Data Quality Requirements
| requirement_id | Applies to | Requirement | Evidence |
|---|---|---|---|
part_identity | reference product | Demonstrate dedicated capacitor interface and external part delivery, with family, drawing/revision and completion state. No cross-family mass-equivalence claim. | customer/supplier drawing and delivery specification |
route_coverage | actual line | Audit every actual input, formulation, reaction, utility, packaging, treatment and direct release. A source chart or conditional card does not establish absent exchanges. | BOM, make/buy matrix and control permits |
period | all data | Use one complete coherent period including setup, idle, rework, rejects and stocks; retain supply geography, voltage/pressure and supplier technology. | production and utility reconciliations |
uncertainty | every amount and identity | Retain calibration, assays, detection limits, supplier substitutions and uncertainties. No empirical mass, yield, energy or emission range is supplied by this PCR; collect actual values. Missing identity or amount stays explicit and blocks unqualified downstream use. | measurement and supplier evidence |
9. Validation Rules
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
identity | part_gate | Reject absent capacitor-specific interface, missing required qualifiers, undocumented external-part status or complete functional capacitors presented as parts. | |
measurement | all inventory | Require positive calibrated net accepted shipped mass for the exact configuration and period; verify every count/area conversion and each per-kg denominator, packaging exclusion and collection aggregation. | |
make_buy | upstream links | Check purchased processing states, upstream burdens once, internal-transfer cancellation and no duplicate embedded metal, binder, solvent or rubber. Completed steps and downstream completion must match delivered state. | |
species | chemical and waste rows | Verify specific flow identity, property/unit, species, moisture/assay and compartment. Captured dust/sludge is waste, not released emission. Assess bath gas and solvent/decomposition products individually; fuel carbon alone does not validate CO or NOx. | |
coverage | data package | Resolve every applicable conditional route with actual recipe and state. not_applicable requires absence evidence; unknown is incomplete. Report checks performed/skipped and unresolved provider/UUID/quantity gaps; no universal BOM or numeric default may close a gap. |
10. Published Dataset Profile
| Field | Value |
|---|---|
| dataset_role | Foreground primary unit-process package for one dedicated capacitor part and declared completion gate |
| downstream_use | secondary_dataset; background_dataset after independent review and provider linkage |
| allowed_use | Production input to a matching downstream capacitor model at its actual supplied state |
| excluded_use | Complete-capacitor footprint or service-life claim; mass substitution across families, recipes or completion states; automatic CPC membership of unverified parts |
| required_metadata | All reference qualifiers; actual process and route coverage; net denominator; supplier delivery and transport/treatment links; allocation; geography/period; source editions |
| required_quality_disclosure | Primary-data coverage; missing species/UUID/provider identities; formulation and quantity gaps; uncertainty; conditional absence evidence; allocation and substitutions |
| update_trigger | Changed drawing, part interface, family, grade, supplied treatment, recipe, make/buy route, utilities, control, yield, measurement or acceptance state |
