Assess whether an in-house wound magnetic component and its delivered batch carry the build basis, the thermal margin and the screening the lowest assurance class of ECSS-Q-ST-60-13C clause 6.6.8 asks for: refuse a drawing with no issue, an unreleased winding procedure, an uncertified operator or a missing first article record, solve the copper-loss heat balance in closed form for the hot spot and report a winding whose solution does not...

Use when a datasheet band meets an application case before a Class 3 part is baselined. Evaluate whether the rated temperature limits of a commercial EEE part cover the application conditions at the lowest assurance class of ECSS-Q-ST-60-13C clause 6.2.2.6: resolve the rated band from the temperature grade or the declared limits, widen the predicted extremes by the thermal analysis uncertainty, credit a correlated thermal model only down to its retained floor, take the cold end and the hot en...

Use when a light traceability folder has to become a depth verdict. Determine how deeply a lowest assurance class commercial EEE delivery can still be followed into the assembly it was fitted to, under ECSS-Q-ST-60-13C clause 6.5.4: resolve each installation back through kitting and re-batching records to its goods-in entry, cap the depth a pooled batch may claim, take the achieved depth as the weakest link on that chain, name every chain that never reaches goods-in, catch a record dated afte...

Evaluate whether a component control plan for a commercial-parts programme carries the content its data item fixes under ECSS-Q-ST-60-13C Annex A.

Use when fuse procurement test results have to become a lot verdict. Evaluate a commercial fuse lot against its procurement test matrix under ECSS-Q-ST-60-13C Table 8-4: validate each row's method, sample size and accept number, size the destructive sample budget so units consumed by fusing and breaking-capacity runs are bought on top of the flight quantity, judge voltage-drop readings against their limit, check every fusing time against the window declared for the overload multiple, treat a ...

Assess whether a supplier internal specification controls a commercial part purchase as its data item requires under ECSS-Q-ST-60-13C Annex C. Use when a supplier offers its own document in place of a space procurement specification and the buyer must judge it: refuse a specification with no reference or issue, check it fixes the part identification, the site and process baseline, the screening and lot-acceptance operations, the ratings, the marking and traceability rules and the change-notif...

Audit whether a commercial part justification document can be issued. Use when an Annex F data item under ECSS-Q-ST-60-13C has to be judged complete: name every required section the draft never wrote, validate each entry's part, intended application, usage decision, rationale, residual risk and approving authority, hold each decision to its own evidence demand, refuse a high residual risk carried on an accept-as-is decision with nothing behind it, reconcile justified parts against the declare...

Determine whether a screened legacy lot passes the ECSS-Q-ST-60-13C Table 8-14 acceptance list. Use when an intermediate-assurance lot of legacy commercial active parts has completed lot acceptance and the campaign has to become an accept-or-hold verdict: size every group from the banded sampling plan keyed on the lot, judge each group accept-on-zero because acceptance consumes what it tests, confirm the devices sampled came from the lot being accepted, subtract the consumed devices from the ...

Evaluate a legacy active part type against the ECSS-Q-ST-60-13C Table 8-12 evaluation list. Use when a legacy commercial active part is being adopted at the intermediate assurance class and an executed evaluation campaign has to become an evaluated-or-repeat verdict: confirm every table grouping was performed at or above its required sample, hold a grouping that consumes its devices to accept-on-zero, require devices drawn from more than one production lot so the result describes the part typ...

Assess a legacy screening run against the ECSS-Q-ST-60-13C Table 8-13 test list. Use when an intermediate-assurance lot of legacy commercial active parts has been screened and the run has to become a screened-or-reject verdict: walk the sequence in order carrying survivors from each step into the next, refuse a declared population that does not follow from the previous step's rejects, hold a step that tested a sample instead of the whole population, take the burn-in percent defective on the d...

Verify a legacy lot against the ECSS-Q-ST-60-13C Table 8-15 acceptance list. Use when an active commercial part is being accepted at the lowest assurance class and a reduced campaign has to become an accept-or-hold verdict: run the core groups on the delivered lot itself, let a non-consuming group carry an accept number while a consuming one stays accept-on-zero, admit heritage evidence for the remaining groups only when it covers the same part type from the same site inside its validity wind...

Use when inductor or transformer procurement test data has to become a lot verdict. Evaluate a commercial magnetic part lot against its procurement test matrix under ECSS-Q-ST-60-13C Table 8-5: validate each row's method, sample size and accept number, correct every winding-resistance reading back to the reference temperature before it meets its limit, apply a maximum to resistance, a minimum to insulation resistance and a two-sided band to inductance and turns ratio instead of one comparison...

Use when a part has to be matched to its procurement test table. Determine which per-family procurement test matrix governs a commercial part under ECSS-Q-ST-60-13C clause 8.2: resolve the part family from the component type and the technology together rather than from either field alone, map that family to its procurement test table, split the table into the test groups applicable at the declared assurance class and the groups the class defers, report applicability as a fraction judged under...

Use when a part carries pure tin terminations. Assess the whisker risk of a pure tin termination and derive the controls it needs under ECSS-Q-ST-60-13C clause 9.2: decide from the lead content by mass whether a tin finish counts as pure tin at all, bound the whisker length reachable over the mission from the finish type, underplate, substrate, plating thickness and any conformal coat, divide the minimum conductor spacing by that bound for a bridging margin, double the margin required where t...

Evaluate whether a declared resistor chip test matrix meets its programme and turns a lot into an accept or hold verdict.

Determine which radiation effect mechanisms are credible for a component and what each demands. Use when the ECSS-Q-ST-60-15C clause 4.2 mechanism set has to be narrowed to one part: take the mechanisms its technology is open to, screen each against the environment so a cumulative effect needs its own driving quantity and a single event needs the environment to reach the part's onset, group the survivors into cumulative and single event families, separate the ones a single occurrence can dest...

Evaluate the non-ionising dose a part takes and the margin it leaves. Use when ECSS-Q-ST-60-15C clause 5.2 has to be applied to a displacement-damage case: accumulate the dose over direction by a statistical solid-angle sector ray trace or by a Monte Carlo ray sample, judge that sampled mean by its own ray count and standard error, divide the demonstrated displacement capability by the dose and hold it to the minimum design margin of this clause, and require a displacement damage test whereve...

Audit the mission radiation environment specification for the content Annex A requires. Use when ECSS-Q-ST-60-15C Annex A has to be applied to that deliverable: check the orbit definition, each trapped, solar particle and cosmic ray population, and the derived dose-depth, displacement fluence and linear energy transfer products are all present, that every modelled environment names its model, its version and the standard it was drawn from, that a statistical fluence declares its confidence le...

Define the consolidated radiation environment and hardness assurance requirement baseline a system review can settle. Use when the ECSS-Q-ST-60-15C clause 4.4.2 phase B work has to be produced or graded: check every requirement for an environment source, a design factor at or above the floor of its allocation level and a stated verification method, weight a dose-depth curve by the solid-angle fraction of each shielding sector to obtain the equipment location dose, screen the candidate part li...

Use when the ECSS-Q-ST-60-15C clause 4.4.3 phase C work has to be produced or graded: reduce each characterization lot to a design capability through a one-sided tolerance limit that penalises a small sample, add the spot shield to the inherent thickness and read the dose-depth curve at the total, price that shield in mass against its allocation, take every part's radiation design ma...

Evaluate the flight lot radiation verification campaign and the hardness assurance actions still open before a production milestone. Use when the ECSS-Q-ST-60-15C clause 4.4.4 phase D work has to be produced or graded: decide which delivered lots owe a verification test from the part category and whether heritage data on the same diffusion lot covers them, accept or reject each tested lot on its worst result over a sample as large as the category demands, and report every assurance action due...

Review the radiation analysis report deliverable for content and traceability. Use when ECSS-Q-ST-60-15C Annex B has to be applied to that report: confirm it carries the analysed configuration, the environment inputs, a section per radiation effect, the applied margins, the mitigation decisions, the test evidence and the parts-list cross-reference, then take each analysis entry and require a margin against its stated requirement, a named mitigation decision behind every shortfall, and a real ...

Evaluate whether measured parameter drift shows a part damaged by radiation. Use when the ECSS-Q-ST-60-15C clause 4.3 evaluation basis has to be applied to a drift run: reduce every reading to one excursion that rises toward failure whichever way the parameter moves, interpolate the exposure level at which it leaves its limit, report a run that never left as censored at the highest level applied rather than inventing a crossing, flag drift that recovered between steps, and take the worst samp...

Derive the part-level radiation requirement a mission environment implies and the margin each part holds. Use when the ECSS-Q-ST-60-15C clause 4.1 assurance flow has to be walked end to end: check the declared stages against the canonical order and name every absent one, carry the mission environment through a dose-depth curve by log-log interpolation to each part's own shielding, refuse a thickness the curve does not span rather than extrapolating, apply the design factor to obtain the speci...

Assess whether the radiation analysis reporting reaches each project milestone review at the depth and on the date that review is owed. Use when the ECSS-Q-ST-60-15C clause 4.5 reporting obligation has to be planned or graded: read the depth an equipment category owes at a given review from the closed depth ladder, count working days back from the review date to turn that depth into a submission deadline, and grade every report separately on delivery, on depth against what was demanded, and o...

Map radiation hardness assurance activities and deliverables onto the project lifecycle phases and say which ones sit in the wrong place. Use when the ECSS-Q-ST-60-15C clause 4.4 phase mapping has to be graded: normalise each declared phase against the canonical sequence, place every assurance activity inside its earliest-to-latest phase window, flag work scheduled before the inputs exist or after the review that consumes it, enforce the precedence pairs that make one activity depend on anoth...

Assess whether a part's single event susceptibility is survivable in its mission. Use when ECSS-Q-ST-60-15C clause 5.3 has to be applied to test data: separate recoverable upsets, transients and functional interrupts from the destructive latchup, burnout and gate rupture, read the integral flux at the part's linear-energy-transfer threshold, turn saturated cross-section and device count into an event rate against the system budget, and for a destructive event not excluded by threshold check t...

Use when ECSS-Q-ST-60-15C clause 5.1 has to be applied to a parts list: read the local dose off the mission dose-depth curve at each part's equivalent aluminium shielding, scale it to the radiation lifetime the design must cover, divide the demonstrated dose capability by that design dose for the achieved radiation design margin, take the required margin from the evidence grade the capability rests on and t...

Determine which hardware the ECSS-Q-ST-70-01C cleanliness and contamination-control requirements apply to, then group each in-scope item by how much contamination it can tolerate. Use when an inventory mixes flight hardware, ground equipment and facility items and every item needs an applicability decision plus a sensitivity band before any cleanliness level is chosen: screens the three routes into scope, refuses an unjustified exclusion, bands the item separately on its obscuration budget an...

Determine which cleaning process a piece of flight hardware can actually take, and which of the admissible ones reaches the level it needs. Use when solvent wipe, aqueous immersion, plasma and carbon-dioxide snow are all on the table and the item carries material, geometry and sensitivity constraints that rule some of them out. Screens each candidate for material attack, trapped-liquid geometry, optical and electrostatic sensitivity and residue the item cannot carry, keeps only the survivors,...

Verify that a cleaning operation actually reached the level it was run for, from the measurements taken afterwards. Use when particle counts per size band, a residue rinse sample and its witness blank come back from a cleaned surface and someone has to say accept, re-clean or re-sample. Converts counts over the sampled area into an obscuration figure and a ladder position, subtracts the blank and refuses a run whose blank exceeded the sample, treats a net mass under the balance floor as a bou...

Evaluate a measured cleanliness value against its acceptance criterion and route what an exceedance creates. Use when a particulate or molecular result has landed near or beyond its limit under ECSS-Q-ST-70-01C: spend the expanded measurement uncertainty on the side of the party making the claim so a straddling value repeats the measurement rather than the cleaning, size the exceedance as a multiple of the limit, group it as minor or major with criticality and recurrence, and route it to re-c...

Audit the contamination-control practices of a cleanroom facility or a supplier against ECSS-Q-ST-70-01C. Use when a facility has to be surveyed before flight hardware is allowed into it, when a supplier's cleanliness performance is being checked on site, or when the next re-audit has to be dated: score every practice area against its weight, categorize each finding as major, minor or observation, compute the weighted conformity index, decide whether the facility is approved, approved with co...

Allocate an end-of-life contamination allowance down the system, subsystem and unit levels of a programme under ECSS-Q-ST-70-01C. Use when one deposition figure on a critical surface has to become allocations each supplier can be held to, and the tree then has to close.

Produce and keep current the contamination and cleanliness control plan a project owes under ECSS-Q-ST-70-01C. Use when a CCCP has to be drafted, or an issued one has to be shown to still be the controlling document. Checks every content area points at a real section, that the plan speaks to each lifecycle phase from design through the launch campaign to operations, that a recognised authority approved it, that its issue postdates the last configuration change, that the periodic review is not...
