Verify a repaired or modified area on a printed board assembly against the verification requirements of ECSS-Q-ST-70-28. Use when a repair is finished and the inspection evidence must be judged complete as well as passing. Derives the inspection set the work actually owes rather than grading whatever happened to be performed, then compares magnification with what the smallest feature demands, insulation and path resistance with their limits, a dimension with its band and radiographic voiding ...

Validate the authorization behind a proposed board repair or modification before any iron reaches the hardware. Use when a repair request is being signed off, an approval chain is being assembled, or a repair file is audited after the fact: it derives the minimum approving authority from the work type, the hardware model, the criticality of the function and whether the method is a listed one, compares that against the signature actually obtained, lists the file entries still owed, and grades ...

Determine whether a printed circuit board assembly stays inside the repair ceilings of ECSS-Q-ST-70-28C once a further repair is added. Read the count and density allowance the assurance level carries, combine the repairs already on the board with the ones proposed, refuse a reused site identity, measure the in-plane separation of every pair against the minimum that pair takes — longer on one face, shorter across the laminate — count repairs per conductor, and return the disposition with the ...

Assess whether an operator is qualified for the class of board repair in front of them. Use when a repair certification is issued, renewed or audited: it reads the training hours and the practical sample set that class demands, grades the samples actually made against the accept count and reports first-pass yield, applies the near-vision check validity at the assessment date, tests currency since the operator last worked that class, dates the certificate expiry, and names the action still owe...

Plan an authorized printed-circuit-board repair before the operator starts. Use when the method, the consumables and the risk still have to be settled on paper: it selects the least invasive catalogued method whose damage-extent limit covers the damage, refuses a requested method the damage has outgrown, checks each consumable for shelf life at the planned date and for a process temperature the board construction tolerates, counts the thermal excursions the location has already taken, scores ...

Audit the record a repair or modification of a printed circuit board assembly leaves behind under ECSS-Q-ST-70-28C: score the mandatory header fields, require a location that names a side and a reference designator or grid rather than prose, require an approved method with the revision of the procedure that was followed, require every material to carry a batch and a shelf life still valid on the day it was used, match the verification activities recorded against the set the method demands, re...

Evaluate whether a solder joint on a printed board assembly may be reworked, and grade the joint the rework leaves behind, under ECSS-Q-ST-70-28. Use when a joint must be touched again and the iron settings, cycles already spent and workmanship criteria must all agree. Converts planned dwell into thermal exposure units on a doubling rule, so a short hot touch and a long warm one add on one scale, checks the total against the budget, refuses a lifted pad or a spent cycle count, then grades wet...

Determine whether an offgassing test article passes under ECSS-Q-ST-70-29 by applying every acceptance criterion at once: the per-compound concentration limits, the caps that apply to a whole chemical class, the governing toxicity total, the odour verdict and the budget on unidentified peak area. Use when identification, quantification and assessment outputs must be combined into one accept or reject decision that names the governing criterion, and a compound with no published limit has to fa...

Scope an item for the offgassing determination of ECSS-Q-ST-70-29, whose purpose is what a material releases into breathable cabin air rather than what it loses to vacuum. Decide whether the item shares the crew atmosphere, credit only a containment with no vent path, compute the loading as exposed mass over free cabin volume, choose between a material-level test and an assembled-article test from the material count and the build processes applied, judge whether an existing report still cover...

Design the collection train that captures the products of an ECSS-Q-ST-70-29 offgassing run: order the stages so condensables meet a cold surface before they reach a sorbent, size each sorbent bed so the swept volume stays under its breakthrough volume with a safety factor, check every cold finger sits far enough below each compound's condensation point, then combine the stage efficiencies into the capture fraction actually delivered per compound. Use when a trap, sorbent or cold-finger arran...

Determine the concentration of each offgassing product from its chromatographic response under ECSS-Q-ST-70-29: subtract the system blank, convert peak area to mass on the bracketing calibration rather than an extrapolated one, correct for recovery, then normalise to sample mass and to vessel volume so both figures stay traceable. Use when identified peaks must become defensible concentrations feeding the toxicity and acceptance steps, and a below-limit result has to be reported as below-limi...

Determine whether an offgassing-tested material may be installed in a crew compartment, and at what mass, under ECSS-Q-ST-70-29. Use when a tested material is being taken into the ECSS-Q-ST-70C selection and the ECSS-Q-ST-70-01C contamination control. Turn each specific yield and the installed mass into the concentration it contributes to the sealed free volume, ratio every contribution against its allowable, sum the ratios into one mixture index, invert the relation for the mass the compartm...

Define the exposure conditions of an ECSS-Q-ST-70-29 offgassing run: fix the set-point temperature and its tolerance band, count the dwell from thermal stabilisation rather than from the moment the vessel was closed, and pin the environment as evacuated below a pressure ceiling or purged with dry nitrogen at an adequate flow and purity, then grade a recorded profile on effective in-band dwell, excursion count and peak deviation. Use when a conditioning run has to be specified before it starts...

Assess the facility blank, analytical calibration and contamination controls behind an offgassing run under ECSS-Q-ST-70-29. Use when a crew-compartment offgassing result is reported, re-run or disputed. Subtract the facility blank from every reported compound and mark a net that fell under the quantitation limit as not-quantified, return the blank as a fraction of the gross reading, grade the curve on point count, response-factor spread and its age against the validity window, recover the ch...

Evaluate the acceptability of the odour an offgassing sample presents to a trained sensory panel under ECSS-Q-ST-70-29: keep only the scores of judges currently qualified on the reference set, check the panel is still large enough once they are dropped, average the intensity ratings, test the spread for a panel that did not agree, and grade the result against the acceptance rating. Use when an offgassing test has produced panel scores and they must become a defensible odour verdict rather tha...

Identify the offgassing products a material releases into a crew-compartment atmosphere from chromatographic and mass-spectrometric evidence under ECSS-Q-ST-70-29: grade each peak on retention-index deviation and spectral match score, hold a co-eluting pair back for a second technique, demand orthogonal confirmation for products driving the toxicity total, and account for the area left unidentified. Use when a test house returns an offgassing chromatogram and the peak list must become a defen...

Prepare the test item for a crew-compartment offgassing determination under ECSS-Q-ST-70-29, where representativeness governs: size the item so the chamber sees at least the loading the cabin will see, compare the achieved loading against the cabin figure, keep the item small enough relative to the chamber that the atmosphere stays well mixed, refuse a solvent wipe, bake-out or purge that strips the very products the test looks for, require a completed cure and an item inside its post-cure ag...

Document an offgassing test under ECSS-Q-ST-70-29 by assembling the report and checking it holds together: the article and run identification, the product inventory, the concentration table, the toxicity and odour assessments and the stated conclusion, with every product cross-checked across the three tables and every stated total recomputed from the rows it claims to summarise. Use when a completed offgassing campaign must become a traceable report and a conclusion that contradicts its own t...

Assess the offgassing load of a material or assembled article against the spacecraft maximum allowable concentrations under ECSS-Q-ST-70-29: scale each vessel concentration to the predicted cabin concentration for the flown quantity, form the ratio to its SMAC, add those ratios inside each toxicological group and take the governing group total as the T-value. Use when offgassing concentrations must become a crew-exposure verdict and a product with no published SMAC has to be surfaced rather t...

Determine whether a proposed electrical connection is a solderless wrapped connection the ECSS-Q-ST-70-30 requirements govern, and which controls it takes on. Use when a wrapped joint, a terminal post or a backplane is being brought under the wire-wrapping standard. Test the joining method, test the post for the sharp corners the wire has to bite into, test the conductor for solid construction and a gauge inside the covered span, count the gas-tight contact areas the wrap would produce from t...

Validate that a wrapping operator is certified for the job in hand under ECSS-Q-ST-70-30C personnel rules. Use when an assignment or a certification file is reviewed: treat every wire-gauge and terminal-type pair as its own endorsement, weigh the theory result and the accepted practical wraps behind it, hold the certification period and the vision check in date, suspend an endorsement whose combination has gone unworked past its continuity window, and return the status of each endorsement wit...

Verify the pull-off evidence behind a lot of wire wraps under ECSS-Q-ST-70-30C quality rules. Use when the destructive sample is planned or graded: size the sample from the lot, hold a first-article wrap for every operator, tool and gauge setup, read the minimum unwrap force the conductor gauge owes, compare each measured force against it and state the margin, refuse a sample cut from flight hardware instead of a process coupon, and return the lot disposition, whether that is acceptance, a ho...

Evaluate whether a wrapping post may be rewrapped under ECSS-Q-ST-70-30C rework rules. Use when a wrap has been removed and the connection has to be remade: count the removals the post has already taken against its allowance, require an unwrapping tool rather than a wrap dragged off with pliers, refuse a post whose corners the removal rounded or deformed, insist the used length of wire is cut away instead of wrapped again, size the wire the new wrap needs from the post perimeter and the turn ...

Assess the visual condition of finished wire wraps under ECSS-Q-ST-70-30C quality rules. Use when wraps are graded at the bench or on a sampling review: count the bare turns actually laid against the gauge minimum, raise an overlapping turn and a turn lifted off the post, measure each spiral gap against the conductor diameter and cap the gaps summed over the wrap, bound the overhanging end tail, group every finding as major or minor by whether it takes joint area away, and return per-wrap ver...

Verify that a conductor and a terminal post can carry a solderless wrapped connection under ECSS-Q-ST-70-30. Use when a wire gauge, a post section or a backplane terminal is being specified or substituted. Derive the bare conductor diameter from the gauge and the bare turns that gauge owes, take the post diagonal as a multiple of that diameter, budget the post length the planned turns, insulated turns and wrap levels consume plus end clearance, refuse an unalloyed tin finish on either part, n...

Evaluate a stripped wire end before it goes on a wrapping post under ECSS-Q-ST-70-30. Use when a strip length is set on the tool, or a bared conductor is questioned at inspection. Derive the strip length the planned bare turns, insulated turns and tail allowance need, compare the measured strip against it with a symmetric tolerance, return any nick or scrape as a fraction of the conductor diameter, return the diameter the jaws took out, grade the insulation set-back and damage, count the re-s...

Determine the wrap a solid-wire connection needs on a wrapping post under ECSS-Q-ST-70-30C process rules. Use when the turn schedule, the tightness and the position of a wrap are set or reviewed: read the bare-turn count the conductor gauge owes, add the insulated turns a modified wrap carries, compute the height the wrap occupies from the conductor diameter, subtract it from the usable post length so the level fits over the wraps already there, require every turn to seat on every post corner...

Audit the traceability record set behind a wrapped assembly under ECSS-Q-ST-70-30C records rules. Use when a build package is closed or reviewed: tie every wrap to the operator who made it and the tool that made it, hold the tool calibration in date on the wrap date rather than the audit date, require the tool setup verification inside its own short window and never after the work, demand a pull-test reference for each operator, tool and gauge group, flag records running out of retention, and...

Audit a wrapping tool set before it is released to production under ECSS-Q-ST-70-30. Use when a wrapping gun, bit or sleeve is issued, recalled or questioned after a loose wrap. Test that the fitted bit is certified and covers both the conductor gauge and the post diagonal in hand, return the calibration standing against the interval and its recall grace, return bit life consumed as a fraction of its wrap limit, grade the set-up sample on turns, overlap and end play, ratio the delivered tensi...

Evaluate whether one painted batch or area may be accepted and record the evidence that says so. Use when a coat has cured and acceptance is due per batch rather than per programme: size the dry-film-thickness draw from the painted area by integer arithmetic, reduce the readings, run the floor, ceiling and mean-band rules together so a healthy mean never rescues a thin point, grade the adhesion result and the cured state, and grade the inspection record itself so a lapsed gauge calibration ho...

Determine whether an applied coat meets its adhesion requirement under ECSS-Q-ST-70-31C using the pressure-sensitive tape method of ECSS-Q-ST-70-13C: choose the cross-cut spacing from dry film thickness and substrate hardness, refuse a film too thick for the lattice, convert whole and partly detached squares into a detached-area percentage, band it into the six-step rating, then grade every test area, the number of areas and the spread between them, folding in a pull-off strength where one is...

Verify the colour and appearance of an applied space-hardware paint against what the drawing specified. Use when a painted panel has to be graded before acceptance: compute the CIELAB difference against the reference chip and test it against the contract tolerance, test specular gloss against its band, tally appearance defects by mechanism family and by density over the inspected area, and, on a thermal-control finish, test solar absorptance and infrared emittance against their bands because ...

Scope a declared finish against the paint rules of ECSS-Q-ST-70-31C: decide whether a drawing note's coating is a paint system or a surface treatment outside these rules, assemble the declared layers into an ordered primer, intermediate and topcoat stack, report an inverted or repeated stack and a topcoat on unprimed metal, total the dry-film build with its tolerance band, and close on one in-scope, out-of-scope or incomplete-declaration disposition. Use when a finish schedule or coating draw...

Verify that a paint system is being applied by an approved method and to the specified build under ECSS-Q-ST-70-31C: reject a method the specification does not list, a brushed or rolled film on a thermo-optical surface and a dipped item carrying keep-out areas, convert the specified dry film into the wet film through volume solids, size the passes, theoretical coverage and paint volume after transfer losses, and grade the recoat interval and application-area conditions. Use when a coat is abo...

Verify that an applied paint system actually reached its cure state under ECSS-Q-ST-70-31C: read the logged profile hold by hold, award no credit below the minimum cure temperature and none plus an overbake finding above the qualified ceiling, convert every earning hold into equivalent hours at the reference temperature through the ten-degree rule, then test accumulated hours, continuous in-window dwell, the humidity window and the ramp rate between holds. Use when a cure log, an oven profile...

Assess the application environment before a coat is sprayed under ECSS-Q-ST-70-31C: grade booth air temperature and relative humidity against the paint system's declared window, derive the dew point from the Magnus relation and form the substrate dew-point margin, then convert an ISO 14644-1 cleanliness class into per-size airborne count limits and grade the measured counts. Holds a run whose air sits in window but whose hardware is cold enough to condense. Use when a spray-booth log, a subst...

Compute and grade the wet and dry film thickness of every coat in a paint system under ECSS-Q-ST-70-31C: reduce the tin volume solids by the thinner added at the gun, issue the wet comb target that lands a coat inside its dry band, grade the gauge population so a thin spot under the absolute floor is caught even when the mean reads acceptable, and sum the coat means into a system thickness. Use when a coat has to be sprayed to a thickness band, a gauge reading set needs a verdict, or a stack ...

Size the overspray halo of a spray set-up from gun stand-off and fan angle under ECSS-Q-ST-70-31C, turn it into the masking margin each keep-out zone earns from its category, and grade every declared mask footprint against that margin; then evaluate edge coverage separately, deriving the film a convex edge retains from its radius and the number of stripe coats a sharp edge needs to reach its minimum. Use when a masking plan, a keep-out clearance or an edge coverage requirement has to be settl...

Evaluate the imperfections found on an applied coat under ECSS-Q-ST-70-31C and turn them into a disposition: group each one under a defect family -- run, sag, orange peel, pinhole, inclusion, contamination -- scale that family's size and density allowances by the surface it sits on, grade it against both, then map a breach to a local rework, a strip and recoat or a referral, escalating anything out of limits on an optical face. Use when a post-application inspection record has to be dispositi...

Verify that a paint, primer or hardener batch is under the material control ECSS-Q-ST-70-31C expects before it is mixed: confirm the batch record carries its traceability items, turn manufacture date and declared shelf life into an expiry and the days left at the intended use date, charge logged over-temperature storage against that remaining life, screen the declared total mass loss and condensable figures against the vacuum outgassing limits, and close on one release, retest or reject dispo...

Validate that a painting process and the facility running it are qualified to coat flight hardware. Use when a booth, a material and a crew have to be signed off together before production spraying: size the witness coupon set the coating application owes, grade every process parameter against its qualified window, grade the booth environment including particulate class and the dew-point margin the substrate holds over the air, check that the operators who sprayed the coupons were still certi...

Evaluate candidate primer and topcoat pairings for one item under ECSS-Q-ST-70-31C and return the system to apply: screen out a primer the substrate will not bond to and a topcoat not qualified over that primer, reject a candidate the mission atomic oxygen, ultraviolet dose or thermal cycle range outruns, degrade beginning-of-life solar absorptance over the ultraviolet dose, rank what survives on end-of-life absorptance and absorptance-to-emittance ratio against the thermal role, and name eve...

Audit the per-unit painting record that has to survive the paint shop, and name every gap in it. Use when a coated unit is being released on its paperwork: check that the record states unit, drawing issue, primer and topcoat lots, operator and inspection result, that every application parameter from mix ratio to cure duration is actually stated rather than implied, that the mixed material went on inside its pot life, that each lot was inside its shelf life when mixed, that every applied lot w...

Determine whether a local defect in a cured paint may be touched up in place or has to go back for a full strip. Use when a repair is proposed on flight hardware: resolve how deep the defect reaches and therefore what has to be rebuilt, sum old and new repairs against the allowed fraction of the painted area, spend one unit of the re-application budget that area carries, project local film thickness after the abrade and the new coat against the ceiling, and price the added mass against the un...

Assess whether an existing paint system may be stripped from a space-hardware part and what may go back on it. Use when a full strip is proposed rather than a local touch-up: resolve the standing of the stripping method against the substrate as permitted, conditional or prohibited, accumulate the substrate loss this strip adds to what earlier strips already took, compare it with the wall the drawing keeps, count the further strips the part will still carry, land the stripped surface in the ro...

Derive and audit the substrate preparation a paint system owes under ECSS-Q-ST-70-31C: build the ordered degrease, abrade, rinse, chemical conversion, dry and mask sequence the substrate and the item's keep-out areas demand, compare the as-performed sequence against it for missing, unrecognised, repeated or out-of-order steps, apply the prepared-to-first-coat time window, confirm every declared bare area is actually masked, and close on ready-to-coat, rework-required or re-prepare. Use when a...

Assess whether a prepared substrate is genuinely fit to receive its first coat under ECSS-Q-ST-70-31C: read the water-break observation only when it was held long enough to be evidence, compare non-volatile residue and particulate obscuration against their limits, grade the abrasion profile against a two-sided roughness window that fails both too smooth and too rough, compute the substrate dew-point margin and coating-area humidity, and separate a surface failure that means preparing again fr...

Evaluate candidate alloy states against the stress-corrosion-cracking acceptance rules of ECSS-Q-ST-70-36C. Use when a field of alloys has to be narrowed for an application whose SCC criticality is already known: read the published resistance rating of each state, take a rating step off any candidate whose sustained tensile stress acts along the short-transverse grain direction, apply the acceptance rule the criticality imposes so a critical item needs a resistant state outright and takes an ...

Scope the stress-corrosion-cracking discipline over a metallic parts list under ECSS-Q-ST-70-36C. Use when a hardware list mixes aluminium, titanium, carbon and low-alloy steel, stainless steel, nickel, copper, magnesium and refractory metals with non-metallic items and the SCC control boundary has to be drawn before any alloy is chosen: normalize each declared material onto a known family, let a coating take the scope of its substrate rather than its own composition, separate the families ca...

Verify that the temper or heat-treatment state governing stress-corrosion-cracking resistance is the one actually delivered, per ECSS-Q-ST-70-36C. Use when a drawing calls an overaged or tempered-back condition and only a conductivity or hardness reading evidences what arrived: read the resistance rating the specified state carries, grade the reading against that state's acceptance window with both edges inclusive, and when it falls outside, search the same alloy's other registered states for...
