Maintain the contamination history a flight item carries under ECSS-Q-ST-70-01C, held per serial number rather than per programme. Use when cleaning operations, exposure events and cleanliness measurements have to be kept as one ordered ledger, when the exposure a unit has accumulated since its last cleaning is in question, or when a review asks whether the record has gaps: validate every entry against its unit and date, order the ledger, refuse a duplicate or an unordered reading, accumulate...

Define what a particulate and a molecular cleanliness level mean and the units each is expressed in, following the ECSS-Q-ST-70-01C framework. Use when a programme has to write down its levels before any hardware is graded and the definitions must survive a change of inspected area or areal mass unit: builds the size-resolved count allowance from the level label and the declared distribution slope over a reference area, scales it onto the area actually inspected, turns the curve into an impli...

Manage the cleanliness margin a programme still holds against its allocated contamination budgets under ECSS-Q-ST-70-01C. Use when molecular and particulate allocations have to be tracked phase by phase from cleanroom build through test, storage, launch and orbit, or when a review asks how much of the end-of-life budget is already spent: check the apportionment against the top-level budget and the reserve held back, compute the margin and margin fraction each phase still carries, derive a con...

Evaluate whether a person is trained to work on flight hardware inside a contamination-controlled area under ECSS-Q-ST-70-01C. Use when access to a cleanroom zone is being granted, when training currency has to be checked before a hands-on operation, or when an escort ratio has to be set for untrained staff: derive the curriculum the role and the zone demand, compare it with the records held, compute how long each completed module still runs and which have lapsed, set the earliest refresher d...

Allocate a programme cleanliness requirement into the documents that actually bind a supplier and an integration team, then grade the result. Use when a top-level particulate, residue or largest-particle limit has to appear in purchase orders and in AIT procedures, and somebody must show that none of it was lost on the way down. Confirms each requirement reaches both document families, compares every carried limit with its parent, refuses a looser carried limit unless a waiver is cited, flags...

Define who holds each cleanliness activity on a project under ECSS-Q-ST-70-01C, covering the facility operators and the suppliers alongside the prime's own organisation. Use when a control plan needs its responsibility matrix built, or an existing one has to be shown to leave nothing unowned. Requires exactly one accountable party and at least one party carrying out each activity, a facility party in the loop wherever the facility decides the outcome, a supplier assigned to work done at a sup...

Assess the cleanliness status a programme has to put in front of a design or production readiness review under ECSS-Q-ST-70-01C. Use when the contamination data pack for a preliminary design, critical design, manufacturing readiness, test readiness or flight acceptance review is being assembled, or when a board has to decide whether contamination control is ready to let the next phase start: derive the items the review owes from its type and the contamination sensitivity of the hardware, comp...

Plan the verification of every cleanliness requirement on a space product. Use when a contamination control plan under ECSS-Q-ST-70-01C has to state, requirement by requirement, which measurement method substantiates it and at which programme point: match each particulate or molecular limit to a method whose detection floor sits below it by a declared margin, refuse a method whose minimum sample area exceeds the accessible surface, report a limit carried only by a qualitative look or a critic...

Document cleanliness verification results so every figure traces back to the hardware it came from and the level it was graded against. Use when a verification dossier is being closed out and each record has to name its hardware item, surface, sampled area, method, instrument and day before the achieved level can be believed. Grades the level ladder in the right direction, refuses a record whose instrument calibration had lapsed on the measurement day, marks a record superseded by later handl...

Determine the airborne particulate class an exposed-hardware operation needs and grade the clean area it has been given against that class. Use when an operation states a concentration it can tolerate at a threshold particle size and a facility offers a room, and the two must be reconciled before hardware is uncovered. Evaluates the ISO 14644-1 class ceiling from the size relation, runs it backwards to the least demanding class that still holds, refuses a threshold size outside the range the ...

Evaluate whether a clean-area work session is actually under control: gowning, materials, tooling, traffic and the headcount the ventilation can carry. Use when people, hardware and tools are about to enter a clean area and somebody must say whether the planned session holds the class or quietly breaks it. Computes occupant particle generation from the activity mix, converts it to a steady-state concentration against the air change rate and room volume, inverts that into the occupancy the roo...

Maintain the cleanliness a test article arrived with across an environmental campaign, phase by phase. Use when thermal-vacuum, vibration, acoustic, handling and storage phases each expose the hardware for known hours in a known environment and the contamination budget has to hold to the end. Accumulates particulate fallout from the cleanroom class and the exposure hours, adds molecular deposition driven by chamber loading and the shroud temperature difference, credits a covered, bagged or pu...

Determine the disposition a contamination nonconformance needs under ECSS-Q-ST-70-01C. Use when a measured molecular or particulate level has overrun the limit for a surface, when the performance the deposit costs has to be sized before a board sits, or when a re-clean is being proposed as the remedy: compute the exceedance against the limit, turn it into an optical or thermal performance penalty through the declared surface sensitivity, decide between use-as-is under concession, re-cleaning ...

Analyze the contamination sources a design carries — lubricants, adhesives, outgassing surfaces, particulate shedders — and size what each puts on the surfaces that matter under ECSS-Q-ST-70-01C. Use when a design holds a contamination allocation and the question is which items spend it and what would actually reduce them. Scales each emission rate to the source's own temperature, carries it through view factor, capture and exposure duration, credits only control measures with a verification ...

Identify the contamination sources a hardware item meets across its life cycle and rank the threats that actually reach its sensitive surfaces, per the ECSS-Q-ST-70-01C framework. Use when a contamination control plan is being written and the source register must be shown complete from manufacture through storage, transport and launch-site processing to orbit: converts each source into the arrival it delivers through its transport fraction, totals arrivals per species and per phase, names the...

Evaluate a design against the cleanliness provisions it owes under ECSS-Q-ST-70-01C: drainage, venting, material choice and surfaces a cleaning operation can reach. Use when a drawing set has been assigned a cleanliness level and somebody has to say whether the hardware can be built, cleaned and held there. Sizes each vent path from the depressurizing time constant it must achieve, finds trapped volumes with no drain, requires exposed-surface materials to come from the screened set, and grade...

Plan clean handling and integration for exposed flight hardware and grade the plan against a fallout allocation. Use when a sensitive surface is about to be uncovered on the integration floor and the gloves, covers, tooling, orientation and exposure time all have to be settled before the first contact. Converts the airborne concentration and the way the surface faces into an obscuration accumulation rate, computes the uncovered hours the allocation pays for, compares that with the planned ope...

Model the contamination a spacecraft inflicts on its own sensitive surfaces once in orbit. Use when material outgassing, thruster plume backflow, venting and released particles all reach an optic or a radiator and the mission deposition allocation has to be shown to hold. Integrates each decaying outgassing source analytically over the mission window, carries it to the surface through a view factor and a temperature-dependent sticking coefficient, adds the backflow share of the firings that c...

Plan the cleanliness controls that carry a spacecraft through a launch campaign without spending the budget it arrived with. Use when arrival, unpacking, integration, propellant loading, encapsulation, transfer and pad stay each have a duration, an environment and a protection state, and the fairing has to be verified before it closes. Accumulates particulate and molecular pickup stage by stage, credits a container, cover or purge only for what it blocks, refuses a loading stage run without v...

Calculate the total offgassing hazard index a hardware item adds to a crewed compartment and whether the atmosphere still closes. Use when equipment is installed in a habitable volume and the cleanliness case has to run from per-species offgassing rates, measured or scaled from installed mass, through the steady-state cabin concentration set by the air revitalisation path, to each species' share of its maximum allowable concentration, the summed total, the driving species and the separate air...

Evaluate a material against the vacuum outgassing screening of ECSS-Q-ST-70-01C when it sits in view of a contamination sensitive surface, reading the figures the ECSS-Q-ST-70-02C micro-balance method produces: take the recovered mass loss over the total wherever a water vapour regain was measured, tighten the condensable limit for the grade of surface in view, estimate the deposit from exposed mass, view factor and the source to collector temperature difference, compare it with the surface d...

Audit the instruments a cleanliness verification campaign will lean on before it starts. Use when balances, particle counters and spectrometers have to be cleared under ECSS-Q-ST-70-01C: walk each certificate forward by whole calendar months so a month end lands where the calendar puts it, report the days left on the measurement date, compare each detection floor against the tightest value it polices through a sensitivity ratio, combine independent contributions in quadrature against the tole...

Assess whether the particle population implied by a product cleanliness level threatens a mechanism, a bearing or a slip ring. Use when a moving assembly carries a cleanliness requirement and the argument has to run from the declared level to the largest particle expected over the real wetted area, then to the running-clearance margin, the contact-gap bridging outcome, the drag torque contamination adds to the actuator budget and the distance lubricant creeps toward a sensitive surface. Trigg...

Determine the molecular non-volatile-residue cleanliness level each hardware category must be built and delivered to under ECSS-Q-ST-70-01C. Use when a hardware list carries performance budgets rather than levels, and the residue density a surface may hold has to come out of its own sensitivity. Inverts the degradation budget through that sensitivity, subtracts what the item accumulates after delivery, then takes the least demanding ladder level still inside the remaining allowance, so nothin...

Derive a non-volatile residue surface density from a molecular cleanliness measurement. Use when a solvent rinse reduced gravimetrically or by infrared absorbance, or a witness plate standing in for an unrinsable surface, has come back under ECSS-Q-ST-70-01C: subtract the solvent blank, divide by the aliquot fraction taken for evaporation, turn an absorbance into a mass through path length and absorptivity, scale up for the residue the rinse left behind, transfer a plate reading onto the hard...

Compute the end-of-life molecular deposition budget of a sensitive optical surface and decide whether it holds. Use when an aperture, mirror, lens or detector window carries a molecular cleanliness requirement and the contamination-control plan has to apportion that budget across outgassing, plume backflow and handling sources, predict what each one deposits through its view factor and a temperature-dependent sticking coefficient, convert the accumulated areal mass into a condensed film thick...

Allocate the particulate cleanliness level a hardware item is held to, given its contamination sensitivity band and the obscuration its function can still absorb, per the ECSS-Q-ST-70-01C framework. Use when items have already been banded and each now needs a level written into its requirement, with the fallout of the environment it sits in taken into account: projects the accumulation over the remaining exposure, prices the obscuration each candidate level implies at delivery, applies the ma...

Assess the particulate-shedding materials of an installation against the cleanliness budget of ECSS-Q-ST-70-01C and decide the controls each one owes: resolve the shedding family of every paint, textile, blanket edge, foam, tape edge and hook-and-loop strip, take the control that family carries by construction, weight each source by its exposed area, the orientation of the receiving surface and the view factor between them, roll the exposure hours into a percent area coverage, compare the sta...

Convert a particulate cleanliness measurement into a number the requirement can be graded against. Use when a tape lift, a vacuum sample, an exposed fallout plate or an optical count has come back under ECSS-Q-ST-70-01C and the raw bins still have to become an obscuration: subtract the sampling-medium blank bin by bin and refuse a blank larger than the sample, scale the counts up for the fraction a lifting method leaves behind, normalise to the sampled area, sum the projected circle areas int...

Derive the governing cleanliness requirement at each propulsion fluid interface and say which specification imposed it. Use when a system cleanliness plan meets the propulsion subsystem and the two particle-size and non-volatile-residue limits have to be reconciled interface by interface, the filter sized from the smallest flow passage behind it, the passage-area blockage of a governing-limit particle quantified, and the tightest interface rolled up into the single pair the flushing and accep...

Assess hardware cleanliness at goods receipt and after transport, then name a disposition. Use when a package arrives, the bag and its indicator tell one story, the transport record tells another, and the measured residue and obscuration have to be judged against what the item was bought to. Compares each measurement with its limit, refuses a figure with no method named, reads packaging integrity and purge pressure, checks shock, humidity and elapsed shelf life, notices a receipt opened in an...

Determine the end-of-life power a contaminated solar array still delivers and whether its second-surface mirrors hold their ratio. Use when photovoltaic wings, cover glasses or optical solar reflectors carry a cleanliness requirement and the power budget has to carry particulate obscuration, molecular film attenuation, the cover absorptance rise that same film produces, the hotter cell it drives and the temperature derating that follows, instead of a flat contamination percentage. Trigger: ec...

Derive the packaging and storage provisions that hold a cleanliness level while hardware waits, and the interval at which the package must be opened and re-verified. Use when flight hardware leaves an integration hall for a store and somebody must state how it is bagged, purged and shelved, and when it has to be checked again. Validates barrier layers against the sensitivity, refuses packaging materials not permitted in contact with flight hardware, demands desiccant and purge state where the...

Evaluate how a molecular film and particulate fallout degrade a thermal-control surface and whether the radiator still closes. Use when a radiator, multi-layer-insulation outer layer or thermal coating carries a cleanliness requirement and the thermal budget has to carry the end-of-life solar absorptance rise, the emittance drop, the shifted alpha-over-epsilon ratio, the degraded radiative equilibrium against the sink and the extra radiator area that degradation costs, rather than one beginni...

Determine what a visual or black-light cleanliness observation can actually substantiate. Use when a surface is being verified by eye under ECSS-Q-ST-70-01C and the question is whether the conditions support the size the requirement needs seen: compute the resolvable particle diameter from viewing distance and assumed acuity, grow it for illuminance below the reference level and for foreshortening away from normal, confirm the lamp sits in the long-wave ultraviolet band with enough irradiance...

Evaluate outgassing screening results against the mass-loss and condensable limits their application carries under ECSS-Q-ST-70-02C. Use when a materials list has total mass loss and CVCM figures and each item has to be graded for the place it will serve, from a warm sealed box to the proximity of a cold optic. Picks the grading basis, crediting regained water back only where the application allows it, treats a sub-floor condensable reading as a bound, not a value, and carries a failing mater...

Determine whether a candidate space material owes the thermal-vacuum outgassing screening of ECSS-Q-ST-70-02C and grade the result it returns: read applicability from material category, environment, exposed mass and the contamination-sensitive surfaces in view, reuse valid data for the same material in the same processed condition, then compare total mass loss and collected volatile condensable material against their limits and recover the total once regained water vapour is removed. Use when...

Compute the collected volatile condensable material of a thermal-vacuum outgassing screening run under ECSS-Q-ST-70-02C. Use when replicate specimens have been baked and each collector plate carries a pre-bake and a post-bake weighing, and the run needs a defensible CVCM per specimen plus its replicate mean. Normalises every plate gain by the mass the specimen started with, holds a gain under the balance quantification floor to a bounded sub-floor statement instead of a small positive number,...

Maintain a materials data set from thermal-vacuum outgassing screening results under ECSS-Q-ST-70-02C, feeding the declared-materials practice of ECSS-Q-ST-70C and ECSS-Q-ST-70-71C. Use when finished screening reports have to become reusable entries and a submission meets records already held. Builds the entry key from designation, manufacturer, product form and processing state rather than the trade name, records values at the data-set resolution, refuses an entry whose source report was nev...

Audit the instrument set an outgassing screening run depends on. Use when the microbalance, the thermocouples and the pressure gauge have to be cleared under ECSS-Q-ST-70-02C before a run starts: walk each calibration forward by whole calendar months so a month end lands where the calendar puts it, report the days left on the run day, compare the tolerance each instrument polices against the uncertainty it carries, refuse a balance division too coarse for the mass change being sought, and com...

Determine which permitted variants of the thermal-vacuum outgassing screening test of ECSS-Q-ST-70-02C a material calls for, and the cost each carries. Use when a run departs from the baseline: a water-vapour regained determination, a longer preconditioning period for a hygroscopic material, a bake below the screening temperature for a low maximum-use-temperature material, or a longer bake for a thick specimen. Matches every declared variant against the material property indicating it and aga...

Prepare the test items for a thermal-vacuum outgassing screening under ECSS-Q-ST-70-02C: size one specimen inside the working mass window, work out how many cut pieces of the stock reach it from geometry and density, check a piece fits the sample holder in some orientation, count the replicates and the carrier blanks a liquid or paste needs, net the carrier out of the balance reading, and grade the conditioning duration, temperature and humidity actually achieved. Use when cutting specimens, ...

Assess the test item offered to an outgassing screening run. Use when coupons are on the balance bench under ECSS-Q-ST-70-02C and the question is whether they still stand for the flight material: hold each piece inside the per-specimen mass window, require the replicate count the screening needs, compare exposed area per unit mass with the flight part instead of accepting a thinner slice, name every process attribute that drifted from the flight build, and refuse a preconditioning soak whose ...

Evaluate a thermal-vacuum outgassing chamber as it is built. Use when an apparatus set-up is signed off under ECSS-Q-ST-70-02C before specimens are loaded: pair every heated compartment with its own collector plate, turn the aperture diameter and the compartment-to-collector gap into the single flux fraction the method band is written against, report the temperature spread of each heated zone separately, hold each collector plate inside its controlled band, and require a base pressure comfort...

Validate the condition set written on an outgassing run sheet. Use when a screening run is being booked under ECSS-Q-ST-70-02C and the declared point has to be reconciled with the method: grade specimen temperature, collector temperature and soak duration against their own bands, treat chamber pressure as a ceiling that low vacuum satisfies, require a named rationale and approval reference for each parameter that departs rather than one blanket note, and add pump-down, stabilisation, soak and...

Analyze the run log of a thermal-vacuum outgassing exposure. Use when a soak has finished under ECSS-Q-ST-70-02C and the question is how much of it counts: check that pump-down, heating, stabilisation, soak and cool-down were stamped in the only order they can occur in, credit an interval only when the samples at both ends had specimen temperature, collector temperature and chamber pressure inside their limits together, gather the failing stretches into excursions with their causes, and repor...

Document the conditions, results and uncertainties of a thermal-vacuum outgassing screening run in the reporting format of ECSS-Q-ST-70-02C, or grade a report already issued. Use when a run is finished and the record must state the material tested, the conditions achieved, the values obtained and their uncertainty. Checks identification to batch and processing state, grades every recorded condition against its window, pairs an out-of-window condition with a recorded deviation, combines the un...

Determine the total mass loss of specimens taken through an outgassing screening. Use when the three weighings of a run under ECSS-Q-ST-70-02C have to become a screening result: refer the loss to the initial mass so light and heavy coupons are comparable, refuse a specimen heavier after the exposure as a weighing error, subtract the water taken back on to leave the recovered mass loss, report a loss smaller than the balance division as unresolvable rather than small, and grade the replicate s...

Convert ECSS-Q-ST-70-02C outgassing screening data into contributions to a molecular deposition budget under the contamination control practice of ECSS-Q-ST-70-01C. Use when a sensitive surface holds an areal allocation and each exposed material has a condensable screening figure and an exposed mass. Refuses a record that presents a screening percentage as an outgassing rate, forms a bounding source term, applies a pre-flight bakeout credit only against a bakeout on record, transports each so...

Build the acceptance test programme a processed anodizing batch owes, per batch and per part category. Use when a lot has come off the line and someone has to say what it is tested for and whether it is accepted: take the required test set from the part category, size the sample from the lot with a square-root plan and a category floor, work out how many witness coupons each rack owes for the tests that destroy what they touch, then judge the sample against the category allowance and separate...
