Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_product_identity	reference product	Product classification, model, size, polymer composition, function, and net mass resolve to one released sale unit.	specification, meter, laboratory, mass-balance, and provider-review records
dq_temporal	all foreground rows	Use a representative continuous 12-month period or justify a complete shorter campaign; align numerator and denominator periods.	specification, meter, laboratory, mass-balance, and provider-review records
dq_technology	all processes	Identify forming, joining, oven, finishing, abatement, and treatment technology; keep materially different routes separate.	specification, meter, laboratory, mass-balance, and provider-review records
dq_mass_balance	materials, product, wastes, and emissions	Close polymer, solvent, water, refrigerant, and product balances and investigate gaps.	specification, meter, laboratory, mass-balance, and provider-review records
dq_atomic_identity	all inventory rows	Keep one exact material, carrier, waste, or elementary substance per row; add rows for unlisted identities.	specification, meter, laboratory, mass-balance, and provider-review records
dq_provider_links	purchased inputs	Link exact upstream provider datasets or disclose each unresolved link without a combined substitute.	specification, meter, laboratory, mass-balance, and provider-review records

9. Validation Rules

1. val_reference_identity: Reference flow is Product, CPC 28243, Mass, Units of mass, kg, and the confirmed UUID.
2. val_reference_amount: Normalized net product output is exactly 1 kg; packaging mass is excluded.
3. val_route_atomicity: Every card contains one exact exchange and its actual route condition holds.
4. val_carrier_separation: Electricity, steam, hot water, natural gas, diesel, LPG, R-134a, and every material, waste, and emission remain separate.
5. val_no_estimate_range: No AI, author, or reasoned-estimate quantity range is used; missing quantities remain foreground records.
6. val_balances: Polymer, solvent, water, refrigerant, and product balances close to records.
7. val_bilingual_identity: EN/ZH process_id, direction, flow_type, row_id, order, controlled values, source_id, and UUID align.
8. val_uuid_gate: Add a non-reference UUID only after hybrid search and direct state-code-100 dual verification.

10. Published Dataset Profile

Field	Value
dataset_role	Site-specific factory-gate foreground package for one declared CPC 28243 product and route.
downstream_use	Link exact upstream providers and downstream distribution, use, and end-of-life to construct a lifecycle model.
allowed_use	Validated product-specific inventory, hotspot analysis, supplier engagement, and downstream LCA.
excluded_use	CPC-wide defaults, unsupported comparison of different functions or lives, conformity claims, or substitution for CPC 28250 methodology.
required_metadata	All reference qualifiers, route, site, period, allocation, cutoffs, providers, measurement, uncertainty, and destinations.
required_quality_disclosure	Primary-data share, meter/lab coverage, balance closure, unresolved UUIDs/providers, route exclusions, allocation, missing analytes, and representativeness.
update_trigger	Change in formulation, function, thickness, life, technology, energy, refrigerant, treatment, packaging, site, or period.
