1. Scope and Applicability
This PCR covers factory production of physical parts designed principally for electrical transformers, static converters, or inductors: magnetic cores, windings and coil subassemblies, dedicated insulation and terminals, converter-specific busbars and populated boards, housings, cooling parts, and dedicated subassemblies. Finished apparatus, generic upstream materials or components, manufacturing services, installation, maintenance, use losses, and end-of-life are excluded. Declare the concrete part family and include only route operations and atomic exchanges that apply.

Structured rule index
This index comes from verified structured.yaml and retains the canonical English rule text.
System boundary rules · 3
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
boundary_rule_1 | foreground | Include applicable forming, winding, board assembly, molding, joining, treatment, testing, rejects, utilities, direct emissions and packing through factory gate. | oria-et-al-transformer-lca-review-2026, iea-pvps-lci-photovoltaic-systems-2020 |
boundary_rule_2 | upstream linkage | Use linked upstream datasets for purchased inputs and inbound transport; never hide them in an aggregate input. | iea-pvps-lci-photovoltaic-systems-2020 |
boundary_rule_3 | exclusions | Exclude complete apparatus manufacture/use, losses, installation, distribution and end-of-life unless separately expanded and reported. | eu-transformer-regulation-548-2014, oria-et-al-transformer-lca-review-2026 |
Allocation rules · 3
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
allocation_rule_1 | multiple part families/routes | Subdivide independently metered lots before allocation; do not average unlike routes without declaring the production mix. | |
allocation_rule_2 | shared records | Allocate using a causal driver such as machine time, thermal load, board area, or treated area; use mass only when demonstrated. | |
allocation_rule_3 | scrap/rejects | Keep scrap as waste without avoided-production credit inside the gate result; disclose any separately modeled co-product. |
Validation rules · 6
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
validation_rule_1 | category | Reject complete apparatus, generic material, or service outputs. | un-cpc-3-0-structure-2025, eu-transformer-regulation-548-2014 |
validation_rule_2 | reference flow | Confirm exactly 1 kg dry net conforming part; exclude and separately report removable packaging. | |
validation_rule_3 | completeness | Confirm each applicable material, utility, waste, and direct emission is one atomic row; support absent routes. | oria-et-al-transformer-lca-review-2026, iea-pvps-lci-photovoltaic-systems-2020 |
validation_rule_4 | calculation | Recalculate normalization, conversion, allocation shares, and residual; reject unexplained differences. | |
validation_rule_5 | identity/unit | Verify UUID, flow type, property, unit group, Chinese baseName, and condition; never use a proxy for unresolved identity. | |
validation_rule_6 | disclosure | Confirm sources, records, site, period, part family, materials, board state, treatment, and packaging. |
Processes and inputs/outputs · 1
| Process ID | Process name | Input flows | Output flows |
|---|---|---|---|
part_fabrication_assembly | Route-qualified part fabrication, assembly, testing and packing | 16 | 7 |
