Calculation Rules
| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
|---|---|---|---|---|---|
| normalize_mass | all inventory rows | q_ref = q_item / M; q_item = exchange amount per one accepted finished machine; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |
Data Quality Requirements
| requirement_id | Applies to | Requirement | Evidence |
|---|---|---|---|
| identity | all exchanges | Actual product/species/provider/compartment identity and units must be resolved before dataset completion; no generic basket, unknown-as-zero or UUID-hit-driven scope restriction. | Supplier specification; direct flow identity; BOM |
| finite_balance | physical streams | For each contained metal/species j separately, calculate each stream mass times its OWN matched assay on a declared wet/dry basis. Include purchased material, opening/closing stock, accepted product, scrap, dust, slag, sludge, wastewater and environmental releases plus reaction transformation. Never equate gross scrap/sludge mass with contained metal or reuse feed assay for product/waste. Close actual water: external water plus input moisture and opening stocks plus reaction-generated water equals shipped retained water, waste/effluent moisture, measured evaporation, reaction-consumed water and closing stocks. Pair and cancel internal return transfers. Each moisture term has its own matched assay, basis and uncertainty; circulating water is not external input. Close each actual solvent species with formulation assays for purchased input, stocks, retained coating, recovered solvent, capture media, waste/liquid transfers, actual destruction and measured air releases. An unexplained residual is investigated, never automatically an air emission. Use combined measurement, sampling and allocation uncertainty, not a universal closure tolerance. | Own assay per term; stocks; reaction and uncertainty records |
| no_defaults | all rows | Collect measured site/configuration quantities; no universal machine weight, manufacturing energy, yield, operating productivity, lifetime or emission factor. Not-applicable needs route evidence and differs from measured zero/unknown. | Full representative period; route register; retained records |
9. Validation Rules
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
| validate_reference | combine_harvester | Verify N>0, D>0 and M same period/configuration, calibrated net acceptance, declared shipped header/fills, matching reference and denominator; reject weight/productivity proxies. | |
| validate_physical | physical water/material/species rows | For each contained metal/species j separately, calculate each stream mass times its OWN matched assay on a declared wet/dry basis. Include purchased material, opening/closing stock, accepted product, scrap, dust, slag, sludge, wastewater and environmental releases plus reaction transformation. Never equate gross scrap/sludge mass with contained metal or reuse feed assay for product/waste. Close actual water: external water plus input moisture and opening stocks plus reaction-generated water equals shipped retained water, waste/effluent moisture, measured evaporation, reaction-consumed water and closing stocks. Pair and cancel internal return transfers. Each moisture term has its own matched assay, basis and uncertainty; circulating water is not external input. Close each actual solvent species with formulation assays for purchased input, stocks, retained coating, recovered solvent, capture media, waste/liquid transfers, actual destruction and measured air releases. An unexplained residual is investigated, never automatically an air emission. Use combined measurement, sampling and allocation uncertainty, not a universal closure tolerance. | |
| validate_energy | utility rows | Reconcile each utility in one site period/unit: purchased imports plus actual generation plus opening storage equals assigned fabrication/coating/assembly/test/dispatch use plus unassigned residual plus exports and closing storage/loss. Shared services carry only causal share of unassigned residual. Verify negative residual against period, unit, stock and meter uncertainty; never clip it to zero. Purchased heat, own fuel generation and recovery transfers are distinct. Meter actual recovered test-cabin heat and paired internal transfer; cancel internal transfer on site aggregation. Reduce actual external heat requirement only through its measured resulting meter consumption; do not add an avoided-power credit or a second avoided-heat credit. Exports, if any, need separate measured destination and allocation. | |
| validate_test | filling_testing | Separate retained diesel/oil/refrigerant from actual factory consumption, recovery and leak; resolve CO, NO and NO2 with species-specific evidence, not fuel carbon alone. Include actual pre-gate test crop and waste, exclude later farm use/yield. | kappa-claas-test |
| validate_coverage | dataset | Audit all actual routes/BOM/exchanges and upstream links. Incomplete UUID, amount, conversion, species or compartment prevents complete dataset status; candidate methodology finite check is not publication or factual factory verification. |
