9. Validation Rules
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
identity | dataset | Verify accepted dedicated44918 part and actual boule/wafer/device/IC/FPD, mask/reticle, assembly or handling host. Explicitly review chapter69 ceramic parts,7019/7020 technical and7017 laboratoryglass, general independent components/infrastructure/consumables. Each exchange own chemistry/grade/supplied state/native property/provider; unknown notzero. | |
denominator | all inventory rows | All inventory uses the same accepted cohort and common period. Verify calibrated accepted net mass and N; reject and packaging mass excluded. Check q_item=Q/N then normalization by same mean M; mixed configurations are invalid. | |
double_count | make_buy | Reconcile complete bought modules versus own materials and operations, retained fills/accessories versus factory consumption, paired internal transfers and external inputs. Count each actual burden once. | |
water_close | physical water records | For each term use its own measured water fraction, density and wet/dry basis: fresh and input moisture plus reaction water and beginning stocks minus final stocks, retained product, discharge and evaporation; internal returns cancel paired. Investigate measured closure against combined sampling/meter/allocation uncertainty; no universal tolerance. | |
species_close | material and chemical records | Close each contained metal/chemical separately using each input, product, scrap, sludge, liquid and release own matched assay and dry/wet basis, reaction stoichiometry and stocks. Gross mass is not contained element. No all-inventory mass rule applies to energy or transport. | |
solvent_close | solvent records | Distinguish retained solvent, recovered return, captured liquid/media, demonstrated destruction, wastewater/non-air residual and actual species air release. Capture is not destruction; an unexplained residual must be investigated, not assigned to air. | |
utility_close | energy records | Reconcile purchased imports, actual on-site generation, exports and storage changes with assigned fabrication/finish/integration/test/dispatch loads in the same period and units. Shared row ONLY unassigned residual; investigate negative residual against period, unit and combined measurement uncertainty without clipping. | |
steam_close | steam and condensate | Use supply kg times supply own MJ/kg and return kg times return own MJ/kg at measured pressure/temperature relative to common zero. If gross supply, subtract return once; if already-net invoice, do not subtract again. Keep physical steam/condensate mass balance independent from energy. | |
species_emissions | air releases | Validate every emitted species and compartment independently. Fuel carbon balance cannot alone establish CO or NOx. NO2 mass is not NOx reported as NO2 equivalent; keep reporting conventions and actual species identities distinct. |
