Calculation Rules
| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
|---|---|---|---|---|---|
| period_normalization | all inventory rows | Use each attributable period exchange Q / D; preserve original numerator units; reference_product = 1 kg. | Q; D; cp_mass | q_ref | rangemaster-manufacture |
Data Quality Requirements
| requirement_id | Applies to | Requirement | Evidence |
|---|---|---|---|
| identity | all applicable rows | Confirm actual UUID/property/unit, grade/formulation, fuel, supply state/geography and downstream waste treatment interface; unresolved is explicit, not a generic substitute. | Actual supplier/site records and direct identity reads |
| coverage | all exchanges | Same configuration/BOM/period and tests; actual route absence documented. Missing actual quantities, ranges or recipes remain unknown, not zero; no factory default inferred from brochure use specifications. | Measured raw records, route matrix and uncertainty |
9. Validation Rules
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
| reference_check | reference_product | Require positive D and N, calibrated accepted net same-configuration mass, and same-period Q including rejects/rework; 1 kg output and Q/D must reconcile. Cooking/heating hybrids require principal-function/classification authority evidence. | esse-cookers; aga-rayburn |
| water_closure | physical water and moisture records | Each wet stream uses its own measured moisture and wet/dry basis, including product, sludge, wastewater and residuals. External water plus input moisture plus beginning stock and reaction-generated water equal retained product moisture plus end stock, evaporation, discharge and reaction consumption. Pair internal returns; do not count circulation repeatedly. Investigate residual using actual combined meter/sampling/allocation uncertainty, not universal tolerance. | rangemaster-manufacture; jrc-foundry-2024 |
| metal_species_closure | physical material and species records | For each actual element/species, every input, product, scrap, slag, sludge, wastewater and release uses its OWN matched assay and wet/dry basis. Include beginning/end stocks, reaction transformations, retention and paired internal return cancellation. Gross material mass is not contained iron/chromium/nickel; investigate closure with actual combined measurement, sampling and allocation uncertainty. | jrc-foundry-2024 |
| solvent_closure | physical solvent records | For each actual solvent, reconcile fresh input and beginning stock against end stock, retained product, recovered solvent, solvent in capture media, verified destruction, air releases and non-air residues. Unknown solvent residual is not automatically an air emission. Recovery/capture is not destruction; paired returned solvent cancels once. Investigate residual against actual combined uncertainty; no assumed solvent for absent route. | rangemaster-manufacture |
| utility_closure | utility records | Process and shared-service rows reconcile SAME measured site period and units; shared service is only the unassigned residual. Do not add whole-factory meter totals to assigned submeters. Reconcile imports, actual onsite generation, exports, storage changes and steam/condensate returns; investigate negative residual using matched meter, sampling, period, stock and allocation uncertainty, never clip. Bought power is not source-specific incineration output; generation fuel is not purchased power. | rangemaster-manufacture |
| emission_evidence | elementary emissions and fuel records | Factory combustion/firing releases remain production; customer use remains separate. Fuel carbon closes total carbon but cannot prove CO, NO or NO2 amounts. Require species-specific measured/factor evidence, actual compartments and fossil/biogenic split. NOx as NO2 equivalent is a convention, not pure NO2; measured size-resolved PM10/PM2.5 are distinct, do not infer from unsized dust. Capture media and treatment residues need their own assays. | jrc-foundry-2024; esse-cookers |
