Data Quality Requirements
| requirement_id | Applies to | Requirement | Evidence |
|---|---|---|---|
configuration | device | Actual model/delivered BOM and drive/suspension/safety drawing override marketing conflicts; do not extrapolate one industrial or household recipe. | drawings; nameplates; acceptance |
period | all exchanges | Complete common period, setup, idle, test, rework/reject and stocks; disjoint assigned utilities and causal residual allocation. | meter/lot reconciliation |
uncertainty | physical quantities | Retain calibration, representative moisture/species sampling, detection limits and allocation uncertainty. No empirical unit mass, yield, energy, lifetime or emission range is supplied. | measurement and laboratory records |
links | upstream and treatment | Resolve actual provider technology, delivered processing state, geography and treatment separately; a flow UUID is not an upstream footprint. | supplier and treatment receipts |
9. Validation Rules
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
identity | reference product | Require standalone clothes-water extraction, every qualifier, complete delivered device and correct reference link; distinguish household laundry capacity from net device mass and washing/heated-drying categories. | |
denominator | all inventory | Require positive N and D from calibrated accepted same-configuration records, verify Q includes rework/reject, and q_ref = Q/D = (Q/N)/(D/N); reject package/test-water/reject mass or cross-configuration means. | |
buy_once | component state | Verify every completed purchased motor/drum/control and embedded materials/upstream burdens once; actual site-made components activate full recipes and stages; match paired transfers. | |
balances | physical water, metal and solvent | Execute water_close, metal_close and solvent_close for applicable records including all stocks, reactions, wet/dry and own-term assays plus paired returns. Explain residual against actual combined uncertainty, not an arbitrary universal tolerance or invented loss. | |
utilities | site meters | Execute utility_residual with same site interval/unit and disjoint test/process loads; imports, generation, exports/regeneration and storage must reconcile. Reject whole-factory-plus-submeter double charge and unexplained negative residual. | |
species | actual emissions | Captured material is waste, not emitted metal; separate actual species and receiving compartment. CO/NO/NO2 require their own evidence; solvent destruction and recovery differ from air release. | |
coverage | data package | Report accepted input, checks performed/skipped, findings and completeness; unknown UUID/provider/amount is incomplete, not zero. Conditional absence needs actual BOM/test evidence. Resolve all applicable additional exchange gaps before unqualified secondary use. |
10. Published Dataset Profile
| Field | Value |
|---|---|
| dataset_role | Foreground primary unit-process data package for one complete configured extractor through manufacturer gate |
| downstream_use | secondary_dataset; background_dataset |
| allowed_use | Manufacturing input to the same delivered device with reviewed upstream/treatment links; later use model separately |
| excluded_use | Standalone complete cradle-to-gate claim with missing providers; functional laundry equivalence, default lifetime or operating savings; washer/heated-dryer substitution |
| required_metadata | All qualifiers; factory period and N/D/Q; make/buy; active/absent routes; acceptance/test load; measured utility reconciliation; supplier/transport/treatment links; allocation and source editions |
| required_quality_disclosure | UUID/provider and recipe gaps; source conflict; no empirical ranges; measured uncertainty; skipped/inconclusive checks; absence evidence and substitutions |
| update_trigger | Changed model/BOM, motor/drive/suspension/safety, materials/finish, make/buy, acceptance, site utility, calibration, allocation or supplier state |
