme allows and one left without a recorded substitution note, accumulate the thermal cycles, rework operations and powered hour...

Use when heritage, agency or commercial evidence is offered in place of a Class 1 qualification. Determine whether a candidate part needs a Class 1 evaluation and how much of one, when no qualification against an approved space specification stands behind it under ECSS-Q-ST-60C clause 4.2.3.1: weigh each prior-evidence claim by kind, test it for the same manufacturing line, the same part variant, no notified process change, validity and environment severity, take the strongest admissible clai...

Use when evaluation measurements have to become a candidate-part verdict. Evaluate whether the test programme run on a candidate class 1 EEE part meets the conditions and pass criteria of ECSS-Q-ST-60C clause 4.2.3.4: refuse a step whose applied severity misses the required value in the sense that step declares, keep an unexecuted mandatory step apart from a step that ran with no drift, turn every end-point reading into a drift fraction against its own drift limit and its absolute limit band,...

Use when a ground support equipment parts list, umbilical chain or test bench control scope is in front of you. Determine which electronic parts inside ground support equipment are directly connected to Class 1 flight hardware under clause 4.1.5 of ECSS-Q-ST-60C: walk each part's downstream chain to the flight connector, refuse a looping bench topology, break the chain only at an isolation stage that is itself qualified, keep a part behind an unqualified stage inside the boundary, then raise ...

Use when a class 1 lot is unpacked, moved between bays or reviewed before issue. Assess the handling, packaging and storage regime protecting a class 1 EEE lot under ECSS-Q-ST-60C clause 4.4: derive the packaging layers the part's fragility and moisture needs owe, test the container as received for seal integrity and a humidity indicator inside its threshold, return the transport shock peak as a fraction of the allowable, accumulate a thermal degradation index over the storage duration, name ...

Use when a class 1 part is applied above the high voltage threshold or in a high power microwave chain. Evaluate the additional provisions a class 1 EEE part owes when it runs at high voltage or high microwave power under ECSS-Q-ST-60C clause 4.6.7: stop a part whose working voltage sits above its own rating, test the voltage utilisation against the class 1 limit, flag an ambient inside the corona onset window and a sealed cavity with no vent path, derive the partial discharge, corona, ventin...

Use when a hybrid is about to be ordered. Evaluate a class 1 hybrid microcircuit purchase against the specifications ECSS-Q-ST-60C clause 4.6.3 lists for it: select the generic specification family from the hybrid's construction, confirm the order cites that family at an issue that has not been superseded with a detail specification behind it, test the supplier against the approval list and the week its approval lapses, and check every die, chip element and substrate inside the hybrid carries...

Use when a goods-in bench has to become a bonded-store or quarantine disposition. Assess whether a Class 1 EEE delivery may enter the bonded store on arrival at the procuring entity under ECSS-Q-ST-60C clause 4.3.7: name every document the evidence pack travelling with the parts is missing, take transit damage out of the accepted quantity instead of leaving it in, judge the shipping seal and the static-protective bag as findings about the pieces inside rather than about the wrapping, and reso...

Use when the inspection evidence for a class 1 parts programme is compiled or reviewed. Audit the inspection and control records a class 1 parts programme has produced under ECSS-Q-ST-60C clause 4.7: name every performed activity carrying no record at all, test each record for a traceable lot identity, a stated outcome, an authorised signatory, an evidence reference and a disposition behind every failed outcome, measure the retention shortfall against the programme retention period, and retur...

Use when a delivery has to become a submission plan rather than a pass-fail verdict. Plan which Class 1 EEE units of a delivery still owe a lot acceptance submission under ECSS-Q-ST-60C clause 4.3.5: split the delivery into one submission unit per part number, date code and manufacturer lot, size each draw with exact rational arithmetic that rounds the percentage rule up and clamps it between the declared floor and the unit quantity, and test every acceptance record on file for the same mater...

Use when a sample test result is about to be extended to parts nobody tested. Assess whether the class 1 parts drawn for lot testing genuinely stand for the whole delivered lot under ECSS-Q-ST-60C clause 4.5.5: stratify the lot on its declared production strata, size the required sample by exact integer ratio, allocate that sample across the strata by largest remainder, compare the units actually drawn against the allocation, and weigh the defectives found against the acceptance number. Refus...

Use when a class 1 delivery is booked in and its paperwork decides whether the parts reach stores. Verify the manufacturer data package delivered with a class 1 EEE shipment under ECSS-Q-ST-60C clause 4.3.11: derive the record set the lot's radiation duty, delta-qualification status, approved deviations and rework history owe, test every delivered certificate for an authorised signature, lot-code agreement with the box, an issue date at or before dispatch and coverage of the delivered quantit...

Use when an amplifier or converter stage needs a class 1 MMIC. Evaluate a microwave monolithic integrated circuit for class 1 use under ECSS-Q-ST-60C clause 4.6.5: take the foundry process, the source category and the delivery form, check the operating band sits inside the band the part was characterized over, resolve the channel temperature from baseplate, thermal resistance and dissipated power against the derating limit, compare applied against rated drive, group the electrostatic sensitiv...

Use when a class 1 part fails, is found out of specification, or repeats a failure mode across lots. Manage the nonconformance and failure control system a programme runs over its highest-assurance (class 1) EEE parts, under ECSS-Q-ST-60C clause 4.5.2: grade each report from its effect, its reach into built hardware and its safety consequence, derive the dispositions that grade allows and the signatures each disposition earns, decide when a failure analysis is owed rather than optional, impou...

Use when a Class 1 build has to show a chosen part's case and finish are allowed. Evaluate a candidate Class 1 part's packaging and material content against the ECSS-Q-ST-60C clause 4.2.2.2 restrictions: decide whether the case is hermetic, and for a non-hermetic one grade the agreed justification, the moisture sensitivity level and the demonstrated damp life against the humid hours the mission asks for; grade every surface finish against the near-pure-tin whisker threshold; grade each restri...

Use when a proposed parts list has to become a released flight parts list. Assess whether every EEE part proposed for class 1 flight use carries the customer review and sign-off of ECSS-Q-ST-60C clause 4.2.4: hold each submission to the mandatory evidence set, test the signatory both against the customer roster and for independence from the submitting organisation, treat an undated or out-of-validity sign-off as unreleased, release nothing on a conditional approval until every condition carri...

Use when a board minute has to become a part use verdict. Determine whether the parts control board has actually approved an electronic part for use at the highest reliability class under ECSS-Q-ST-60C clause 4.1.3: refuse a board missing a seat or a reference, test the quorum as attendance plus the chair rather than a headcount alone, weight the votes cast so an abstention withholds support, route each part category to the concurrences it depends on, require a decision reference and a record...

Use when a declared parts control organization has to become an adequacy verdict. Assess whether the unit accountable for electronic part control is constituted as the highest reliability class demands under ECSS-Q-ST-60C clause 4.1.2.1: refuse a unit with no name, lead or appointment behind it, take each required control function in turn, treat a function held by an unqualified name or funded below its effort floor as uncovered, compute the covered share and the effort-weighted staffing, nam...

Audit the witnessed pre-cap source inspection covering the Class 1 production lots of an order. Use when a lot is about to be sealed or its inspection record reviewed: place the witness point before the seal in the manufacturing flow, report an assembly or rework step running between the two, reject a witness who is not independent of the manufacturer, count the notice given in working days against the notice required, size the sample each lot owes, and admit an unwitnessed lot only against a...

Use when a Class 1 parts list has to show it was drawn preferentially from part one. Assess where each Class 1 part sits on the European preferred parts list, and what a step away from part one costs, under ECSS-Q-ST-60C clause 4.2.2.3: grade every candidate's listing tier, test whether a part one equivalent was searched for before a lower tier was taken and whether one was known to exist, dock the assurance for a missing procurement specification, then measure the part one share of the decla...

Use when a delivered lot has to be shown to match what was agreed. Verify that a purchase of class 1 EEE parts meets the technical baseline agreed for it under ECSS-Q-ST-60C clause 4.3.1: refuse a part number or manufacturer that is neither the baseline one nor a declared alternate, rank the ordered assurance level against the baseline rank, name every baseline requirement the order never flowed down to the supplier, and hold the delivered lot to the ordered quantity, the baseline temperature...

Verify that every Class 1 part type on an order is bought against one controlled purchasing specification in force. Use when a Class 1 procurement baseline has to be judged orderable: refuse a document with no identifier, issue or approving authority, reject a type carried by two specifications or by none, confirm the issue was effective on the order date, require the declared quality level, the named manufacturer and manufacturing line, an invoked procurement test programme and a lot traceab...
